? Each roller frame arm shaft bore machining is the boring one clamping roller frame molding type, high concentricity, wheel rotation flexibility. ?. Active wheel frame and driven roller frame roller frame drum core are price, after heat treatment molding process. ?. Wheel all-plastic combinations, outsourcing, Steel Roller heat-resistant rubber, bearing capacity, long cycle rubber layer, no distortion, no unglued. Self-adjusting wheel frame: roller bracket: high quality sheet metal cutting Welded annealing after finishing from the small roller frame structure of the roller bearing from the connecting role, curved wheel on board every standard configuration with the rotary shaft connection angle is 90 degrees (according to user requirements can be 110 degrees) rotation speed reduction mechanism: Active frame separately by two motors through cycloid were two wheel drive two rollers on the stand, then straight from Grade gear wheel drive and four wheel frame synchronous operation, the driven wheel frame without drive, driven by the capstan roller rotates the workpiece moving follower. Wheel frame type, Wuhan three Rainbow Heavy Industries (certified), roller frame provided by Rainbow Heavy Industries Co., Ltd., Wuhan three. Wuhan three Rainbow Heavy Industries Ltd.
