These roller pulleys light series, are bearings, improperly called "pulleys" have the outer ring built with a shape suitable for the lateral containment of the "FLYER" traction chains, are normally used as lifting devices on the uprights of forklift trucks.

The bearings are built with full complement cylindrical rollers in order to be able to support very high radial loads.

The axial loads originating from the chain guide are supported by the correct coupling of the heads of the cylindrical rollers used in the bearings, with the ground side surfaces of the rings.

This rolling system is highly reliable even when extreme performance is required.
