Adjustable combined bearings have the same characteristics as fixed combined bearings.
The only difference is the possibility to adjust the distance between bearing and profile through the use of washers.

ZRS seal system, realized by C.R. during the recent years, prevents outer agents, such as dust, wet and mill scale, to enter the inner part of the bearing, and at the same time it prevents the leakage of lubrication grease.
The lateral thrust cover is made in case-
The central pivot is made in low carbon C20/C45 steel, which guarantees high resistance and is highly suitable for welding.
The support roll, which allows the adjusting of the axial clearance between profile and bearing through washers of 0,3 to 0,5 mm, is manufactured in 20 CrMo steel.
Adjustable combined bearings have the following technical characteristics:
The outer ring and the axial little roll are manufactured in case-
This kind of steel guarantees a very good resistance to stress, and assures a very
good resistance against crashes. The surface hardness can reach 60-
Inner ring and pin are manufactured in core-
THE BEARINGS ARE IN ZRS EXECUTION
The adjusting of dimension “A” is made through washer rings put between the main support roll and the support roll
of the lateral guide bearing. Adjusting washers are available with thickness 0,3-
