BMC has just installed a new machine that can grind rings up to 140 inch diameter rings. We are able to grind cylindrical, ball, spherical, and tapered roller raceways. Slewing Ring Bearings / Turntable Bearings: We can regrind ball and roller raceways with or without external or internal gear teeth. By December of 2010 we will have another machine running that will grind up to 180 inch (15 feet, 4.5 meters) diameter rings; and by July of 2011 we will have a machine installed that will be able to grind raceways up to 264 inches (22 feet, 6.7 meters) in diameter.
We can quote machine time on all 3 machines today so that you can better forecast your projects. Our web site will keep you up to date on the machine installation dates.
Thank-you for your interest in BMC; please call us to see how we can help you!
