Product catalog summary
Overview: The document provides comprehensive technical specifications and features of the White Drive Products Medium Duty Hydraulic Motors and Brakes, specifically focusing on the RE Series. These motors are designed for medium-duty applications, offering a balance between cost and performance, particularly suitable for low flow, high pressure scenarios.
Key Features and Benefits:
  • High Pressure Shaft Seal: Enhances seal life and performance, eliminating the need for a case drain.
  • Three Bearing Options: Customizable load carrying capability to match application needs.
  • Heavy-Duty Drive Link: Provides durability and full flow lubrication for extended life.
  • Valve-In-Rotor Design: Ensures efficient oil distribution and reduces motor length.
  • Pressure-Compensated Balance Plate: Improves volumetric efficiency at low flows and high pressure.
Specifications: The document details various models (500-541) with specifications such as maximum speed, flow, torque, and pressure. Performance data is typical and may vary slightly between production units.
Typical Applications: These motors are used in medium-duty wheel drives, augers, mixers, winch drives, swing drives, grapple heads, feed rollers, and broom drives.
Performance Data: Detailed tables provide information on displacement, torque, speed, and flow for different models. Theoretical torque and efficiency ratings are included, with intermittent ratings not exceeding 10% of operation time.
Conclusion: The RE Series motors are versatile and can be configured with various mounting flanges and output shafts to suit a wide range of applications, offering a cost-effective solution for medium-duty hydraulic needs.
Technical Specifications and Options: The document also covers the RE series (520/521, 530/531, and 540/541) with information on connectors, speed sensors, valve cavities, displacement options, mounting and port options, shaft options, paint options, and additional features.
Procedures:
  • Selection Process: A step-by-step process for selecting the appropriate motor configuration, including series designation, displacement, mount and port options, shaft options, paint options, valve cavity/cartridge options, add-on options, and miscellaneous options.
Technical Information:
  • Mounting and Shaft Lengths: Detailed dimensions and weight charts for different motor configurations, including SAE A mounts and wheel mounts.
  • Bearing and Shaft Load: Bearing curves represent allowable loads based on ISO 281 standards for an L10 life of 2,000 hours at 100 rpm.
Recommendations:
  • Rotation Direction: Motors are bi-directional, and reversing the inlet hose will reverse shaft rotation. For applications requiring one-directional rotation, pressurizing the A port can prolong shaft seal life.
Additional Features:
  • Paint Options: Options include black, black with unpainted mounting surface, and no paint.
  • Shaft Options: Various shaft configurations are available, including straight, tapered, and splined shafts with specific torque capacities.

RE-2

For Medium Duty Applications RE Series motors offer the perfect compromise between price and performance by producing work horse power at a reasonable cost. Although these motors perform well in a wide range of applications, they are especially suited for low flow, high pressure applications. During startup, pressure causes the balance plate to flex toward the rotor, vastly improving volumetric efficiency. As the motor reaches operating pressure, the balance plate relaxes, allowing the rotor to turn freely which translates into higher mechanical efficiencies. Transmitting this power to the output...
