Then you will need to pay attention to how the bearings are assembled. If two bearings are too close together, you should use the O-assembly method so that the bearings do not interfere with each other. If this is not the case then the X-assembly method is perfectly suitable.

Be careful, in order to choose the preload (radial or axial) you must know the rigidity of all parts through software or experimentation. In your selection criteria, you must also consider the ideal material for your bearing. Bearings can be made out of metal, plastic or ceramic. The bearing material depends on its intended use. We recommend that you choose the most compression-resistant bearing. Keep in mind however that the material used affects the price of the bearing.

You may have heard of a plug gauge before and might be wondering what the difference between a plug gauge and a bore gauge is. While a bore gauge measures the size of a bore, a plug gauge is used to inspect the accuracy of the bore. This means that the plug gauge checks to see if the internal diameter falls within the specified tolerance to ensure its accuracy. The plug gauge should be able to fit into the bore without using much pressure and stay standing in the bore without falling over. Most commonly, the plug gauge will have two ends, one fitted to the lower limit of the bore and the other to the higher limit.

Rotation speed is another element that should be considered. Some bearings can withstand high speeds. The presence of a cage for cylindrical roller bearings and needle bearings allows for greater speeds than bearings without a cage. However, the choice of a higher speed is sometimes made at the expense of the load. You should also consider the possible presence of misalignment; some bearings are not suitable for this situation, such as double row ball bearings.

Bore Gauge

Each type of bearing can be deep-groove, spherical or insert. Deep-groove bearings are the most common. Insert bearings are deep-groove bearings which, like spherical bearings, effectively support misalignment.

There are several types of bearings, the four main types are: ball bearings, cylindrical roller bearings, tapered roller bearings and needle bearings.

Choice of lubricant is an essential factor in ensuring the proper functioning and long service life of bearings. Lubricant does the following:

Another factor to consider: depending on the use, you will need a rotating shaft (for example wheel drive bearings for cars) or a rotating hub (like for washing machine bearings).

Ball bearings are often optimized for radial contact: this means that they will be very useful if the force you want to bring into contact with the bearing is perpendicular to its axis of rotation. However, double row ball bearings are optimized for angular contact. Additionally, if you want to use a ball bearing for an axial load, it should be noted that this device only supports moderate axial loads. However, this flaw can be avoided by using a double-row ball bearing construction. As well as being low-cost, ball bearings are also the most compact, making them the most widely used type of bearing.

We therefore recommend this type of bearing for uses such as machine spindles, vehicle transmissions (from car to boat, helicopter), or the steering of car or truck wheels.

The most advanced type of bore gauge is a digital bore gauge that is either connected by cable to a readout or relies on wireless technology to read and transmit the data. These bore gauges are usually fitted with two to three anvils to measure with precision and some can even have extension attachments to measure wider and deeper bores. Variations in the design of digital bore gauges have allowed for some to be mounted with a handle to look like a caulking gun or pistol.

While ball bearings are the most common mechanisms, each device has its advantages and disadvantages. That is why we recommend that you compare each of these bearings to determine which is the ideal system for your requirements.

Tapered roller bearings can support radial, axial and combined loads (both at the same time). The loads can be very heavy, due to their high rigidity. If you are unsure between a ball bearing and a tapered roller bearing, be aware that a tapered roller bearing of equivalent dimensions can support heavier loads.

The Sylvac Digital Bore Gauge X_Treme XTD and the Sylvac Bore Gauge Xtreme 3 Digital BT are similar to the previously mentioned bore gauges except for the lack of the pistol design. The X_Treme XTD falls under the same series as the Pistol-grip X_Treme XTH while the Xtreme 3 Digital BT follows the Pistol-grip Xtreme 3 Holematic BT.

Bore GaugeMicrometer

Each type of bearing is specifically designed to support an axial or radial load. Some bearings can support both loads: in this case we refer to a combined load. If you have to support a combined load, for example, we recommend that you choose a tapered roller bearing. If you need a bearing capable of withstanding a high radial load, then we recommend a cylindrical roller bearing. On the other hand, if your bearing needs to support lighter loads a ball bearing might be sufficient as they are often less expensive.

The Moore & Wright Telescopic Gauge 315 Series comes as a 6 piece set to provide you with different sized gauges for your every need. The device features a spring loaded plunger that expands in the bore and locks directly. Additionally, the measuring faces undergo a process called micro-lapping which smooths the surface, ensuring that measurements can be taken with a higher degree of accuracy. The 6 pieces in the Moore & Wright Telescopic Gauge 315 set range from 8mm for the smallest size to 150 mm for the largest.

You will therefore need to pay attention to the bearing construction: insert and spherical bearings make it easy to support these misalignments. We suggest that you lean towards bearings with automatic alignment which automatically correct alignment defects caused by shaft bending or installation errors. Similarly, operating conditions are very important when choosing the ideal bearing. It is thus necessary to analyze the environment you will be using the bearing in. Your bearing may be subject to a number of contaminations. Some uses can lead to noise disturbance, impact and/or vibration.

CylinderBore Gauge

Compared to telescopic bore gauges and small-hole gauges, the dial bore gauge can perform the same function of measuring bore sizes but with a more direct approach. The dial bore gauge works by rotating a knob to extend and retract three anvils that point out from the body of the gauge. When the anvils are extended to match the size of the bore, the measurement reading will be sent to the dial mechanism to be read. Do take note that dial bore gauges would have to be calibrated before each use.

A bearing is a mechanical component whose function is to guide a rotating assembly. The bearing therefore allows the rotation of one element relative to another. Bearings are therefore high-precision parts that allow equipment to move at different speed levels by efficiently transporting notable loads. They must offer high precision and durability, as well as the possibility of working at high speeds with minimal noise and vibration.

Digital CylinderBore Gauge

Finally, each bearing has specific dimensions. These dimensions, expressed in mm, are subject to international standards. We therefore advise you to pay attention to the bore of the bearing, i.e. the inner diameter (always represented by the letter d), the outer diameter (represented by the letter D) and the width (represented by the letter B).

When it comes to bore gauges, there are many variations on the market. The main categories that bore gauges fall under are telescopic, small-hole, dial and digital.

The Moore & Wright Dial Bore Gauge 316 Series comes with a set of carbide tipped interchangeable contact points. These tips range from 6mm to 150 mm with a 0.01 mm resolution for dial readings and 0.001 mm resolution for the digital indicator for more accuracy. The Moore & Wright Dial Bore Gauge 316 Series also features unique self-centering capabilities for additional ease and accuracy when using it.

You have 2 choices: grease or oil. Generally speaking, grease lubrication is definitely the simplest and most efficient choice because it provides all the functions mentioned above and also allows for operation with low maintenance. However, if your bearing is integrated in an oil-lubricated machine, we recommend that you use the same lubricant system. In any case, the choice of lubricant will depend on three factors: the load, the type of operation (continuous or intermittent), and the speed of rotation.

If the bearing is subject to high loads, the operation is continuous and the rotational speed high, then oil lubricant is the ideal solution to ensure the proper functioning of your rolling system. On the other hand, if the loads are low and the speed limited then grease will be more than sufficient.

A small-hole gauge works slightly differently from the telescopic bore gauge and its usage is favored when it comes to measuring small bores. It comes in two styles: the half-ball and the full ball. The small-hole gauge is inserted into the bore and slowly adjusted until a light pressure is felt. It is then removed and measured against a micrometer or caliper. The full-ball gauge is easier to set and maintain as compared to the half-ball gauge which tends to have more spring that may make the measurement wrong.

They differ from spherical bearings in that they have a smaller swivel angle. The larger the swivel angle, the more the bearing will withstand misalignment.

Choosing a sealing system is essential in order to ensure the correct and long-lasting operation of a bearing; it is therefore important to ensure that the bearing is always well-protected from any impurities and external agents, such as dust, water, corrosive fluids or even used lubricants. This choice depends on the type of lubricant, the ambient conditions (and therefore the type of contamination), the fluid pressure and the rotation speed. To give you a good place to start, the fluid pressure is a determining factor in the choice of sealing system. If the pressure is high (in the range of 2-3 bars for example) a mechanical seal is ideal. Otherwise, the choice will be directly linked to the type of lubricant, grease or oil. For example, for grease lubrication the most commonly used solutions are: deflectors or washers, narrow passages that are machined or with grooves; in the case of oil lubrication the sealing system is often accompanied by the presence of a groove for oil recovery.

Like cylindrical roller bearings, needle bearings can come with or without a cage. If they have a cage then they can withstand a very high speed, while a needle bearing without a cage can support a very significant radial or axial load. Also note that these bearings are small in size, and as such have a small footprint. They are regularly used in gearboxes, for example.

This type of device is found in all applications such as, for example, the automotive industry, the aerospace sector, construction equipment, machine tools, etc.

DialBore Gauge

Telescopic bore gauges are one of the cheaper, albeit trickier options when it comes to bore gauges. Once the gauge has been inserted into the bore and locked in place, the handle is rocked in order to extract the exact bore diameter. This rocking movement compresses the two anvils that give the dimensions of the bore, which are fixed in place. The anvils are then measured using another tool such as a micrometer or caliper to read the measurement from the locked bore gauge. As the telescopic bore gauge relies heavily on the operator’s handling, human error may hinder the accuracy of the measurements collected.

Cylindrical roller bearings are also very robust and have a long bearing life. Additionally, some bearings can also support an axial load, provided that they do not have a shoulder on the inner and outer rings. If this is the case, you will not be able to use your bearing to support an axial load.

Bore gauges are essential tools used to measure the internal diameters of bores, which are simply holes. It is often used in the routine maintenance of equipment to check for the wear-out of parts for operators to know when they should change their equipment. When using a bore gauge, the base of the bore gauge will be inserted into the opening of the desired hole and adjusted to perfectly fit the diameter of the opening. Depending on the type of bore gauge, the setup and usage method may differ but nonetheless they all serve the same functions.

3-PointBore Gauge

Your bearing must therefore withstand this impact on the one hand and not be an inconvenience on the other. Another essential element to consider is the bearing life. Several factors, such as speed or repeated use, can impact the bearing life.

Examples of bore gauges that feature a pistol design would be the Sylvac Bore Gauge Pistol-grip X_Treme XTH and the Sylvac Bore Gauge Pistol-grip Xtreme 3 Holematic BT. With a measuring range of 2 mm to 300 mm, both models feature fixed anvils and a UKAS certificate for its rings. A difference between the two models is that the Sylvac Bore Gauge Pistol-grip X_Treme XTH uses s_connect proximity while the Sylvac Bore Gauge Pistol-grip Xtreme 3 Holematic BT has built-in integrated BluetoothⓇ technology on top of the s_connect proximity. Another difference lies in X_Treme XTH memorising 3 ring gauge values and the Xtreme 3 Holematic BT memorising 4 ring gauge values.

With a resolution of 0.01 mm and an accuracy of 0.004 mm, the Moore & Wright Digital Bore Gauge SCTHXY3M-MW Series can measure bores of up to 82 mm in depth precisely.

Its wide range of functions include buttons such as a preset master button that can be programmed according to your needs.

When choosing a bearing, you must consider several important factors. The first factor to consider is the load that the bearing can support. There are two types of loads: – axial load: parallel to the axis of rotation – radial load: perpendicular to the axis

Conditions of use can also influence your choice, especially when it comes to assembling the bearing. The rigidity and precision that your use requires must also be taken into account. In some cases, you can provide for the application of a preload in the assembly of your bearing to increase its rigidity. Additionally, the preload will have a positive impact on the bearing life and noise level of your system.

Like plain bearings, rolling-element bearings reduce friction in a rotating guide between two parts. Depending on the direction of the force, axial or radial, there are different types of bearings. Bearings are composed of rolling elements, usually balls, cylindrical or tapered rollers or needles.

Cylindrical roller bearings are able to support significant radial loads, or even very significant ones. There are several types of cylindrical roller bearings. They vary according to the number of rows of rollers (one, two or four) and whether or not there is a cage. A cage allows the bearing to support significant radial loads and a high speed. The absence of a cage allows the bearing to have more rows of rollers and therefore to support even heavier radial loads. The only disadvantage is that cylindrical roller bearings without cages do not tolerate as high speeds as the ones with cages.
