Spherical Roller Bearings

STB  Spherical Roller Bearings

withstand the most demanding conditions by resisting seizure and wear in spite of constant vibration, misalignment and shock loads. They maintain dimensional stability and can support high radial loads and moderate axial loads. Their performance enhancements include extremely tight radial clearance tolerance, extra precision on the bore and outside diameter & super-finished, heat-treated rollers with superior shock load capacity.
