Product Introduction

A circlip (retaining ring) is an elastic retaining ring used for positioning and fixing parts on shafts or in bores. It snaps into a groove by its own elasticity, providing axial retention to prevent parts from moving or falling off during operation.

WT Fasteners specializes in producing various types of circlips, including external circlips for shafts, internal circlips for bores, and more. We can provide different materials, specifications, and surface treatments according to customer requirements. Our products are widely used in automotive, machinery, motors, gearboxes, and industrial equipment.


Product Features

1. Reliable Axial Retention

Circlips are installed in shaft or bore grooves to effectively limit axial movement of parts, enhancing mechanical stability.

2. Made of High-Quality Spring Steel

Manufactured from high-quality spring steel, stainless steel, and other materials, offering excellent elasticity, fatigue resistance, and long service life.

3. Precision Machining

Strict control of dimensional tolerances ensures precise fit between the circlip and the mounting groove, facilitating easy installation and removal.

4. Multiple Specifications Available

We offer standard specifications and non-standard customization services, and can produce according to customer drawings or samples.
