Select DGBB for shaft diameter of 60mm which rotates at 1440 rpm with radial load of 2500N &axial load of 1200N, expected life of the bearing is 25000Hrs and Service Factor is 1.2.
Given Data
SKF Bearing Type- Deep Groove Ball Bearing
Shaft Diameter (D)=60mm
Rotation (N) = 1440 rpm
Axial Load- 1.2kN
Radial Load-2.5kN
Expected Life $L_h=25000$ Hrs,90% pos
Service Factor (S)=1.2
Bearing Temp- 135℃ Assumed
