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 guiding lateral cap is manufactured in plastic alloy, which is very resistant to wear and damaging outer agents.
Adjustable combined bearings with plastic cap have the following technical characteristics:
The outer ring is made in case-
The inner ring is made in core-
THE BEARINGS ARE IN ZRS EXECUTION
The adjusting of dimension “A” can be made through the rotation of the screw inserted in the pivot.
Technical Characteristics
Adjustable combined bearings with cap made in plastic material maintain high resistance to the load applied on them, and at the same time have an easy system of adjusting the distance between profile and bearing. The adjusting is made through the shifting of a screw which is put in the core of the pivot and lays on the cap.
