We design and manufacture a wide range of circlips. Used as a fastener, these products are semi-flexible metal ring that comes with open ends. We offer both the types of circlips that are internal and external. The different kinds of circlips offered by us can vary in terms of dimensions and type of raw materials used. We also manufacturer and supply Snap Ring and Horse Clamp.
External Circlip (Light Series)DIN : 471 IS : 3075
External Circlip (Heavy Series)
- Alternate Shape of Lug For d1=40 and above
- Expanded for Assembly
Covers the requirement of circlips for shafts of nominal diameter range 3 to 300 mm in normal type and 15 to 100 mm in heavy type.
Material and Hardness
The circlips shall be manufactured from spring steel of grade EN42J and stainless steel in 304 and 316 as per DIN : 471 & IS: 3075.
Hardness of circlips shall be given below:
|Nominal Diameter Of Circlips||Hardness|
|-||48||470 to 580 Vickers Hardness (Corresponding to 47 to 54 Rockwell C hardness)|
|48||200||435 to 350 Vickers Hardness (Corresponding to 44 to 51 Rockwell C hardness)|
|200||300||390 to 470 Vickers Hardness (Corresponding to 40 to 47 Rockwell C hardness)|
All sharp edges shall be removed from the circlips. The circlips shall be free from burrs, cracks, laminations and other defects.
The maximum permissible deviation on the profile at engaging lip may also be mutually agreed upon between the manufacturer and the user in case of special application.
Unless any alternative finish is specified by the purchaser, the circlips shall be chemically and/or thermally blackened or phosphate to class A2 of IS: 3618-1966 ‘Phosphate treatment for iron and steel for protection against corrosion’. The coated circlips shall be subjected to appropriate treatment to avoid hydrogen embrittlement.
