WD Support Rollers | Support Roller Bearings | WD Bearing Group -> Bearings for Material Handling System

Features

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.

Applications of WD support rollers:

1) Automotive equipments;
2) Material handling equipments;
3) Mining & metals equipments;
4) Linear motion guide equipment;

Advantages of WD support rollers:

1) Optimized structure and reliable quality;
2) Modifying the contacting surface logarithmically to reduce the contact stress;
3) Used in wide range with different precision standards;
4) Reducing the fitting and maintaining costs with the ready-to-fit units;
5) Special oil supplying system and easily operating;
6) With thick-walled outer and can take up high radial load especially;
7) With axial guidance, support rollers can bear the axial impact load even at high speed;
