Four-point contact ball bearings

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 …

Design of Four Contact-Point Slewing Bearing With a New Load Distribution Procedure to Account for Structural Stiffness …

1/2/2010· This paper proposes a procedure,for obtaining the load distribution in a four contact-point slewing bearing considering the effect of the structure''s elasticity. The uneven stiffness of the rings and the supporting structures creates a variation with respect to the results obtained with a rigid model. It is necessary to evaluate the effect of the elasticity on the increase in the …

Four point contact ball bearing stiffness

Four Point Contact Ball Bearing Stiffness. The stiffness of a rolling-element bearing is one of the main contributors to the transmission of force from the exterior loading to the slewing ring bearing itself. Many methods have been proposed to determine the bearing stiffness. The very compact design of a four-point contact ball bearing may lead
