Swing Motor FAQ:


1. What is the Swing Motor ?

The swing motor, also named slew motor, is an integrated hydraulic rotary drive unit. It consists of piston motor, planetary reducer and built-in parking brake. It converts hydraulic energy into high torque power. It enables the upper body of excavators to rotate continuously by 360 degrees. Integrated valves protect the unit against shock and overload. It is the core component for rotary movement of construction machinery.

2. What makes the Swing Motor ?

It consists of a hydraulic piston motor, planetary reduction gearbox and built-in parking brake. Integrated multi-function valves are assembled inside the housing. Precision friction pairs and reliable sealing components are adopted. High-strength cast housing ensures stable operation under heavy loads. All components are closely matched into one compact assembly.


3. What is the working pressure range of Swing Motor ?

The rated working pressure ranges from 21 MPa to 28 MPa. The maximum instantaneous pressure can reach 28 MPa to 32 MPa. Please select the suitable model according to your machine configuration.


4. Can Swing Motor replace other brands?

Our swing motor can serve as a replacement for many mainstream brand models. It requires consistent displacement, installation dimensions and pressure parameters. Please provide the original part number or machine model for compatibility confirmation. Direct interchange is available after verifying all technical data. We support aftermarket replacement for various excavator swing drives.

5. What is the typical speed range of Swing Motor ?

The typical operating speed ranges from 0 to 120 rpm. The actual output speed depends on hydraulic flow and machine tonnage. Low-speed and high-torque performance ensures stable slewing operation.


6. Do you provide OEM or customized services?

Yes, we support OEM and customized services for swing motors. We can adjust displacement, installation size and internal parameters as required. Custom logo, packaging and technical specifications are available. Please send your detailed requirements for further quotation.

7. How can I get a quotation quickly
