Mining Spiral Rubber Disc Q235 Return Roller Conveyor

Mining Spiral Rubber Return Rubber Disc For Conveyor Roller

Main Features of SPD Return Rubber Disc Roller

1.The bearing housing and steel tube are assembled and welded with a concentric automatic, welding machine.

2.Cuting of the steel tube and bearing is performed with the use of a digital aute device/machine/equipment.

3.Fabrication of the roller is effected by an auto device and 100% tested for its concentricity.

4.Roller and supporting components/materials are manufactured to ISO/BS/JIS/DIN//CEMA standard.
