OCR SHAFT-MOUNTED GEAR REDUCERS SERIE RP 1C 160, whenever belt transmission between the engine and the gearbox is required, are implemented directly on the shaft of the machine to be controlled. 

The SERIES includes 3 different nominal reduction ratios: 6,27 – 9,82 – 12,8.

Gear reducers are grease-lubricated and supplied with grease and torque arm

AR Backstop Device is enforceable on these gears both with clockwise (ARO)  and anticlockwise (ARA) free rotations. This holdback’ equipment (ruota libera), which helps to prevent the driven equipment from running backwards, can be quickly implemented on the gear even without removing it from the controlled machine. It is mounted on the high-speed shaft from the opposite side to the shaft end. 

No maintenance is required during operation. 

To place an order for a non-commercial replacement, in addition to the position and its relative denomination, it is necessary to specify the gear transmission ratio indicated on the plate. 

Shaft-mounted gear reducers are mainly used for controlling conveyor belts, bucket elevators, augers, mixers and crushers.
