Hybrid roller bearings with single and double rollers have been proving their worth in the drylin® W linear modular kit for years with smooth manual linear adjustments.
By popular demand, the complete range of WJRM hybrid roller bearings will be expanded to include the ball bearing BB version. Due to the halved coefficient of friction, the WJRM-BB becomes the best smooth running linear bearing in drylin® W linear technology.
