Roller Bearings vs. Ball Bearings - What''s the Difference?

Ball bearings are described as having point contact; that is, each ball contacts the race in a very small patch – a point, in theory. Bearings are designed such that the slight deformation the ball makes as it rolls into and out of the load zone does not exceed the yield point of the material; the unloaded ball springs back to its original shape.

How to properly mount thin section bearings: a new Kaydon

Four-point contact (Type X) bearings. Four-point contact bearings are used when there is a thrust load or some coination of radial, thrust and moment loads (see Figure 2). If two bearings are used on the opposite ends of a long shaft, the second bearing should be a radial (Type C) bearing, and it should be allowed to float as shown in Figure 1.

QJ208-XL-TVP Four-point contact bearing: Schaeffler medias

Technical information on Four point contact bearings. Four point contact bearings are particularly suitable where: Predominantly axial loads must be supported; The axial design envelope is not sufficient for double row radial angular contact ball bearings; Radial forces must be supported by a separate radial bearing

What Are Ball Bearings Used For?

Aug 01, 2014· A bearing that is used to support a bar stool is an example of a bearing that is subject only to thrust load. Ball bearings work by transferring the load from the outer race to the ball and on to the inner race. Everything is able to spin smoothly since the spherical shape of the ball only touches the inner and outer race at very small points.

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.

Linear Bearing: What Is It? How Does It Work? Uses, Types

This causes a ball to have different rolling speeds in its contact diameters, making it slip as it rolls. To overcome this, a larger force is required to drive the ball bearing. Circular Arc Profile. In a circular arc profile, the ball makes two contact points on the raceway; one contact point each for the bearing and guide rail grooves.

Ball Bearings: Guide to selection, appliions

XF r + YF a (3 for ball bearings and 10/3 for roller bearings) ( X = 1 and Y = 0 always). X and Y are factors required for the calculation of equivalent dynamic bearing load for single and double row deep groove ball bearing, dependent upon axial load (Fa) and radial load (Fr). Therefore, if P o < F r, P = P o = F r.
