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.

A linear recirculating roller bearing assembly, which comprises:
- a bearing body having a load bearing surface and a return surface defining a path for continuous recirculating movement of rollers thereabout;
- an endless roller chain mounted on the bearing body, the roller chain including a plurality of pins arranged in a spaced, parallel relationship, and link members connecting the axial ends of adjacent pins together;
- and
- means to minimize skewing include a plurality of rollers mounted on the chain and disposed about the path in engagement with the bearing body surfaces, each roller being mounted on a corresponding pin of the chain and including at least two roller components rotatably mounted on the same pin co-axially to each other, each roller component being rotatable independently of the other components on the same pin.
