Yoke Type Track Rollers - NUTR Series

Product Description

MBY track roller bearings include mast rollers and chain pulleys, and york type track rollers. They are essentially cylindrical roller or needle roller bearings which have a thick-walled outer race.
The pulleys are available with a flat runner surface or a crowned one, which can be designed according to customer’s application. They can roll directly on the tray under heavy load and shock load. They are greased for life. Under normal operating conditions, they are maintenance-free, while they should be re-lubricated under severe working condition to prolong the working lifespan.
