Standard External Circlips - High Grade Steel, Precision-engineered Fasteners For Reliable Assembly And Retention, Ensures Smooth Operation, Longer Service Life

Circlips - External

Introduction

External 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 on shafts, studs and similar parts. 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

• 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 weight.
  

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.
