WD support rollers are basically needles or cylindrical roller bearings with a thick-walled outer race. The rollers are available either with a flat runner surface or crowned runner surface, which can be designed according to customer's application.
With this outer race, the support rollers are able to roll directly in the raceway and bear a heavy load rating. The crowned runner surface should always be used where angular misalignments with respect to the track expected and edge stresses kept to a minimum. They are ready-to-fit units, filled with grease and are suitable for all types of cam drives, tracks, conveyor systems and etc.
The support rollers can be divided into ones with axial guidance or without axial guidance. And from sealing structure, they can be divided into open type and sealed type.
