BearingStar
Superfinishing of ball and roller bearing raceways with the Thielenhaus BearingStar
ultra-flexible platformToday, the precision machining of rolling bearings must be carried out economically and flexibly to the highest quality standards. The BearingStar is a modern, modular machine solution that has been designed precisely for these objectives.
Microfinish/superfinish machining significantly improves the roundness and roughness of the relevant rolling bearing surfaces and achieves the highest quality. After machining, the bearings also have a higher load capacity and longer service life as well as lower running noise.
