External Snap Ring, 2-1/2"

External Snap Ring, 2-1/2"

The SRE212 External Snap Ring is a durable retaining ring designed to hold components securely on a shaft while preventing unwanted axial movement in mechanical assemblies. Sized for a 2-1/2" shaft, this external snap ring installs into a machined groove on the outside of the shaft to keep bearings, gears, pulleys, and other parts firmly in position. Manufactured from spring steel for strength and flexibility, it maintains constant tension in the groove while still allowing components to be removed for service—because sometimes the smallest piece of hardware is the one keeping the entire assembly where it belongs.
