These rollers are normally used as lifting devices in the lift trucks masts.
 Characteristic of these bearings is to have the outer ring shaped in such a way to contain sideways the Fleyer pull chains. They are full complement cylindrical rollers bearings and they can take very high radial loads.
 The axial loads arising from the chain guides are easily supported thanks to the correct coupling of the heads of the cylindrical rollers used in the bearings with the ground lateral surfaces of the rings.
 This rolling system grants high safety and reliability even under very hard working conditions.
 The bearings of this series are available only in sealed execution, long life lubricated and therefore supplied grease filled.
 They can be mounted both in protrusion on the lifting cylinders’ heads and between the two lateral supports.
 For this type of mounting it is recommended to keep low axial clearances (max. 0,5 mm) to avoid an incorrect running of the rolling elements.
