Cone Crusher Thrust Bearing

The cone crusher thrust bearing, a key component handling axial loads (up to thousands of kilonewtons) at the main shaft bottom or between the adjustment ring and frame, supports vertical forces, enables smooth rotation, maintains alignment, and integrates with lubrication systems. It operates at 500–1500 rpm, demanding high strength and precision.​ Composed of a 42CrMo thrust collar (HRC 50–55 surface), babbitt/bronze thrust pads, a cast iron/steel housing, lubrication elements, locating devices, and seals, it forms a robust assembly.​ Manufacturing involves forging and heat-treating the collar, casting/bonding babbitt to steel for pads, and sand-casting the housing, followed by precision machining. Assembly includes pad installation, lubrication integration, and alignment checks.​ Quality control covers material testing, dimensional inspection, NDT (UT, MPT), performance trials (load, friction), and lubrication validation. These ensure reliable operation in mining and aggregate processing.
