United Mechanical Bearing Co., Ltd.

UND bearings are widely used for the Mining Industry. Our bearings are found in mining equipment worldwide and produced with precision for our valued customers. 

From low-slung underground miners that “mill” the coal from the “wall to behemoth drag lines that remove the overburden, UND bearings has been supplying heavy duty cylindrical and tapered roller bearings for that industry for decades.  Many bearings are used in gear reducers, both parallel shaft and planetary designs that reduce input motor speed while increasing torque.
