Note: 1. The table data is applicable to 50Hz motor. For 60Hz motor, the time interval should be multiplied by 0.8;
2. For vertical motor installation, the lubrication interval shall be divided by 2;
3. Re-greasing intervals should be halved for every 15°C rise above 70°C. . Permissible forces at the shaft end
Maximum radial force (for pulley drive system): The maximum allowable radial force F0(unit: N) for radial load is based on the premise that the load line (center of pulley) must be within the length of the motor shaft extension (the motor shaft elongation is shown in the installation size code E size). The radial force length X (mm) is the distance from the axial extension shoulder to the radial force F0 action line, so when the length X= Max, it is the total length of the axial extension (size value E). Maximum allowable radial force as below table.


. Bearing life
For standard ball bearings, under the action of allowable load, the bearing design life of the motor can meet the following requirements: at least 20000 hours for the 2-pole motor, 4 poles, 6 pole motor at least 30000 hours (refers to the motor life under normal operation at 50Hz and normal maintenance as required).
