   Internal Circlips

 
Internal Circlips
Outer Diameter
8mm to 500mm

Thickness
0.4mm to 6mm
 
Salient Features of
Internal Circlips :
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
Internal 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
Internal Circlips :

Unless the purchaser specifies any alternative finish, the circlips shall be chemically or thermally blackened.

Quality Assurance:
All circlips are thoroughly inspected for parameters like circlips thickness, internal diameter, conical deformation, spiral flatness, hardness and function like set and grip.
