Feature of motorized electric drum pulley

1.Steady running, reliable quality and reduce maintenance;

2.Less movement longitudinally, rotating smoothly, extends the life span;

3.Various bearing housing and sealing structure are available for the customers choice;

4. Multipass labyrinthine sealing,preventing the mixed dirt and water immersed; 

5.Manufacturing by steel pipe specially for of high precision roller, ensuring the strong load, 

   low shaking and less noise.
