Standard External Circlips Diagram

circlip external heavy duty

The most common form of axially fitted circlips for shafts with grooves.

Constructed as curved beams of uniform strength, the radial width is reduced towards the free ends so that a constantly round shape is maintained throughout continuous use. This form of circlip often used in assemblies subjected to strong centrifugal forces, is also secure against high rotational speeds. Lugs with holes are provided for rapid fitting or removal with circlip pliers.

Standard material: Carbon Spring Steel – Standard Finish: Phosphate and Oil.
(Standard circlips are also available in Stainless Steel)
