The Anca RGX spindle is a grease lubricated and stator driven spindle capable of running up to 8,000 rpm.
CHALLENGE
When this Anca RGX spindle arrived at our facility we noted that the bearings were very loud when rotated by hand in assembly. The power cord jacket was also significantly worn incoming. All spindle electrical functions however tested good. Upon disassembly, we noted that the spindle interior was contaminated with oil. The grease in all bearings was degraded by said oil contamination. Inspection of the critical dimensions showed us that the wheel hub OD taper had >50µ runout. Runout measured on the bare shaft was >40µ.
SOLUTION
The following actions were performed on this Anca RGX spindle:
- Clean, inspect overall dimensions
- Repair external power cord and seal entry into housing
- Grind, chrome plate, and finish grind the wheel hub taper OD
- Replace bearings, o-rings, and assembly screws
RESULT
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
