Okuma Cadet V4020 Spindle Repair

Okuma Cadet V4020 Spindle Repair



CHALLENGE

Upon initial inspection, this Okuma Cadet V4020 spindle's bearings were very noisy when rotated by hand. After disassembly, our technician discovered that the front and rear lnpro seal bearing isolators had failed, and the rear bearing pair was heavily contaminated. Grease had almost completely washed out of the front bearing tri-set. The tooling taper ID measured with high runout. We also found that the gripper fingers exhibited severe wear on retention surfaces.  

SOLUTION

All original parts were thoroughly cleaned before reassembly of the repaired Okuma Cadet V4020 spindle. This straightforward repair required replacement of all bearings, Belleville washers, grippers, Inpro seals, o-rings & assembly screws. We performed a kiss grind to the tooling taper ID to address runout. Every Northland spindle repair undergoes testing and break-in, and  must pass a rigorous quality assurance process before being shipped back to the customer with a 1-year warranty.
