💡 How does a one way sprag clutch bearing work to make backstopping handy?

You mount these freewheel units to stop reverse rotation while letting the primary shaft spin normally.

- Tolerance machined rings engage fast to handle sudden torque changes

- Spring biased rollers cam outward quickly when load shifts directions

- Prepacked high heat grease protects the mechanism from early wear cycles
