UBC bearings developed for various coal machineries, represent this industry’s leading anti-wear and endurance performance. The service life of UBC bearings in key parts can reach 15,000 hours, and the big load capacity can greatly reduce the damage rate of the bearings. Easy for installation and excellent impact load resistance are of two additional features of UBC bearings. Good lubrication and sealing performance, ensure smaller friction coefficient, doubled bearing service life.
