Internal Circlip as per DIN 472 standard, designed for fitting into bores or housings to secure components against axial movement. Made from hardened spring steel for high strength, precision fit, and long service life in demanding mechanical applications.
Internal Circlips (DIN 472) are precision retaining rings designed to be installed inside cylindrical bores or housings to restrict the movement of shafts, bearings, or other assembled parts. They provide an efficient axial locking mechanism that eliminates the need for additional fasteners.
Manufactured from high-carbon or stainless spring steel, these circlips are heat-treated for superior elasticity and fatigue strength, ensuring consistent performance under vibration and load conditions. The ring’s lugs feature precision holes for easy fitting and removal with standard circlip pliers.
Compliant with DIN 472 / ISO 8749 standards, internal circlips are widely used in automotive assemblies, gearboxes, valves, and industrial machinery.
