National standard for spiral retaining ring

The spiral retaining ring is a commonly used fastener, typically used to prevent loosening of nuts or bolts on bearings or mechanical parts. In China, the standard for spiral retaining ring is GB/T 94-1985 "Elastic Round retaining ring".

This standard specifies the requirements for the material, shape, size, mechanical properties, surface state, and inspection methods of resilient round lock washers. Specific requirements include the following:

Materials: The spiral retainer ring should be made of elastic materials with sufficient elasticity and corrosion resistance. Common materials include elastic steel, stainless steel, and so on. Mechanical properties: The spiral retaining ring should have sufficient resilience and fatigue life to ensure that it can effectively prevent loosening of the nut or bolt during use. layers.

Inspection method: The inspection of the spiral retainer ring should include multiple indicators such as appearance inspection, dimensional inspection, rebound force and distortion angle detection. Washer". Therefore, when using spiral retaining rings, it is recommended to use the new standard.
