Custom Turning and Grinding of Steel Tapered Roller Bearings
In need of a large tapered roller bearing, a client in the bearing repair business came to Hollander Machine to benefit from our manufacturing skill and expertise in custom turning and grinding. Made from 100% U.S. E52100 steel, the bearing was rough turned to the specified diameter and finished to its final outside diameter on our Unison DedTru surface grinder. Weighing 26 lb, the bearing measured .125″ to 5.00″ for outside diameter and was 4.00″ long. Working with turning and grinding tolerances of ±.0002″, we performed in-process inspections make sure that the bearing met Precision’s high-quality standards.
