Abstract
Abstract A bearing unit for supporting or riding on a linear member, which is held between multiple rollers mounted in a housing through which the linear member passes. The rollers are rotatable about axes substantially perpendicular to the longitudinal axis of the linear member, and in one form of the unit the rollers are radially adjustable to accommodate linear members of various sizes. For simplicity of manufacture and assembly, the housing is made in two similar halves, which are secured together to contain the rollers.
