Borelli Group 3 SAE A Speed Reducer – 96000 Series
The Borelli Group 3 SAE A Speed Reducer – 96000 Series connects hydraulic motors used in agricultural machinery, earthmoving equipment and marine applications. Manufactured from aluminium and cast iron for maximum mechanical strength, it features UNI 18NiCrMo5 steel gears. It supports input speeds of up to 3000 rpm while providing a stable output speed of 200 rpm. SAE 90 oil lubrication ensures reliable continuous operation at temperatures of up to 120°C.
The available product codes are: 96001, 96002, 96004, 96005.
The 96000 Series speed reducers are designed to manage and optimize the connection of hydraulic motors used in self-propelled agricultural machinery, earthmoving equipment and demanding marine applications. The mechanical system adjusts the operating speed of hydraulic motors according to specific application requirements: the output speed of the speed reducer is 200 rpm, while the motor input speed must never exceed the maximum limit of 3000 rpm. This mechanical coupling ensures smooth and efficient power transmission, maintaining operational stability even in demanding working environments.
The Borelli Group 3 SAE A Speed Reducer – 96000 Series is designed to withstand high mechanical stresses and continuous operating cycles. The external housings are manufactured from high-strength aluminium and cast iron. The internal transmission gears are carefully designed and dimensioned in full compliance with international ISO/DIN 3990-80 standards, using special UNI 18NiCrMo5 steel. The gear teeth undergo precise profile correction and shaving processes to reduce friction and wear over time. The transmission shafts, manufactured from 16CrNi4 steel, are connected to the gears using robust mechanical keys.
The nominal torque ratings specified in the technical tables are calculated for continuous-duty operation. The speed reducer is designed to safely withstand operational overloads: under intermittent-duty conditions, torque values may exceed their nominal ratings by up to 20%. The reducer’s flange mounting system provides flexibility for the end user. Hydraulic motors with cylindrical shafts can be mounted directly using a keyed connection, while splined shafts compliant with DIN or SAE standards can be connected through direct coupling. The assembly supports a rated power of 20 kW.
The manufacturer requires the exclusive use of SAE 90 lubricating oil to maximize the service life of the reduction gearbox. The housing has a maximum oil capacity of 0.350 litres. The operator must visually inspect the oil level through the dedicated sight glass every 2000 operating hours. The maintenance schedule requires the first oil change to be performed after the initial 100-150 hours of operation. Proper lubrication and maintenance help dissipate generated heat and keep the continuous operating temperature within the maximum limit of 120°C.
