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.
