Bearing rings and balls are not perfectly round and the balls and raceways, even after extensive fine grinding and polishing, are not perfectly smooth. There are machining imperfections in the form of rough or uneven surfaces which will cause one ring to move or oscillate radially in relation to the other causing bearing vibration and noise.

Radial play (internal clearance) in ball bearings Pt. 1 - Bearing Tips

26/3/2018· Radial play, or internal clearance, is the internal radial looseness in a bearing and is the measured value of the total radial movement of the outer ring with respect to the inner ring in a plane perpendicular to the bearing axis. Ball bearings are asseled to radial play values depending upon the desired range.

Bearing Contact Angle Calculations - GMN Bearing USA

As the balls rotate, they produce a centrifugal force that causes them to push radially outward and move up the bearing raceway. This decreases the contact angle of the outer race because the ball moves in the direction of the radial axis but increases the inner race contact angle as the ball moves up and away from the radial axis.

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
