Hydraulic Motor Selection Guide
Before purchasing a hydraulic motor, determine the following:
1. Required Torque
Determine the torque required to drive the equipment.
2. Operating Speed
Establish the required RPM, including minimum, normal and maximum operating speed.
3. Hydraulic Flow
Available hydraulic flow affects motor speed.
4. Hydraulic Pressure
Check both normal operating pressure and peak pressure.
5. Motor Displacement
Displacement is normally specified in cc/rev or similar units.
6. Mounting
Check the flange, bolt pattern, pilot diameter and mounting orientation.
7. Shaft
Confirm:
- Splined shaft
- Keyed shaft
- Tapered shaft
- SAE shaft
- DIN shaft
- Shaft diameter
- Shaft length
8. Hydraulic Ports
Check port size, type and position.
9. Duty Cycle
Tell us whether the motor operates:
- Continuously
- Intermittently
- Under shock loads
- At high starting torque
- At very low speed
- At high speed
10. Application
Always provide the machine and function for which the motor is being used.
Tips for Buying a Hydraulic Motor
Tip 1: Use the Complete Part Number
The complete part number is one of the most useful pieces of information when identifying a replacement.
Tip 2: Send a Photograph
A clear photograph of the hydraulic motor nameplate can significantly assist with identification.
Tip 3: Do Not Match Only by Appearance
Two hydraulic motors may look similar but have different displacement, pressure ratings, shaft dimensions or internal configurations.
Tip 4: Check the Hydraulic Circuit
The motor must be compatible with the pump, valves, hoses, controls and hydraulic circuit.
Tip 5: Check Case Drain Requirements
Some piston motors require specific case-drain arrangements and allowable case pressure.
Tip 6: Check Pressure and Flow
Do not select a motor solely based on physical size. Verify the hydraulic operating parameters.
Tip 7: Check the Application
A motor designed for a conveyor or sweeper may not be suitable for a heavy-duty mining drive.
Tip 8: Consider OEM and Aftermarket Options
Depending on availability and budget, Nkokhi Group can investigate OEM, aftermarket and equivalent replacement options.

Frequently Asked Questions
What is a hydraulic motor?
A hydraulic motor converts pressurised hydraulic fluid into rotary mechanical power. The motor uses hydraulic pressure and flow to generate shaft rotation and torque.
What are the main types of hydraulic motors?
The main types include gear motors, orbital/gerotor motors, vane motors, axial piston motors, bent-axis piston motors and radial piston motors.
What is an orbital hydraulic motor?
An orbital hydraulic motor is a low-speed, high-torque motor using an orbital/gerotor-type operating principle. It is commonly used in mobile equipment, conveyors, sweepers, augers and other applications.
What is a hydraulic piston motor?
A piston motor uses pistons to convert hydraulic pressure into rotary movement. Axial piston and radial piston motors are commonly used for demanding hydraulic applications.
What is the difference between an axial and radial piston motor?
Axial piston motors arrange pistons parallel to the motor’s axis of rotation, while radial piston motors arrange pistons around the central axis. Radial piston motors are particularly suited to high-torque, low-speed applications.
