Product catalog summary

Specifications Overview:
The WS series hydraulic motors are designed to meet SAE and European standards with nine shaft and seven mounting options. They feature heavy-duty tapered roller bearings for increased side load capacity and a robust drive link for enhanced resistance to pressure and torque spikes. The motors include a three-zone commutator valve for high flow capacity and a standard case drain with an integral internal drain for extended shaft seal life.

Key Features:
The WS series is ideal for high torque applications under demanding conditions, such as agricultural equipment and skid steer attachments. They offer flow rates up to 76 LPM (20 GPM), torque up to 824 Nm (7,295 lb-in), and pressures up to 207 bar (3000 PSI) at continuous ratings, with displacements ranging from 80cc (4.8in³) to 496cc (30.3in³).

Performance Ratings:
Detailed performance ratings are provided for various models, including maximum speed, flow, torque, and pressure. Intermittent ratings apply for 10% of operation and peak ratings for 1% of operation.

Performance Data:
The document includes performance data tables and graphs showing the relationship between torque, speed, flow, and pressure for different displacement models, aiding in motor selection for specific applications.

Efficiency and Testing:
Efficiency is categorized into three ranges: 70-100%, 40-69%, and 0-39%. Displacement is tested at 54°C (129°F) with an oil viscosity of 46cSt (213 SUS).
