Product catalog summary

Overview: The document outlines the specifications and performance data for the White Drive Products WG series hydraulic motors, designed for light-duty applications. These motors are recognized for their durability and efficiency, featuring the Roller Stator® design that minimizes friction and extends motor life. They are ideal for applications where sideload is a concern, offering displacements from 41 to 404 cm³ per revolution.

Specifications: The WG series motors come with various mounting, shaft, and port options. They are engineered to deliver high performance at a cost-effective price, with specific maximum speed, flow, torque, and pressure ratings for different models. The motors include a high-pressure Buna® shaft seal and a heavy-duty drive link for enhanced durability.

Features and Benefits: Notable features include the Needle Roller Bearing for optimal load placement, a high-pressure shaft seal for superior performance, and a Roller Stator® design for increased efficiency. Additionally, the motors have a rubber-energized steel face seal that withstands high pressure and temperature.

Performance Data: Detailed performance charts for various models are included, showing torque, speed, and flow rates under different conditions. Theoretical torque and efficiency ratings are provided, with intermittent ratings not exceeding 10% of operation time.

Typical Applications: WG series motors are suitable for conveyors, car washes, positioners, light to medium-duty wheel drives, sweepers, grain augers, spreaders, feed rollers, screw drives, and brush drives.

Displacement Performance: Performance data is typical and may vary slightly between production units. Detailed charts for displacement performance are provided, showing torque and speed at various flow rates and pressures.

Specifications:

Displacement Options: Ranges from 41 cm³/rev [2.5 in³/rev] to 404 cm³/rev [24.4 in³/rev].
Mounting Options: Includes 2-Hole and 4-Hole configurations with various port alignments and sizes.
Shaft Options: Available in different sizes and configurations, including straight and tapered shafts.
Paint Options: Standard black and black with unpainted mounting surface.
Valve Cavity/Cartridge Options: Various options available for customization.
Additional Features: Speed sensors, free-turning rotors, and other add-ons.

Procedures:

Ordering Process: Involves selecting series designation, displacement, mount & port option, shaft option, paint option, valve cavity/cartridge option, add-on option, and miscellaneous option.

Technical Information:

Dimensions: Detailed dimensions provided for housing and shafts, with considerations for paint thickness.
Weight: Motor weights vary based on configurations, with a detailed weight chart provided.
Rotation: Motors are bi-directional, with instructions for prolonging shaft seal life in unidirectional applications.

Recommendations:

For applications requiring unidirectional rotation, pressurize the A port to extend shaft seal life.

Contact Information: White Drive Products provides contact details for their offices in North America, Europe, and Asia.
