Borelli Group 2 SAE A Speed Reducer – 95000 Series
The Borelli Group 2 SAE A Speed Reducer – 95000 Series is designed for connecting hydraulic motors used in self-propelled agricultural machinery, earthmoving equipment and marine applications. Manufactured with a high-strength aluminium and cast iron housing, it features UNI 18NiCrMo5 steel gears compliant with ISO/DIN 3990-80 standards and 16CrNi4 steel shafts. It supports a maximum input speed of 3000 rpm.
The available product codes are: 95001, 95002, 95003, 95004.
The Borelli Group 2 SAE A Speed Reducer – 95000 Series is a precision mechanical solution designed for integration into complex hydraulic systems. Its primary function is to provide an efficient connection for hydraulic motors used in self-propelled agricultural machinery, earthmoving equipment and specific marine applications. The system is designed to reduce rotational speed: the speed reducer has a specified output speed of 200 rpm, requiring the hydraulic motor speed to be adjusted accordingly, with the strict requirement that the input speed must never exceed 3000 rpm. The hydraulic motor can be connected using a cylindrical keyed shaft or a splined shaft compliant with DIN or SAE standards for direct coupling.
The external structure of the 95000 Series speed reducers consists of aluminium housings combined with cast iron components, ensuring high mechanical strength and long-term operational durability. The internal transmission system incorporates gears designed in strict compliance with international ISO/DIN 3990-80 standards. These gears are manufactured from UNI 18NiCrMo5 steel and feature corrected and shaved gear teeth to maximize smooth meshing. Power transmission is handled by shafts manufactured from 16CrNi4 steel, which are securely connected to the gears using keys. All models in the series have a constant weight of 5 kg and support a power rating of 10 kW.
The torque specifications (M1 and M2) defined for the Borelli Group 2 SAE A Speed Reducer – 95000 Series are calculated for continuous-duty operation. When the component operates under intermittent-duty conditions, the nominal torque ratings may be exceeded by up to 20%. Regarding thermal performance, the speed reducer is designed to operate reliably provided that the temperature during continuous operation does not exceed the maximum limit of 120°C.
To preserve gear integrity and ensure proper operation, the manufacturer recommends the correct use of SAE 90 lubricating oil. The lubricant level, with a maximum oil capacity of 0.220 litres, must be visually inspected through the dedicated sight glass every 2000 operating hours. The first oil change must be performed after an initial running-in period of 100 to 150 operating hours.
