The difference between these two is the location in the motor. The drive shaft bearing is located close to where the drive shaft extends out of the motor. The opposite drive shaft bearing is on the opposite side of the drive shaft. Every manufacturer has their own way of displaying bearing information and this can vary widely between manufacturers.

Grinding represents a crucial process step in ore processing – for the overall perfor-mance of a mine. That's why the gearless drive of a grinding mill is the crucial piece of equipment in the concentrator – and why it is subject to very high demands. High availability and reliability through-out the entire lifecycle are a must, while
