608 Ball Bearing Material 608 bearing with dust cover and sealing cover, with dust cover indicated in the model suffix zz (608zz), rubber cover in the model suffix 2RS (608-2RS). Materials are carbon steel, bearing steel (GCr15), stainless steel, plastic, ceramics, etc. The cages are nylon cage, iron cage, copper cage, and so on.

The rolling elements of a ball bearing can be made of a hardened tool steel alloy and can even be coated with additional coatings (such as chrome) to further increase the wear and corrosion resistance of the ball bearing. Stainless steel ball bearing systems are also readily available if corrosion or degradation is an issue in a specific application. If significant thrust loads must be sustained, whereas a journal bearing would be almost useless, a cylindrical or needle rolling bearing system is the ideal bearing for the job and can readily be specified to meet a wide range of applications.

A bearing is a mechanical component that usually has a rolling or sliding component that further reduces friction between the moving shaft and the stationary hole or reference point. The most common and easiest to identify bearing type is probably the ball or roller bearing. These types of bearings consist of an inner race that is usually directly (press) fitted onto the inner shaft. The rolling elements (balls or tapered rollers) then roll along the opposite side of the inner race and they are all enclosed in one unit by the outer race. not difficult to visualize how this system allows relative motion between the inner and outer raceways, via the relative rolling of the rolling elements. The rolling elements in the bearing cartridge can be lubricated and sealed completely in between the inner and outer raceways of the bearing in order to prevent any exposure to environmental contaminants.

The simplest kind of bearing goes by a number of different names, such as the plain bearing, the journal bearing, or the bushing bearing. This type of bearing system is simply an engineered running clearance fit that is typically constructed from a bushing and a shaft. This simple hole/shaft interface is designed to facilitate rotational motion of the journal within the bearing hole typically with an external lubricating compound designed to fill in the clearance spaces between the shaft and hole. In this way, there are no intermediary rolling or sliding elements that allow motion. Journal bearings are typically built nowadays by leveraging advanced materials technologies such as oil-impregnated bushings in order to build a joint that has a low rolling/sliding resistance friction associated with it.

Basic code used to indicate the bearing bore, diameter series, width series and type, generally up to five digits, first divided as follows.

608bearing dimensions

because the successful operation of these journal-bearing systems is heavily dependent on the presence of saturated lubrication with each rotation of the shaft within the bushing. A failure of the lubrication system normally leads to rapid and catastrophic failure of the entire machine. If an active lubrication system is not feasible for a specific application that must sustain high speeds as well as variable dynamic load, it is recommended that a contact bearing system design be considered. bronze bushing These bearings are very simple in design, but they are almost always used in conjunction with a comprehensive, reliable, active lubrication system. (unlubricated) plain bearings that may be specified for low load, low-speed applications. These types of bearing systems typically use polymer bushings, which can be specified, but most industrial applications that use pillow block bearings are fully lubricated shaft/sleeve systems. It is important to note that these systems must be located in areas of the machine that are reasonably accessible for preventative maintenance or repair if needed

(3) bearing width series (that is, the structure, bore and diameter series are the same bearing width variation series) with the basic code from the fourth digit from the right. When the width of the system Figure 13-4 diameter series contrast as 0 series (normal series), most bearings in the code may not mark the width of the series code O, but for spherical roller bearings and tapered roller bearings, width series code 0 should be marked.

The number “608” in the bearing’s name represents its specific dimensions. The “6” indicates the type of bearing (deep-groove ball bearing), while the “08” represents the size of the bearing. The standard dimensions for a 608 bearing are 8mm (inner diameter), 22mm (outer diameter), and 7mm (width).

The 608 bearings are typically made of chrome steel, stainless steel, or ceramic. Each material offers its own unique advantages. For instance, chrome steel is durable and can handle high loads, stainless steel is corrosion-resistant, and ceramic bearings generate less heat and are suitable for high-speed applications.

The rear code of the bearing is used letters and numbers to indicate the structure of the bearing, tolerance and special requirements of materials, etc. There are a lot of post-designations, the following are a few common designations.

(1) Internal structure code is to indicate the different internal structures of the same type of bearing, with letters followed by the basic code. Such as contact angles of 15 °, 25 °, and 40 ° of the angular contact ball bearing with C, AC, and B, respectively, to indicate the different internal structures.

single row deep groove ball bearings are used in a wide variety of applications, they are simple in design, non-separable, suitable for high speeds

Dynamic bearing systems are, at their most basic level, simply a hole/shaft interface designed to allow relative rotation between components. Typically one of the parts is completely stationary while the other part rotates against it. Bearing system designs can range from very simple to very complicated, with many moving parts and components used to transmit motion through the system. A quick overview of the two most basic types of bearing systems and their limitations will provide an excellent introduction to the vast world of bearings and rotational motions.

The 608 bearing is widely used in various applications due to its versatility and durability. Some of the common uses include:

(4) bearing type code with the basic code right from the fifth digit (for cylindrical roller bearings and needle bearings and other types of code for the letter).

(1) bearing bore with the basic code from the right of the first digit. For the common inner diameter d = 20 ~ 480mm bearing bore is generally a multiple of 5, the two numbers indicate the bearing bore size by 5 divided by the quotient, such as 04 d = 20mm; 12 d = 60mm, etc.. For the inner diameter of 10mm, 12mm, 15mm and 17mm bearings, inner diameter code for 00, 01, 02 and 03. For inner diameter less than 10mm and more than 500mm bearings, the inner diameter of the method otherwise specified, see GB / T272-93.

The bearing’s front code is used to indicate the bearing’s sub-parts, with letters. For example, L indicates the separable ring of the separable bearing; K indicates the rolling body and cage assembly of the bearing, etc.

For low-cost applications where the bearing can be easily accessed for lubrication and maintenance, the main bearing may be a perfectly suitable design and can be used in many types of applications. However, if accessibility to the bearing is impossible and/or the bearing system should support high radial loads or axial loads, the designer should go ahead and start exploring the vast world of rolling contact.

(2) bearing diameter series (i.e., the same structure, the same inner diameter bearing in the outer diameter and width of the change in the series) with the basic code from the right of the third digit. For example, for to the heart bearing and to the heart thrust bearing, 0, 1 indicates that the special light series; 2 indicates that the light series; 3 indicates that the series; 4 indicates that the heavy series. The size comparison between each series is shown in the figure below. The dimensions of axial bearings are the same as those of radial bearings, except that 1 is used for the extra light series.

Deep-groove ball bearings are among the most commonly used types of bearings, designed to handle radial and axial loads from both directions. One of the most widely utilized models is the 608 bearing. These small yet powerful bearings are used in a variety of applications, from skateboards and roller skates to electric motors and household appliances.

(3) common bearing radial clearance series is divided into 1 group, 2 groups, 0 groups, 3 groups, 4 groups, and 5 groups, a total of 6 groups, radial clearance in order from small to large. o group clearance is commonly used clearance groups, in bearing code is not marked, the rest of the clearance groups in bearing code with / CI, / CZ, / C3, / C4, / CS respectively.

(2) bearing tolerance level is divided into 2, 4, 5, 6, 6X and 0, a total of 6 levels, in order from senior to low, its code / PZ, / P4 ‘/ PS, / P6, / P6X and / PO. tolerance level, 6X level only for tapered roller bearings; 0 levels for ordinary level, in the wheel bearing code is not marked.

The 6 in the 608 bearings represent the 6 series deep groove ball bearing, 0 is the size series, and 8 is the inner diameter of 8mm. Dimensions are 22mm outer diameter, 7mm height, and 8mm inner diameter. 7 steel balls with a diameter of 3.969mm.
