Abstract: A bearing assembly mounted on a shaft provided with one or more ball conforming grooves, the bearing assembly including a bearing retainer sleeve supporting one or more ball retainers that provide recirculating ball bearing raceways, each raceway having a load-free portion and a load-bearing portion adjacent a grooved load-carrying plate, with each load-carrying plate corresponding to a shaft groove being mounted in the retainer so as to be capable of reorienting itself about the line of balls under loading between such load-carrying plate and its corresponding shaft groove.

Abstract: A self-contained linear bearing unit presenting a single line of bearing support therewith is comprised of a retainer having ball-loaded paths and ball-unloaded paths with turnaround paths being located in end sections of the retainer. Caps received on the end sections capture the ball bearings and a bearing plate is disposed over the balls in the ball-loaded path. The unit can be made in a linked together chain of such units and various bearing configurations can be formed from plural ones of such units arranged in a desired disposition.

Abstract: A split roller bearing assembly includes a bearing body, an endless roller bearing chain mounted on the bearing body, and a plurality of rollers mounted on the chain. The bearing body has a load bearing surface and a return surface which define a path for continuous recirculating movement of the rollers thereabout. The roller bearing chain includes a plurality of pins arranged in a spaced, parallel relationship, and link members connecting the axial ends of adjacent pins together. Each roller is mounted on a corresponding pin of the chain, and is split to define at least two roller components rotatably mounted co-axially to each other on the same pin. Each roller component is rotatable independently of the other roller component of the same pin.

Abstract: A combination linear and rotary anti-friction bearing. The bearing includes a casing within which is mounted a plurality of oblong tracks containing anti-friction balls adapted to engage a shaft and load bearing plates. Assembled to the casing at each terminal end thereof are rotary anti-friction balls mounted between outer and inner cylindrical raceway members so as to provide a linear and rotary bearing. The outer cylindrical members have a diameter slightly larger than the outer diameter of the casing.

Abstract: A ball bearing for linear motion which is particularly useful in applications where the "open type" ball bearing is in combination with a shaft supported along its length which is subjected to radial forces primarily toward or away from the open side of the bearing.The ball bearing for linear motion consists of a bearing sleeve adapted to position a plurality of bearing segments on its inside surface. Each bearing segment contains a closed loop of circulating balls. The closed loop has one straight track of load bearing balls and one straight track of non-load bearing balls. The bearing segments are circumferentially positioned within the bearing sleeve so as to maximize the capacity of the bearing when load is applied either toward or away from the open side of the bearing.
