The bearing is basically a sleeve mounted on the shaft and fit into the bore. Plain bearings are inexpensive, compact and lightweight. They have high load carrying capacity. Plain bearings are used for rotational, sliding, reciprocating or oscillatory motion. The bearing remains fixed while the journal slides on the bearing's inner surface.

A guideline for vibration limits at the top of the motor has been added as to ANSI/HI 9.6.4-2016 under Appendix C. The recommended limit (not intended to be used as an acceptance criteria) is 1.5 time the limit at the top of the discharge head. Location for testing: The measurement should be taken near the upper motor bearing. Reference figure C.1.

2.10.2 Vertical Mills. For more than 50 years vertical mills have been the mill of choice for grinding raw materials into raw meal. More recently they have become widely used for cement production. They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body.
