Four Point Contact Bearings | Schaeffler Germany
Four-point contact bearings are single-row angular contact ball bearings and therefore require significantly less space in an axial direction than double-row designs. The bearings comprise solid outer rings, split inner rings and ball and cage asselies with brass or polyamide cages.
Preload, clearance, and stiffness | SKF
Preload, clearance, and stiffness. A single super-precision angular contact ball bearing cannot be preloaded until a second bearing provides loion in the opposite direction. Bearings manufactured pre-set for preload. Universally matchable bearings and matched bearing sets are manufactured pre-set in different preload classes to meet varying
Four Point Contact Bearings - Bright Hub Engineering
22/4/2009· Four point contact bearings are single row angular contact bearings having a slight change in the construction compared to the angular contact bearing. This type of bearing normally tends to have contact at four points i.e. two in the outer race and two in the inner race. The four point contact bearing has some advantages over the other kinds
1.TYPES AND FEATURES OF ROLLING BEARINGS
Ball Bearings The inner and outer rings of four-point contact ball bearings are separable because the inner ring is split in a radial plane. They can take axial loads from either direction. The balls have a contact angle of 35 with each ring. Just one bearing of this

Reali-Slim® type X four-point contact thin section bearings | …
The Reali-Slim® type X four-point contact ball bearing is distinguished from types A and C by the geometry of its ball grooves. In type C bearings, the centers of the radii both lie in the plane of the ball centers. In type A bearings, the races and balls are in angular contact, and the centers of the groove radii are offset equal amounts on
Four point contact bearings | Schaeffler medias
Four point contact bearings are single row, non self-retaining radial ball bearings. They are similar in their structure to single row radial angular contact ball bearings; the raceways on the inner rings are, however, designed such that they can …
Kaydon Bearing | KB035XP0 | Reali-Slim® Four-Point Contact Bearing | Applied
Standard bearing lines are most often designed to handle either radial or axial load conditions. The unique feature about the Kaydon Reali-Slim Type X four-point contact bearing line is that the gothic arch geometry of the inner and outer races enables a single bearing to carry three types of loading (radial, axial and moment) simultaneously.
