GM2/ GM3A R24

Product catalog summary

Technical Specifications:

Equivalent Displacement: Calculated as motor displacement multiplied by gearbox reduction ratio (6.231:1).
Bore and Stroke: Varies by model, with bore ranging from 52mm to 63mm and stroke consistently at 40mm for GM2 R24, and 56mm for GM3A R24.
Specific Torque: Ranges from 42.13 Nm/bar to 78.51 Nm/bar depending on the model.
Pressure Ratings: Continuous pressure ranges from 110 bar to 210 bar, while peak pressure ranges from 230 bar to 350 bar.
Power and Speed: Peak power is consistent at 59 kW for GM2 R24 and 80 kW for GM3A R24. Minimum speed is 1 rpm, with maximum speed varying between 80 rpm and 120 rpm.
Weight and Oil Capacity: Approximate weight is 190 kg for GM2 R24 and 230 kg for GM3A R24. Oil capacity is 2 liters for GM2 R24 and 4.5 liters for GM3A R24.
Temperature Range: Operates between -20°C and +80°C.
Bolt Torque Setting: 561 Nm for coarse threads and 586 Nm for fine threads, with suggested bolt type M20 12.9.

Procedures and Recommendations:

For higher speeds, contact the SAI Technical Department.
The motor, brake, and gearbox share lubrication oil, but a separate oil brake unit is available on request.
Brakes should be periodically engaged and disengaged to maintain performance.

Order Codes:

Order codes include displacement, distributor type, distributor option, and other options such as internal seals and oil type.
Example codes are provided for both GM2 R24 and GM3A R24 models.

(3) Il motore, il freno ed il riduttore condividono lo stesso olio di lubrificazione. Unità freno fornibile su richiesta ad olio separato. (4) If the brake is engaged for a long time, the braking torque could increase considerably. The brake requires to be periodically engaged and disengaged to maintain the desired performances. (4) Quando il freno rimane ingaggiato per un lungo periodo di tempo la coppia frenante può aumentare considerevomente. Si consiglia periodicamente di pilotare il freno in modo da garantire i dati dichiarati. (5) Where n= gearbox output speed [rpm] and h= working time [hours] (5) Dove n= velocità in uscita del riduttore [rpm] ed h= durata di funzionamento [ore]
