# Calculation Of Slide Shoe Bearing

• ### Trunnion Bearing Slide Shoe Bearing Grinding

Traditionally trunnion bearings have a much higher specific load, as the available surface area is restricted by the trunnion diameter. Slide shoe or slipper pad bearings (as fitted to shell supported mills rather than trunnion mounted mills) are fully self-aligning, subjected only to compressive loads, and as long as the oil supplied to them is maintained, they will outlast

PV is determined by multiplying the specific bearing load or pressure (p) by the sliding speed (v). Bearing materials are rated by a PV limit, with the PV limit representing the highest combination of load and speed under which the bearing material will operate. The PV

• ### Understanding Journal Bearings EDGE

Bearings are used to prevent friction between parts during relative movement. In machinery they fall into two primary categories anti-friction or rolling element bearings and hydrodynamic journal bearings. The primary function of a bearing is to carry load between a rotor and the case with as little wear as possible.

• ### Hydrostatic and Hydrodynamic Bearings Selection

The pivoted shoe concept was applied to journal bearings and extensive tests have proved this is the most effective design. The pivot allows the shoe to rotate and form a wedge. The pivot surface is spherical to allow 360 rolling freedom. Hydrodynamic pivoted shoe bearings provide considerable benefits.
