NU 313 EC
SKF
Radial Bearing Type
Single Row
Round Bore Type
65 mm Inside Diameter
140 mm Outside Diameter
The EC design contains improvements in guiding surfaces of flanges and roller ends, which means that EC bearings have a high axial load-carrying capacity.
Traction motors
Electric motors
Gearboxes
Improved roller-end-to-flange contact
Increased capacity
In accordance with ISO 15-1981
