Turntable Bearings for industrial appliions

Turntable bearings (sometimes referred to as slewing ring bearings) are 4 point contact thin section type ball bearings that have holes in both the inner and outer rings for easy mounting. These products were designed from standard thin section bearing geometry. We just reduced the ID and increase the OD to accommondate bolt holes.

Types of Bearings | Uses & Working Mechanisms Explained

25/8/2020· Ball bearings provide very low friction during rolling but have limited load-carrying capacity. This is because of the small area of contact between the balls and the races. They can support axial loads in two directions besides radial loads. Ball bearings are used for controlling oscillatory and rotational motion.

Angular Contact Ball Bearings - an overview | ScienceDirect Topics

In Fig. 4.6a is shown a single row radial thrust (angular contact) ball bearing. The contact angle a is the angle of the axis of contact between balls and races. For a single row radial ball bearing, the angle α is zero. If Fr is the radial force applied to the ball, then the normal force to be supported by the ball is.

Four-point contact ball bearings – two in one | Evolution

25/6/2015· A four-point contact ball bearing ( fig. 1) can accommodate axial loads in both directions, in coination with radial loads up to a certain level, and provides a very tight axial shaft position tolerance. The bearing also saves space, because it can be seen as the coination of two single row angular contact ball bearings into one.

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.

Four-Point Contact Ball Bearings: inform yourself & order online …

Four point contact bearings are similar in their structure to double row angular contact ball bearings, but are considerably narrower in an axial direction due to only one raceway groove. Since the centres of curvature of the arc-shaped raceways on the inner ring and outer ring are offset relative to each other, the balls are in contact with the bearing rings at four points …
