1. Market Background

In European and North American markets, compact mini excavators are widely used for residential landscaping, garden renovation, farm maintenance, and small construction projects. These machines require swing-drive components that fit within limited installation spaces while meeting their operational load requirements.

For hydraulic swing motor selection, output torque and rotational speed are important, but mechanical compatibility also plays a critical role. Shaft-end gear specifications must match the machine's transmission design to ensure proper installation and integration.

2. Customer and Application Scenario

This export project targeted the European and North American markets, supplying 220 KSD Series Hydraulic Swing Motors for residential mini excavator swing-drive applications. Delivery was scheduled within 15 days.

For compact excavators, the connection between the swing motor and the transmission mechanism is an important selection consideration. Gear module, pressure angle, and tooth count must be checked against the equipment design before the final motor configuration can be confirmed.

3. Our Solution

For this project, we supplied the KSD Series Hydraulic Swing Motor with a focus on shaft-end gear configuration and application compatibility. The series offers gear modules of 4, 4.5, and 5, with a gear pressure angle of 20°. These options provide a basis for matching the motor to different transmission interface requirements.

According to the product catalogue, the KSD series is available in 160, 195, 245, and 305 cc displacement options, with a maximum speed of 80 RPM. The corresponding catalogue output torque ratings are 305, 388, 506, and 678 N·m.

Final model selection should consider the excavator's swing load, hydraulic system pressure and flow, gear tooth count, and mounting interface. Matching these parameters helps avoid selecting a motor based on displacement or torque alone.

The project was organized around an order quantity of 220 units, with delivery targeted within 15 days to support the customer's component procurement and assembly schedule.

4. Customer Feedback and Project Progress

The confirmed project information covers the KSD series, order quantity, application, and delivery requirement. Specific customer testimonials, installation test results, and long-term operating data have not been provided. Therefore, no unverified claims are made about actual field performance or customer satisfaction.

5. Summary: Key Parameters for Swing Motor Selection

This project highlights the importance of checking mechanical interfaces alongside hydraulic performance when selecting a swing motor for a compact mini excavator.

For the KSD series, key selection parameters include gear module, 20° pressure angle, gear tooth count, displacement, output torque, and hydraulic system pressure. Mounting dimensions and transmission compatibility should also be verified before ordering.

By confirming these requirements in advance, equipment manufacturers and purchasing teams can narrow down suitable swing motor configurations and reduce the risk of interface mismatch. For bulk purchasing enquiries, providing the excavator model, gear specifications, and hydraulic system data will help establish the appropriate KSD configuration.
