Track Rollers SG20 SG20-2RS Bearing

SG20 SG20-2RS locating bearing track rollers with Gothic arch groove. 

•  There are two contact points between the roller and track, so the contact function is favorable.
•  Rollers feature double row angular contact ball bearing in its internal structure design and a thick-walled outer ring, so rollers can accommodate higher loads.
•  Rollers are made of high-quality bearing steel, processed by heat treatment and precision grind, and are filled with a long service life, high-grade and multi-purposes grease. Rollers mount the rubble seal (2RS) to prevent the dust. Some types of the rollers can be made from the corrosion resistance stainless steel 440C.
