A ball bearing is a type of rolling bearing in which a ball is placed between the inner and outer rings that reduces rotational friction and supports radial and axial loads. Also, it improves the efficiency of mechanical power transmission and is commonly used in light industrial machinery. A basic ball bearing comprises four components: a ball, an inner ring, an outer ring, and a cage or retainer. The balls and rings are typically made of high chromium steel.

Numerous FAG tapered roller bearing series are available in X-life quality. In order to fulfill the requirements of X-life, the geometry, surfaces, dimensional and running accuracy, and the material and heat treatment process were all optimized. FAG tapered roller bearings in X-life quality increase the overall efficiency of your machines and equipment.

Cylindrical roller bearing

The bearing size and attributes are identified using a standardized numbering code system developed by ABMA. However, at Runsom Precision, we can manufacture non-standard bearings with unique characteristics through our custom CNC machining services.

FAG tapered roller bearings can support high radial and axial loads. They have a broad range of speeds. They are efficient at supporting forces and ensure a precise and rigid shaft guidance system due to the large effective distance between the bearings. Tapered roller bearings can be adjusted and dismantled, which makes mounting easy.

When selecting a bearing, it’s essential to verify its load and speed ratings to confirm that it can handle the anticipated loads and rotational speeds in your specific application.

This article presented ball bearing size charts that are commonly used. In addition, it offers guidance on how to define, interpret, and measure ball bearings.

Ball bearings endure both radial and axial loads during operation. Load ratings listed in the size chart represent the maximum capacity a bearing can withstand without encountering premature failure.

The speed ratings establish the highest rotational speed at which a bearing can function without generating excessive heat or experiencing premature wear.

When considering bearing performance, take into account clearance and tolerance. These factors can significantly influence the functionality of the overall system, so it’s vital to ensure that they’re appropriate for your applications.

Ball bearing

Ball bearings are essential components used in a multitude of machinery and mechanical systems, allowing for smooth and efficient rotational motion and minimum friction and wear. These devices comprise an outer and inner ring with a set of balls in between.

Four-row tapered roller bearings are used in rolling mills for the steel and non-ferrous industry sectors. These bearings are designed for extremely high radial and axial loads as well as for high speeds and impact loads and are used in extremely unfavorable ambient conditions such as high temperatures, water and contamination. With the new Performance series for rolling mills, costs can be significantly reduced from a TCO perspective.

The series number of a bearing can be found directly on the bearing and corresponds to a specific combination of measurements. To determine the measurements of a particular bearing, ball bearing size charts are readily accessible. The commonly used series are 6200 and 6300, which typically encompass sizes ranging from 10 x 30 x 9 mm (.394 x 1.181 x .354 in) to 150 x 320 x 65 mm (5.906 x 12.598 x 2.559 in).

Ball bearings come in various sizes based on the shaft size and the requirements of the application. Due to their usage in different industries, they are needed for a wide range of applications, from oil drills to skateboard wheels. How are these bearing sizes determined? How can we understand the ball bearing size chart?

To find the correct bearing match or replacement, it is essential to consider other significant aspects of the bearing number. Pay attention to the suffix, which provides additional details about the bearing design and features:

When measuring bearings, their inner diameter, outer diameter, and width are taken into account. The size of a bearing is typically indicated as ID x OD x W and is usually expressed in millimeters but can be converted to inches. Actually, most manufacturers and suppliers provide bearing measurements in both imperial and metric units.

The internal gap between the balls and raceways of a bearing is known as bearing clearance. This clearance affects the axial and radial play of the bearing and also influences its thermal expansion characteristics.

In these bearings, the raceways have optimized roughness and geometrical accuracy. This gives a higher load-carrying capacity and longer service life. X-life is the premium brand that identifies particularly high-performance products under the INA and FAG brands.

Single-row tapered roller bearings accommodate radial and axial loads (in one direction). For technical reasons, they are always positioned against a second tapered roller bearing in a mirror arrangement.

Schaeffler offers rigid axial tapered roller bearings that can accommodate very high axial loads and impact loads while requiring minimal axial installation space. They are manufactured as both single and double-direction bearings. Schaeffler also makes full-complement axial tapered roller bearings for pressure spindles in roll stands. Depending on the application in question, Schaeffler offers different variants (steel or brass cage)

The size chart includes crucial measurements, including the inner diameter (bore diameter), outer diameter, and width of the bearing. These dimensions are crucial in establishing whether the bearing is compatible with the intended shaft and housing.

Double-row tapered roller bearings accommodate radial and axial loads (in both directions) and are available in metric or inch sizes. The axial play of the bearing pair is determined during bearing production. There are numerous applications in industry and in the automotive sector.

The size of a ball bearing is determined by the shaft size and the specific requirements of the application, which has a significant impact on its performance and capabilities. Consequently, different industries utilize various sizes of ball bearings to meet their specific needs.

Needle bearing

Ball bearings allow for smooth and efficient rotational motion and minimum friction and wear in various machinery and mechanical systems. They consist of ball rollers positioned between the inner and outer steel rings to withstand larger loads.

After prolonged use, it’s not unusual for the bearing identification number to become illegible or worn out. In such cases, manual measurement of the bearing becomes necessary. Accurate measurements can be obtained using a vernier caliper. In the absence of a vernier caliper, measurements can still be taken carefully using a ruler.

The ball bearing size chart offers a comprehensive reference guide to a wide range of dimensions and specifications for ball bearings.

To make the proper selection for your application, it is crucial to have a clear understanding of the bearing size chart.

In general, ball bearings are smaller, load capacities are weaker. In such cases, small ball bearings are better suited for applications where space efficiency is prioritized over overload capacity. Precision miniature bearings are frequently used in incredibly small applications, including robotics, medical instruments, and semiconductor equipment. Conversely, larger bearings are designed to handle heavier loads, making them ideal for industries such as agriculture, mining, drilling, and heavy power tools. Some manufacturers such as Runsom Precision even offer custom bearing sizes tailored to the unique requirements of specific applications.

They are characterized by a longer rating and operating life – the result of higher dynamic load ratings than those of current standard products. If the load and design envelope are unchanged, X-life bearings have a longer rating life. Longer maintenance intervals are possible.

Ensure that the dimensions of the bearings align with the specific requirements of your shaft and housing. Confirm that the bore diameter, outer diameter, and width correspond to the specifications of your machinery.

To properly identify your needs, assess the operational conditions and performance requirements of your application. This includes factors such as load, speed, temperature, and the surrounding environment.
