The circlip PN 85111 W is an eccentric fastener that is used on a shaft or in a bore. Visually, this part is a ring with free edges on which holes are placed for easy fixation inside the hole.
It prevents spontaneous displacement of the mechanism elements relative to each other, which is especially important some time after installation. This increases the reliability of the structure.
Fastening group PN 85111 W
PN 85111 W is primarily made of stainless steel and belongs to the stainless steel fastener group.
Materials of manufacture:
The snap ring PN 85111 W is made primarily of:
- Steel, which can be additionally coated with zinc plating.
- Stainless steel A2, as well as 1.4532 (austenitic). This material does not require any additional treatments.
Selection of the locking inner ring
- The standard of the ring should be taken into account. If we compare PN 85111 W with its analogs, it is thicker.
- Its material should be selected taking into account the load and the environment in which it will be used.

Application of circlip PN 85111 W
The grooves for the circlip PN 85111 W are located in the housing, behind the seating surface of rolling bearings and other parts, so that the protruding part of the circlip fixes the part in the mounting location.
Snap rings are used in almost all areas where housing structures with shafts, bearings and other parts are used.
Speaking specifically about the areas of application, snap rings are most popular in:
- Automotive industry
- Machine tool building
- Mechanical engineering
Special tools are used to assemble and disassemble this fastener. However, small diameter circlips can be installed with a standard flathead screwdriver.
The scope of application of PN 85111 W also directly depends on the material of this fastener:
- Zinc-coated steel is less susceptible to corrosion when PN 85111 W is used in aggressive environments.
- Stainless steel.Steel grade A2 allows for the use of PN 85111 W at high temperature extremes and in aggressive and humid environments. This material does not require a coating.
