Conveyor Track Rollers

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.Yoke type track rollers can support high radial loads and axial loads arising from misalignments and skewed running and are suitable for cam drives, slideways, conveying equipment etc. The bearings are available with or without an inner ring as well as in open and sealed versions.

Track rollers are self-retaining, single or double row units with particularly thick-walled outer rings. These bearings can support axial forces in both directions as well as high radial forces. The bearing outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where there is misalignment in relation to the raceway and edge stresses must be avoided. The track rollers are available with an inner ring, with a stud and with a plastic tyre on the outer ring.
