Installation and Usage
ASNU (NFS) clutch is out wheeled roller one-way clutch (ramp & roller), internal free bearings.
Installation requires bearing fit to withstand axial and radial forces.
1, ASNU clutch nominal diameter and 63 deep groove ball bearing consistent.
2, ASNU clutch outer ring n6 tolerance level, easy to push the bearing bore tolerance H7 level.
3, the clutch outer side, with additional grooves, so it could be more efficiently transmitted torque.
4, such as bearing hole tolerance level is K6, no need to use the groove, but make sure that the
bearing hole has a sufficient strength is not expanded after installation.
5, about the lubricant:
When in use ASNU clutch lubrication and sealing.
ASNU clutch shipment has been oiled, but must be added before use enough oil.
