Load Ratings - Bearing Works

Basic Static Load Rating for stainless steel is 75 80% of that for standard bearing steel. Basic Dynamic Load Rating The basic dynamic load rating (Cr) of a bearing with rotating inner ring and stationary outer ring is that load of constant direction and magnitude which a sufficiently large sample group of apparently identical bearings can endure for a basic rating life of one million …

Radial Internal Clearance - Bearing Works

Radial Internal Clearance. Internal clearance is the play within a ball bearing. It is the geometrical clearance between the inner ring, outer ring and ball. It is a critical factor in bearing selection that will directly impact bearing life. It is often overlooked, particularly as to how it is reduced by interference fits.

Technical Information: Ball bearing types, selection factors, and …

Ball Bearings. There are several types of ball bearings that fit specific needs. The deep-groove ball bearing, Figure 2 (a), is the most versatile. Radial loads and thrust-load capacities may be approximately equal in this bearing. When it has the proper separator, it is very good for high-speed operation.

Ball bearing - Wikipedia

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most

Radial Ball Bearing Life & Load Ratings | AST Bearings

Dynamic load ratings are determined by bearing geometry, nuer and size of balls, bearing pitch diameter, and ring and ball material. This load rating is used in conjunction with the actual applied radial load to calculate bearing fatigue life. The static load rating relates to limiting loads applied to non-rotating bearings.
