Technical Characteristics - Adjustable combined bearings with steel cap

As for the previous series, adjustable combined bearings with steel cap maintain a very high resistance to applied loads, and at the same time, they have an easy system of axial adjusting.

Also in this case, the adjusting is made through the shifting of a central screw laid  on the cap.

In comparison to the adjustable execution with plastic cap, this execution can bear much higher axial loads, and therefore its wear is definitely lower.

Adjustable combined bearings with steel cap have the following technical characteristics:
  • The outer ring is made in case-hardening steel type 20 CrMnTi. It guarantees high resistance to stress and against crashes. Surface hardness reaches 60-2 HRC.
  • The inner ring is manufactured in 60-2 HRC core-hardening 100 Cr6 steel. Total-hardening steel guarantees high resistance to wear and stress.
  • 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-hardening steel as well.
  • The central pivot is made in low carbon C20/C45 steel, which guarantees high resistance and is highly suitable for welding.
  • Lateral guiding cap is manufactured in case-hardening 20 CrMnTi steel. It guarantees a very high resistance to stress and crashes. Surface hardness reaches 60-2 HRC.
