These bearings are normally supplied with seals in ZZ execution. They can also be manufactured in 2RS execution on request. All the bearings of this series are provided with a lubrication system both for the radial and the axial part.
The thrust ring is made of cementation steel.
The central pivot is made of 16CrNi4 cementation steel which guarantees a high resistance to stress and a good welding.
Adjustable combined bearings for heavy industry have the following features:
The outer ring and the axial little roll are made of the best possible 18NiCrMo5
cementation steel. The surface hardness is 60-
The inner ring and little pin are made of core hardened 100Cr6 with hardness 60+2 HRC.
THE BEARINGS ARE IN ZZ EXECUTION, THEY CAN BE EXECUTED IN 2RS ON REQUEST.
The adjusting of “A” size is made through washer rings put between the main support
roll and the lateral guide bearing. Adjusting washers with 0,3-
The bearings are supplied with lubrication holes.
