Dimensions of a ball bearing
Ball bearings come in various dimensions depending on their type and intended use. Here are the typical dimensions provided for a ball bearing:
1. Bearing Series: Ball bearings are often categorized into series based on their dimensions and load capacities. Common series include the 6000 series, 6200 series, 6300 series, etc. Each series has its own range of inner diameter, outer diameter, and width dimensions.
2. Seals and Shields: In addition to the basic dimensions, ball bearings may also feature seals or shields to protect against contaminants and retain lubrication. These additional features may slightly affect the overall dimensions of the bearing.
3. Tolerance Classes: Bearings are manufactured to specific tolerance classes, which define the allowable deviations in dimensions. Common tolerance classes include P0 (normal), P6 (higher precision), P5 (even higher precision), and P4 (very high precision).
4. Radial Clearance: Radial clearance refers to the internal clearance within the bearing, which affects its ability to accommodate thermal expansion and shaft deflection. Bearings are available with various levels of radial clearance, denoted by C0, C2, C3, etc.
5. Cage Type: Ball bearings may have different cage designs, such as steel cages, brass cages, or polymer cages. The cage type can impact the overall dimensions and performance characteristics of the bearing.
6. Width (W): This refers to the thickness of the bearing, measured from one side to the other. It’s also measured in millimeters (mm).
For example, a common ball bearing might have dimensions such as:
– Inner Diameter (ID): 10 mm
– Outer Diameter (OD): 30 mm
– Width (W): 9 mm
7. Bearing Material: Ball bearings can be made from various materials, including stainless steel, chrome steel, and ceramic. The material composition can impact the bearing’s performance, longevity, and resistance to corrosion or high temperatures.
8. Axial Load Capacity: While dimensions primarily relate to the size of the bearing, the axial load capacity is also an important consideration. It indicates the maximum axial load that the bearing can withstand without excessive deformation or failure.
9. Outer Diameter (OD): This refers to the diameter of the outer ring of the bearing. It’s measured in millimeters (mm).
10. Inner Diameter (ID): This refers to the diameter of the bore or inner ring of the bearing, where the shaft rotates. It’s measured in millimeters (mm).
These additional factors further characterize the dimensions and capabilities of ball bearings, helping engineers and users select the most suitable bearings for their specific applications.
