You receive one heavy duty one way freewheel sprag clutch ball bearing designed for small engines and lawn gear.

You press this compact unit straight onto shafts in skateboards, inline skates, and electric motors without hunting for extra bolts.

💡 Why pick a sealed overrunning sprag clutch bearing for light equipment?

The one way freewheel mechanism locks solid when you push forward and spins free when tension drops. This handy setup saves your drivetrain from reverse wear and keeps momentum rolling smoothly.

- Standard steel races handle heavy radial loads while keeping internal grit out. - Chrome rolling surfaces reduce drag and extend service life on low RPM gearboxes. - Direct press fit mounting trims down assembly time on custom DIY projects. ✝️
