2 Turn Internal stainless steel snap ring

Product Description

Double-layer internal stainless steel snap rings flattened steel wire spiral retaining ring for hole


Internal stainless steel snap rings have no ears in your assembly! Internal stainless steel snap rings are manufactured by coiling the ring from flat wire. This unique process produces a retaining ring that has no protruding ears or burrs to interfere with your assembly. Because coiling produces a retaining ring with no scrap, the Spiral Retaining Ring can be economically produced in carbon steel, stainless steel, coppers, and many other alloys.

No gap – 360 retaining surface.

No protruding ears interfere with mating components (uniform cross-section).

Economically produced in stainless steel because the coiling process produces no scrap.

No -Charge on custom designs.

Easy installation and removal.


Features of Lisheng internal stainless steel snap ring:

  1. The earless design of Lisheng retaining ring makes the retaining ring and accessories not interfere with each other;
  2. Lsheng retaining ring is wound and formed, and the mechanical properties are more stable compared with the traditional stamping process;
  3. 360° plane, dimensional stability;
  4. More than 5,000 standard retaining rings (diameter 6.5~406mm);
  5. There is no need to open the mold for special customized non-standard retaining rings (diameter 5~2300mm);
  6. Easy to install and disassemble.

The hole uses an elastic internal stainless steel snap ring, which is installed in the round hole and used for the axial movement of the fixed parts. The outer diameter of this kind of internal stainless steel snap ring is slightly larger than the diameter of the assembly round hole. The retaining ring is easy to assemble and disassemble by its own elasticity. When installing, it is necessary to use circlip pliers, insert the pliers nose into the pliers hole of the retaining ring, and clamp the retaining ring before placing it into the pre-machined inner groove of the round hole. Commonly used elastic internal stainless steel snap ring materials for shafts include 65Mn, SUS304 and SUS316.
