GOST 13942-86 External locking ring

A circlip in accordance with GOST 13942-86 is an eccentric fastener used on a shaft or in a bore. This element 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 of GOST 13942-86

     GOST 13942-86 is made mainly of stainless steel and belongs to the group of stainless fasteners.

Materials of manufacture:

   The retaining ring of GOST 13942-86 is made mainly of:

• Steel, which can be additionally coated with zinc plating
• Stainless steel A2, as well as grade 1.4532 (austenitic)   

Scope of application of circlips of GOST 13942-86
     A circlip in accordance with GOST 13942-86 is a fastener that has a rather narrow scope of application. Its main areas of application are areas where there are structures with shafts. 

     For example:

• Mechanical engineering
• Automotive industry
• Instrumentation industry
• Construction.

     The most common use is in the automotive industry. GOST 13942-86 is indispensable both when repairing an engine with bearings and when installing bearings in various modifications. They are mounted in a groove for more reliable fixation of bearing elements and eliminate defects in the profiling of the cage. GOST 13942-86 limits the mobility of bearings on the axis.

     The scope of GOST 13942-86 also directly depends on the material of the fastener:

• Zinc-coated steel is less susceptible to corrosion if GOST 13942-86 is to be used in an aggressive environment.
• Stainless steel. Steel grade A2 allows the use of GOST 13942-86 at significant temperature drops and in aggressive and humid environments.
