Circlip External - Heavy Duty 12 x 1.5mm

This heavy duty external circlip is a heavier-gauge external retaining ring that snaps into a machined groove around a shaft, built for higher axial load applications than a standard-gauge external circlip. Made from spring-tempered carbon steel to DIN 471.

Where this product is used

Heavy duty external circlips are used wherever a shaft-mounted component is subject to higher axial loads than a standard circlip is rated for — the ring seats into a machined groove around the shaft and holds the component captive against axial movement.

• Higher-load bearing, gear and pulley retention on shafts in industrial gearboxes and heavy machinery.
• Heavy vehicle, earthmoving and agricultural equipment drivetrain component retention.
• Applications where a standard-gauge circlip has previously failed or deformed under load.

Key specifications

Selecting the right option

Choose the heavy duty option where axial loads are higher than a standard external circlip is rated for, or where a standard-gauge circlip has previously deformed in service — otherwise our standard external circlip range covers general workshop and automotive use at lower cost. Match the circlip to the exact shaft diameter for your application and check it against the machined groove dimensions in your equipment drawings.
