Internal Retaining Rings – Secure & Reliable Internal Shaft Retention
Product Description
Internal Retaining Rings, also known as Internal Circlips, are essential fasteners used to hold components securely within a bore or housing. These rings are installed into a groove inside a cylindrical hole to create a secure shoulder that prevents lateral movement of parts such as gears, bearings, and pins.
Manufactured in compliance with DIN 472, IS 3075, and SAE J895 standards, our rings ensure high precision, strength, and durability, even under high RPM or load conditions. Available in various materials and surface finishes to suit different operating environments.
Applications
Internal Retaining Rings are commonly used in:
Automotive Transmissions & Wheel Hubs
Hydraulic & Pneumatic Cylinders
Electric Motors & Gear Systems
Medical Devices and Instrumentation
Bearing Assemblies in Pumps and Compressors
