Salient Features of External Circlips :
• They may be used to replace nuts, threaded sleeves, cotter pin, rivets, set collars, machined shoulders and many bulkier and more expensive fastening devices.
• As circlips are installed in pre-cut grooves, these pre-cut grooves can often be machined simultaneously with other production process; they eliminate threading, tapping, drilling, and other costly machining operations.
• Speed of assembly and disassembly further reduces manufacturing costs.
• Space saving, compared to contemporary methods.
• Reduces assembly weight.
• Longer service life.
Material of External Circlips :
All the Circlips are manufactured from spring steel of grade such as 70C6 or 75C6 confirming to IS: 2507 - 1975 specification for cold rolled steel strips for springs (first revision).
Surface Finish of External Circlips :
Unless the purchaser specifies any alternative finish, the circlip shall be chemically or thermally blackened.
All circlips are thoroughly inspected for parameters like circlips thickness, internal diameter, conical deformation, spiral flatness, hardness and function like set and grip.
