The internal structural design of rollers is given by deep groove ball bearings or double row angular contact ball bearings so as to make them withstand higher loads.
Rollers are made using high quality heat treated bearing steel. They are filled with high grade and multi-purpose grease for longer service life. Rollers are made dust proof with a metal shield or rubber seal.
