Circlip Internal Stainless Steel 10mm - Pack of 5

Internal circlips (also called internal retaining rings or snap rings) are precision-formed rings that seat into a machined groove inside a bore or housing, holding bearings, bushes, gears, shafts and other components securely in place. Available here in 304 grade stainless steel to DIN 472, they resist corrosion in washdown, marine, food-processing and outdoor environments where a plated or carbon-steel circlip would rust.

Where this product is used

Internal circlips are used wherever a component needs to be retained inside a bore or housing without welding, bolting or machining a shoulder — the ring seats into a machined internal groove and holds the component captive from the inside.

• Bearing, bush and gear retention inside housing bores in pumps, gearboxes, electric motors and general mechanical assemblies.
• Food, beverage and dairy processing equipment, where wash-down and hygiene requirements call for a stainless rather than plated-steel circlip.
• Marine and chemical plant machinery, and other outdoor or wet-environment equipment where corrosion resistance is essential.

Key specifications

Selecting the right option

Confirm internal vs external before ordering — an internal circlip (this product) fits inside a bore or housing; an external circlip fits around a shaft. Match the circlip to the exact bore diameter for your application and check it against the machined groove dimensions in your equipment drawings or the manufacturer's spec sheet. Choose 304 stainless steel where the application involves washdown, marine, food-grade or outdoor corrosion exposure; standard carbon steel is a lower-cost option for dry, indoor, low-corrosion environments.
