"These trunnion bearings are selected based on the grinding mill size and type, in addition to the site conditions and output required of the mill," says Fabio Rebecchi, Product Manager for NTN–CBC Australia. "In these instances, we're seeing a trend for extra-large spherical roller bearings, which are critical in ball mill application.

The effectiveness of normal lubrication protection is reduced when the mill is shut down for any length of time, and many mills are fitted with manually operated hydraulic starting lubricators, which force oil between the trunnion and trunnion bearing, preventing friction damage to the beating surface, on starting, by re-establishing the ...

The mill trunnion bearings are a key assembly in mill operation. If the trunnion bearings are not reliable the complete mill is not reliable. Various trunnion bearings designs are used, ranging from fully hydrodynamic to fully hydrostatic. The design charge load defined earlier is a direct input in the calculation of the trunnion bearing pressure.
