Features

Perfect finish
Sturdy design
Impact resistant

Introduction

Internal circlips are precision-engineered fasteners and are suitable for a wide variety of assemblies. They are designed to service as shoulders for accurately locating, retaining of locking components in bores. They are assembled in axial direction into pre-cut grooves, which assure precise locating of parts. They maintain constant pressure against the bottom of the groove and are secure against heavy thrust loads.

Salient Features

As circlips are installed in pre-cut grooves, these pre-cut grooves can often be machined simultaneously with 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.

Dimensions
For circlips of normal type, the dimensions, tolerances, and design data is given in Table1.

Material
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)

Hardness
The hardness of the circlips are kept according to the following chart.

Nominal Diameter of Circlips		Hardness
Over	Up to	Hrc
-	48	47 to 54
48	200	44 to 51
200	300	40 to 47

Finish
Unless the purchaser specifies any alternative finish, the circlip shall be chemically or thermally blackended.

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