Product catalog summary

Specifications
The HB Series hydraulic motor is engineered for medium-duty applications, emphasizing high efficiency and durability. It features a three-zone orbiting valve, laminated manifold, and Roller Stator® motor, ensuring high efficiency across various conditions. A standard case drain is included to prolong shaft seal life by reducing internal pressures, with an optional internal drain. The heavy-duty drivelink offers 30% more torque capacity than competitors, suitable for continuous operations requiring peak efficiency.

Overview
The motor includes forced drive link lubrication to minimize wear and extend lifespan. The robust drive link surpasses competitive designs in strength, and the three-zone orbiting valve provides excellent volumetric efficiency. A rubber-energized steel face seal endures high pressure and temperature without damage.

Series Descriptions
Performance data is typical and may vary slightly between units. Intermittent ratings should not exceed 10% of operation time. Applications include conveyors, carwashes, positioners, light-duty wheel drives, sweepers, machine tool indexers, grain augers, spreaders, feed rollers, screw drives, and brush drives.

Performance Data
Detailed performance data for various models includes maximum speed, flow, torque, and pressure. For instance, the 050 model achieves a maximum speed of 52 rpm, a flow of 3.2 lpm, and a torque of 680 Nm at 830 bar. Data is presented in tables with continuous, intermittent, and peak values for each model.

Displacement Performance
Performance data varies slightly between motors. Theoretical torque and speed are provided for different displacements, with efficiency categorized into three ranges: 70-100%, 40-69%, and 0-39%. Intermittent ratings are limited to 10% of operation time, tested at 54°C with an oil viscosity of 46cSt.

Specifications:
Detailed specifications for HB (300 and 310 Series) and HK (315 Series) motors and brakes include maximum torque values for different shaft types, ranging from 170 Nm to 1130 Nm. Motors are bi-directional, allowing reversible shaft rotation by reversing the inlet hose.

Procedures:
The document outlines the ordering process for hydraulic motors and brakes, detailing steps to select series designation, displacement options, mount type, port size, shaft option, paint option, valve cavity/cartridge option, add-on options, and miscellaneous options.

Standards and Norms
Porting options and housing dimensions are specified, with paint thickness considerations. Bearing load curves are based on ISO 281 bearing capacity for an L10 life of 2,000 hours at 100 rpm.

Recommendations
Recommendations include selecting appropriate shaft options and paint finishes based on application needs. The document advises on using speed sensors with specific extended shafts and provides guidelines for valve cavity availability.

Key Data from Tables and Charts
Tables list displacement options in cm3/rev and in3/rev, torque values, and weight and length charts for different motor series. Bearing load curves for different motor configurations are also provided.

Critical Information
Critical information includes maximum torque values, displacement options, and the importance of selecting the correct mount type and port size for specific applications. Proper selection of valve relief pressures and valve cavity availability on specific ports is emphasized.

For Medium Duty Applications The HB Series motor is the leader in its class, offering high efficiency and durability. The three-zone orbiting valve, laminated manifold and Roller Stator® motor work harmoni- ously to produce high overall efficiencies over a wide range of operating conditions. The standard case drain increases shaft seal life by reducing internal pressures experienced by the seal. Case oil leakage is also directed across all driveline components, increasing motor life. An internal drain option is also available. At the heart of the motor is a heavy-duty drivelink, offering 30%...
