For shipping to Alaska or Hawaii please contact us. Shipping to Canada is available upon request.
Spherical Roller Bearings are particularly suitable for applications where misalignment can arise from error in mounting or from shaft deflection. NACHI Spherical Roller Bearings are manufactured in a number of design and material configurations depending on the type of application and size of the bearing. See Table 1 for the roller, the guide ring and cage design for NACHI Spherical Roller Bearings. They can sustain radial and axial loads.
