Internal circlips are retaining rings for securing mechanical elements (e.g. bearings) in bores.
Circlips are installed into a groove and creating a shoulder that retains the
assembly. Lugs with holes are provided for easy fitting and removal with pliers.
Metric internal circlip dimensions are shown in the following chart according to DIN 472 standard.
Some important notes from the DIN 472 standard:
- Material: C 67 , C 75 or Ck 75 spring steel in accordance with DIN 17222.
- Finish: Circlips must be without burr. Circlips are normally supplied corrosion-proof. Details are given in DIN 472.
- Designation: Bore diameter (nominal dimension) and circlip thickness s (Ex: Circlip DIN 472 - 40 x 1,75)
