A Mazak QT20 lathe runs 120mm ID bearings on the spindle and has a spindle bore of ″. That works out to a wall thickness of about ″ or about 29mm. Now let's say we want to build a lathe spindle with a spindle bore of 2″. Let's give it a 1″ wall thickness, so we need bearings with 4″ ID which is 101mm.

3. Mill head 4. Trunnion liner 5. Bearing liner The best a ball mill can get FL has installed almost 4000 ball mills at locations worldwide which has given us a unique insight into the stresses and strains arising out of ball mill operations. The large alternating stresses placed on ball mill trunnions and heads are a great example.
