Ball Mill TRUNNION BEARINGS. Swivel type lead-bronzebushed trunnion bearingsare generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion.
