Pipe materials: seamless steel pipe
Shaft materials:45#round steel and sleeve
Excellent Technology:
The pipe is cutted by using the flame cutting machine, and weld the inner pulley dise by using the professional pulley welding machine,alao weld the pulley sleeve & disc by using the positioner. We use the largedrum lathe process the outside circle.so that it ensures the pulley has theuniform thickness and small pulsation.
We process the whole shaft so that it ensures shaft concentricity and reduction for the eccentric shaft force. lt make sure the pulley move more stable.high-quality bearing which is hot charging and bearing block are equipped inner bearing Enlargement device, so the bearing can be easily pushed to the bearing position and it avoids the bearing damage fromthe beating.
