Orbital Hydraulic Motor

Orbital Hydraulic Motor – High Torque, Low Speed Motor for Mobile and Industrial Hydraulics

An Orbital Hydraulic Motor is a low-speed, high-torque (LSHT) motor used in a wide range of hydraulic drive applications. These motors are compact, efficient, and capable of delivering consistent torque under varying load conditions. Manufactured by leading brands such as Danfoss, Eaton, and Parker, orbital motors are essential in agriculture, construction, material handling, and forestry equipment.

Key Features of Orbital Hydraulic Motors:

1. Low-Speed, High-Torque (LSHT) Performance
   Delivers high torque at low speeds, making it ideal for applications where power and control are critical.

2. Orbital (Gerotor or Geroler) Design
   Features an internal gear set with an orbiting rotor, which enables smooth and consistent power delivery.

3. Compact and Lightweight
   Designed for tight installation spaces without compromising power output.

4. Wide Displacement Range
   Available in multiple displacements, typically ranging from 50 cc to 800 cc/rev, to suit a variety of torque and speed requirements.

5. Versatile Mounting Options
   Compatible with SAE, ISO, and DIN mounting flanges, with various shaft configurations like keyed, splined, and tapered shafts.

6. Bi-directional Rotation
   Capable of operating in both forward and reverse directions, offering greater system flexibility.

7. High Efficiency and Smooth Operation
   Designed for low internal leakage and efficient torque transfer, even under low speed or high load conditions.

8. Durable Construction
   Engineered with hardened components for high wear resistance, ensuring long service life even in harsh environments.

9. High Radial and Axial Load Capacity
   Integrated bearings support high side loads, allowing for direct mounting of wheels, pulleys, or sprockets.

10. Wide Range of Applications
    Suitable for wheel drives, augers, feed rolls, winches, conveyor systems, and other hydraulic machinery.

Common Applications for Orbital Motors:

• Skid steer attachments

• Agricultural sprayers and harvesters

• Forestry winches and saw heads

• Construction equipment (mixers, augers, drive systems)

• Industrial conveyor drives

• Marine and offshore equipment
