Spherical roller bearings with rocker technology mean fewer spare parts. Automated lubrication. The automated lubrication systems are either a cabinet or drum type depending on the mill size and the application in systems provide lubrication to the main bearings and seals, pinion bearings and seals, and pinion gear. Drive

Now, when the cement grinding ball mill is started, vibration values are around 14 mm/s, first 4 harmonics of the GM, and then for about half an hour they go up to 28 mm/s in horizontal direction while in the vertical and axial direction there is no such change.

vibration. A small relative motion between balls and raceway occurs in nonrotating ball bearings that are subject to external vibration. When the bearing isn't turning, an oil film cannot be formed to prevent ~rina~ ~mks raceway wear. Wear debris oxidizes and accelerates the wear process. Correct by isolating bearings from external vibration, and
