KM1 Series Hydraulic Motor for Hydraulic Wrist Applications: A 380-Unit European and North American Order

1. Market Background

In European and North American machinery markets, compact equipment design places increasing emphasis on drive-unit dimensions, output requirements, and interface compatibility. A hydraulic wrist mechanism requires a suitable drive solution to support its intended rotational or motion-control functions. Selecting a hydraulic motor that fits the available installation space and matches the required operating parameters is therefore an important part of equipment design and procurement.

2. Customer and Application

The customer was based in Europe and North America and selected Keystone Hydraulic's KM1 Series orbital hydraulic motor for a hydraulic wrist application. The installation required consideration of the available space, motor housing, output shaft, mounting flange, and hydraulic port arrangement.

The order consisted of 380 units, with a delivery period of 15 days. In addition to product compatibility, a defined delivery schedule was an important part of the customer's procurement planning.

3. Keystone Hydraulic's Solution

Keystone Hydraulic supplied the KM1 Series orbital hydraulic motor as a candidate drive solution for the hydraulic wrist application. Its compact distribution structure and multiple displacement and connection configurations allow engineers to evaluate different options according to installation constraints and hydraulic system requirements.

The KM1 Series offers displacements from 50 to 400 ml/r, continuous torque from 81 to 435 N·m, and continuous speeds from 149 to 879 RPM. Actual performance depends on the selected model and operating conditions. Before final selection, engineers should verify the required torque, target speed, system pressure, flow rate, output shaft configuration, and mounting interfaces.

The 380-unit order was scheduled for delivery within 15 days, providing a defined supply timeframe for the customer's procurement and production planning.

4. Customer Feedback

The available project information confirms the application, order quantity, and delivery timeframe. However, no original customer testimonial or documented operating results were provided, so specific claims about customer satisfaction or performance improvements cannot be verified.

For this type of application, subsequent evaluation can focus on installation compatibility, movement under actual loads, and operating performance over time. These observations can help guide future motor selection and application adjustments.

5. Case Summary

This project illustrates the use of Keystone Hydraulic's KM1 Series orbital hydraulic motor in a hydraulic wrist application for the European and North American market. When installation space is limited, compact construction, displacement options, and connection flexibility are important selection considerations.

Matching the motor to the required torque, speed, pressure, flow rate, and mechanical interfaces helps engineers assess application suitability. Equipment manufacturers seeking a hydraulic wrist drive solution are encouraged to provide application details and mounting drawings when requesting a quotation.
