Rotary kilns, dryers and mills run on trunnion bearings and support rollers that must survive high loads, misalignment and elevated temperature. We manufacture ZA303 and copper-based trunnion bearing shells, support-roller bearing pads and hollow-shaft bushings engineered for these conditions, cast and machined to the original drawing or measured on site.
