Tolerance Values Dimension Tables 10 29 29 30 Spherical Roller Bearings Design and configuration Attention 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 (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 * This only applies to spherical roller bearing Design and configurations Series Type EX EX1 E E2 239 230 36 20 E AEX 40 38 20 36 /1000 240 24 36 231 20 34 36 /800 241 22 32 36

lubrication holes and a groove for feeding lubricant The outer ring may also be configured with oil holes only depending on fitting, mounting or service conditions NACHI Spherical Roller Bearings are subjected to a heat-stabilization treatment as standard They can be used at operating temperature of up to 200˚C with minimal dimensional changes occurring Lubrication holes and groove Modification to

du D D du Misalignment Mounting bearings with tapered bore Maximum permissible misalignment angle is about 2˚ under general service conditions But its angle will vary with the series, service condition and surrounding structure As rotational speed increases, misaligned bearings will tend to generate more noise Due to noise constraints, the practical maximum misalignment in a bearing may be considerably less than the maximum permissible misalignment Mounting bearings with a tapered bore requires some experience and technique Bearings with tapered bore are always mounted with an interference fit on the shaft To measure the amount of interference fit on the shaft, the axial displacement of the inner ring or the reduction of radial internal clearance due to the interference fit can be used Generally, the measurement of reduction in radial internal clearance is a more reliable method than measurement of the axial displacement of the inner ring Unit: mm Nominal bore diameter d
