Design and configuration 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 the table below for the roller, guide ring and cage design for NACHI Spherical Roller Bearings. They can sustain radial and axial loads. Attention (1) For high axial load applicadtions, the axial load Fa must not exceed 0.6 of the radial load Fr. If the axial load exceeds 0.6 Fr, please contact NACHI engineers for design assistance. (2) For applications where oscillating loads (such as shaker screen applications) or high speed is involved, please contact NACHI for design assistance. (3) In very lightly loaded or no load conditions, sliding motion can occur which could damage the bearing. To prevent this damage, bearings must be subjected to a load greater than 0.02 Cr (basic dynamic load rating). (4) The material coefficient number of the bearing is taken into consideration for the dynamic load rating.
