TF0170 Parker Torqmotor TF Series Hydraulic Motor 169cc 3000 PSI

Product Overview

The TF0170 is a medium-duty low-speed, high-torque orbital hydraulic motor from Parker’s Torqmotor™ TF Series. Featuring a Gerotor gear set and cast iron housing, this motor delivers a displacement of 169 cm³/rev (10.3 in³/rev), with a maximum continuous pressure differential of 138 bar (2000 PSID) and intermittent capability up to 207 bar (3000 PSID). Maximum speed is 444 RPM, with continuous output torque of 317 Nm (2808 lb-in) and intermittent torque up to 489 Nm (4324 lb-in).

The TF Series is distinguished by its innovative no-case-drain design, high-pressure shaft seal, and patented 60:40 spline geometry with continuous cool fluid flushing. These engineering features ensure superior side load capacity, smooth extra-low-speed operation, and extended service life in the most demanding applications.

This motor is manufactured to Parker Torqmotor™ TF Series original specifications and offers true drop-in interchangeability — it directly replaces TF0170HW410BBBN, TF0100AM050AAAA, and other TF Series models without any modification to mounting interfaces or port connections. Every unit undergoes 100% simulated working-condition testing before shipment, validating flow, pressure, speed, torque, and leakage performance.

Key Technical Advantages

1. Patented 60:40 Spline Geometry
   The TF Series powertrain utilizes Parker’s patented 60:40 spline geometry for superior strength and load distribution. All internal splines are continuously flushed with cool fluid, reducing operating temperatures and extending drivetrain service life.

2. High-Pressure Shaft Seal with No Case Drain Required
   The TF Series features a standard high-pressure shaft seal capable of withstanding full system pressure. Its innovative design eliminates the need for a case drain line, simplifying system plumbing and reducing potential leak points.

3. Superior Side Load Capacity
   The TF Series bearing system is optimized to carry up to 17792 N side load on flange mounts and 26688 N on wheel mounts. This enables direct mounting of pulleys, sprockets, or wheels without additional bearing support structures, simplifying drivetrain design.

4. High Volumetric Efficiency with Roller Vane & Sealed Commutation
   The roller vane and sealed commutation design ensures high volumetric efficiency and smooth low-speed operation. The motor maintains consistent torque output even at extremely low speeds, effectively preventing stick-slip behavior.

5. Cast Iron Housing & Robust Construction
   The cast iron housing provides superior structural rigidity and deformation resistance, making the TF Series suitable for the most severe operating environments including mining, forestry, and construction equipment applications.

6. Compact Design with High Power Density
   Delivering 317 Nm of continuous torque from a 169 cm³/rev displacement, the TF0170 achieves a power density that leads its class of orbital motors. The standard 31.75 mm shaft diameter balances load-carrying capability with compact installation dimensions.

Application Areas

• Material Handling: Conveyor drives, winches, boom rotate mechanisms

• Industrial Equipment: Injection mold compression drives, specialty harvesters (potato, tomato, nut, leafy vegetable, sugar, cotton, coffee, grape)

• Oil & Gas: Blender truck drives

• Marine & Offshore: Ship winches, offshore cranes

Expert Maintenance Tips

1. Pre-Installation Fluid Cleanliness Check: Verify system oil cleanliness meets ISO 4406 18/16/13 or better before installation. Install a 10 μm or finer return-line filter to prevent particulate contamination from entering the motor and causing Gerotor wear.

2. No Case Drain Line Required: The TF Series motor requires no case drain line, simplifying system layout. However, ensure the shaft seal is not subjected to back pressure exceeding rated values.

3. Initial Start-Up Bleeding: After first installation or motor replacement, operate at low pressure (not exceeding 50 bar) for 5–10 minutes to bleed air from the system. Confirm no cavitation noise is present before gradually increasing to working pressure. Never apply full load before proper bleeding.

4. Oil Temperature Control: Maintain hydraulic oil temperature between 30°C and 60°C during continuous operation. Sustained temperatures above 80°C will accelerate seal degradation and reduce oil viscosity, leading to decreased volumetric efficiency.

5. Side Load Monitoring: If the output shaft directly carries radial loads (e.g., sprocket or pulley drives), periodically inspect the shaft seal area for leakage. Side loads exceeding rated values will accelerate bearing wear and shaft seal failure.

6. Bolt Torque Re-Check: Re-torque mounting bolts at 50-hour and 500-hour service intervals to ensure fastening torque meets Parker specifications and prevents loosening caused by vibration.
