the vast majority of medium and large companies are now series bearing products do not need a full inspection

Bearing outer ring after quenching, tempering and other heat treatment after , can improve product strength, hardness , wear resistance , fatigue strength and toughness . Previously, the use of process equipment bearing mesh belt furnace and quenching furnace rollers , Slim-bearing tempering, there has been distortion problems affecting the efficiency quality. Especially greater than 150 mm in outer diameter of the large product , the deformation is more pronounced. In recent years, bearing the company's market has been expanding from the traditional automotive industry market more towards wind power bearings, machine tool bearings and other emerging industries range , product specifications growing, medium and large Slewing Bearing  outer ring more and more . How to solve the problem of a product deformation caused by the traditional process , the company has become an urgent need to address the "big obstacle ."
Since the deformation meet the requirements, the vast majority of medium and large companies are now bearing products do not need a full inspection , plus reducing stress to both shaping and processes , in the middle class remains unchanged, the product flow rate, greatly improving the production efficiency. Furthermore , the bearing outer taper becomes smaller, the subsequent grinding allowance is reduced accordingly. In terms of cost savings , shaping, five employees to streamline the inspection process , the annual wage bill savings of at least 200,000 yuan ; same time, to reduce stress and subsequent shaping of the original 40,000 yuan per year of electricity use , the benefits of these savings are very impressive .
