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 thrust cover is manufactured in case-
The central pivot is made in low carbon C20/C45 steel, which guarantees high resistance and is highly suitable for welding.
Adjustable combined bearings with eccentric pin 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-
Technical Characteristics
Adjustable combined bearings with eccentric pin have the same characteristics as adjustable combined bearings.
In this case, the adjusting of the distance is made through the rotation of the whole axial part (pin and little roll) in the central pivot.
THE BEARINGS ARE IN ZRS EXECUTION
The adjusting of dimension “A” can be made through the rotation of the axial pivot.
