OCR was founded in the 1960’s, by the beginning of the 1970’s OCR decided to redirect and verticalize its abilities, shifting its production towards shaft-mounted OCR gear reducers. In 1987 Andrea Alessandrini took over the reins of the family business ambitiously decided to drive the company in to the foreign market for the very first time. This new challenge eventually drove the decision of abandoning the production of worm gear reducers, to specialise in shaft-mounted gearboxes, able to meet the various application needs of different sectors.
Over the years the SERIES’s has been expanded to keep up with technological developments and better meet company and customer requirements. Today OCR have over 50 years of experience in the sector and a well known presence in both domestic and foreign markets.
OCR Shaft-Mounted Gear Reducers
OCR specialise in the production of shaft-mounted gear reducers, both single and double reduction. The speed reduction takes place employing spur gears, allowing to reach greater performance and efficiency whilst improving reduction ratios in comparison to other types of speed reducers.

RP 2C Series
The RP 2C Series of shaft-mounted OCR gear reducers are the most commonly used gearboxes enabling two different reduction stages. This is made possible by utilising spur gears allowing improvements in the machines performance and efficiency as well as reduction ratios.
- Sizes: 85, 105, 125, 150, 165, 180, 210, 250
- Nominal Reduction Ratios: 4 – 10 – 16 – 20 – 25
- Rated Power: From 0,6 kW up to 155 kW
- Nominal Torque: From 160 Nm up to 11280 Nm
RP 1C 122 Series
The RP 1C 122 Series shaft-mounted OCR gear reducers are designed for applications where power is transmitted via a belt between the motor and gearbox, they are installed directly on to the shaft of the driven machine. The RP 1C 122 are grease-lubricated and supplied with grease, but without torque arm (tensioner). No maintenance required during operation.
Nominal Reduction Ratios: 6,5 – 9,27 – 12, 4
Key Benefits
- Very High Efficiency
- Low Noise Levels
- Easily Assembled
- Easy Maintenance with minimal requirements.
- Wide Speed Range Available
