The new design has proven to improve trunnion liner reliability, durability, and maintainability of the mill trunnion linings and bearings. The main lining acts as a sleeve insert that is secured in the trunnion by a retaining ring. Dividing the trunnion liner into two pieces enables better distribution of the loading conditions.

A trunnion mill has the trunnion bearing supporting the entire weight of the mill. Changing out a trunnion rolling element (or sleeve) bearings requires the support an entire end of the mill. Specialize cradles and lifting gear is required. With a slipper pad bearing mill, the load is distributed via 4 (or more) pads per end.

The ratio of the trunnion thickness to trunnion diameter in a mill of 2,134 m diameter is almost twice that of a mill of 5,8 m diameter, a ratio (T/D) of 0,116 to 0,069 for the large mill. However the design stress levels at the trunnion/head transition in the case of the large mill are almost 250% of those in the small mill.
