Bearings and Spare Parts
Where alternative parts are offered, we make no claims as to their suitability. Selection of the most suitable bearings and parts is the responsibility of the customer. We recommend you replace bearings with the same type if that type is working well. High speed caged bearings are better suited to handle vibration than standard caged bearings.
Suitable for locking sprockets, pulleys, eccentric shafts.
Locks components with a bore of (D) to shafts with a diameter of (d). C60 Steel (060A62). Outer ring expands whilst inner ring contracts. Flange eliminates axial movement of secured component. During tightening of the screws, the hub must be able to perform axial movement. Clearance h8 / H8. Surface roughness Rt max 10um shaft / hub.
