Our 135mm External Circlip is a precision-engineered retaining ring manufactured to DIN 471 standards, designed specifically for securing components on a 135mm diameter shaft. Made from high-grade A2 Stainless Steel, this external circlip features a 128mm internal diameter and 4mm thickness, offering excellent mechanical strength and corrosion resistance in demanding environments. With a tang height of 11.8mm, it’s ideal for retaining bearings, gears, and other assemblies, ensuring reliable axial positioning and long-term durability in both static and dynamic applications.

What is an External Circlip?

An external circlip, also known as a shaft circlip or external retaining ring, is a type of fastener designed to snap into a machined groove on the outside of a cylindrical shaft. Its role is to act as a mechanical stop, preventing the lateral movement of components once installed. This 135mm external circlip is suitable for use on small-diameter shafts where space is limited, offering robust retention without the need for additional fixing hardware. As it’s manufactured from A2 Stainless Steel, it also resists rust and oxidation, making it ideal for use in environments exposed to moisture, chemicals, or temperature changes.
