[Al Skierkiewicz]

The bearings in the CIM motors are not designed for any force to be applied as a side load and there is no real thrust bearing to prevent the shaft of the motor from pushing into the motor. The CIM bearings are simple bronze bearings. It is best to have an external bearing point on the motor shaft for side loads. Without an external bearing point, the CIM bearing will exhibit significant wear and the gears will pull out of alignment.
