External Retaining Rings – External Shaft Security with Precision
Product Description
External Retaining Rings, also known as External Circlips, are specially designed fasteners that fit over shafts into pre-machined grooves. Once installed, they create a rigid shoulder that holds assemblies such as gears, bearings, or pulleys firmly in place. These rings are ideal for axial retention where high rotation speeds or vibrations are common.
SM Fasteners manufactures these components in strict compliance with DIN 471, IS 3075, and SAE J496 standards, ensuring they meet the performance expectations of precision industries globally. With high spring tension and fatigue resistance, our rings deliver long-lasting performance even in harsh environments.
Applications
External Circlips are widely used in:
Automotive Shafts, Gearboxes & Drive Systems
Hydraulic Pumps & Cylinders
Electric Motors & Fans
Precision Instruments & Bearings
Aerospace Engine Assemblies
Industrial Robotics & Actuators
