Our external stainless steel snap ring that there is no interference in assembly and inner ear diameter burrfree, you can manually and automatic quick installation and removal, generally die stamping circlip have ears to interfere in assembly, internal diameter will produce burrs and difficult to install.
An external stainless steel snap ring is a type of retaining ring installed on a groove or shaft to fix the axial movement of the component. The outer or inner diameter of this type of retaining ring is slightly larger or smaller than the mounting hole or shaft diameter. The circlip pliers must be used to expand or contract the circlip during installation before placing the circlip into the pre-machined shaft groove.
External stainless steel snap ring production materials are: S stainless steel US304; SUS316 as the core. The commonly used material is 65Mn spring steel, which is used in occasions with low requirements for rust prevention or high oil content.
External stainless steel snap rings are the most widely used carbon spring steel. Compared with 65 steel, it has higher strength, hardness, elasticity and hardenability. The critical hardening diameter is generally 30-50mm in water and 16-32mm in oil. Therefore, the stainless steel retaining ring material ensures its good performance and meets people’s needs.
The external stainless steel snap ring can be said to be a standard part or not a standard part. It is said to be a standard part because some products have lower requirements. As long as the inner and outer diameters of the retaining ring are almost suitable, it can be used for improvisation. It is not a standard part because many products have clear requirements for assembly parameters, such as the inner and outer diameter and thickness required for assembly, bearing strength, etc. At this time, they need to be specially customized according to the requirements.
