A steel plant project: product model, HM265849/HM256810 original rolling 120 square steel, vertical rolling mill, the steel mill changed to rolling 140-160 square steel! What we need to solve is: TIMKEN life is 7 days, NSK life is 30 days, as long as our life can reach 30 days! Our pre-sales engineer arrived at the scene: the shaft and bearing clearance fit, the shell and the bearing are also clearance fit, glycerin lubrication, speed 100-200 rpm! Cause analysis: TIMKEN 1. The material selection is wrong. 2. The clearance is not correct. NSK 1. The raceway profile of the low speed and heavy load is incorrect. 2. The gap is wrong! Improvement measures: Select suitable carburizing steel, combined with domestic materials and heat treatment level, change the pillar cage to window cage, redesign the roller and raceway contours, simulate the installation site, and re-match the clearance! The actual situation: the life can reach more than 3 months!
