The qualitative requirements for ball, cylinder and taper roller bearings have increased significantly. Priority criteria include the obligation to save energy, the extension of guarantee periods, increased load-bearing and the trend towards smaller dimensions and simultaneously increased service life.
Thielenhaus machines have been used in the Microfinish / Superfinish of roller bearing raceways and rolling elements for decades. Thanks to Microfinish / Superfinish machining, the roundness and roughness of the relevant anti-friction bearing surfaces are significantly improved, thus delivering the highest levels of quality. After machining, the anti-friction bearings also display a higher load-bearing capacity and longer service life, as well as lower noise emissions.
