Product Description

Product Overview

The TG/TH Series Orbital Hydraulic Motor (Torqmotor™) is Parker Hannifin’s medium-to-heavy duty, low-speed high-torque (LSHT) fixed-displacement hydraulic actuator family, covering a comprehensive displacement spectrum from 141 cm³/rev to 959 cm³/rev. The series features a patented Roller Vane Rotor mechanism with Sealed Commutation design, efficiently converting hydraulic pressure and flow into high-torque, low-speed rotational mechanical power.

Designed as a direct drop-in replacement for industry-leading brands, the TG/TH series guarantees full dimensional interchangeability across flange mounting patterns, port configurations, and shaft dimensions:

TG/TH Series ↔ Danfoss OMS Series, Eaton Char-Lynn 2000 Series, M+S MS/MSY/MLHS Series, White RE Series, Sambrenivi HPR/MGS/GMS Series

The TG series features standard flange mounting, while the TH series utilizes wheel mount configuration — both share identical powertrain core components, differing only in housing mounting interface and port layout. Every unit undergoes 100% simulated working condition testing prior to shipment, encompassing full-load running at rated pressure, high/low speed response verification, internal leakage quantification, and starting torque validation.

The innovative design eliminates the need for a case drain line, with a high-pressure shaft seal as standard configuration, enabling direct deployment in series circuits or high back-pressure open-loop systems, significantly simplifying piping architecture.

Key Technical Advantages

Patented Roller Vane Rotor Mechanism — Low Friction, Extended Service Life
The heart of the TG/TH series powertrain is its patented Roller Vane rotor mechanism. Unlike conventional sliding vane designs, the roller vanes operate with rolling contact against the stator profile, converting sliding friction into rolling friction. This dramatically reduces mechanical losses and wear rates, significantly extending service life compared to conventional orbital motors while maintaining high volumetric efficiency with minimal internal leakage.

Patented 60:40 Spline Geometry — Higher Torque Density & Structural Strength
The powertrain employs a patented 60:40 internal/external spline geometry (60% external / 40% internal), transmitting more torque at less weight compared to traditional equal-ratio splines. All spline surfaces are continuously flushed with cooling oil, ensuring durability and fatigue resistance under heavy-load conditions. This design enables the TG/TH series to deliver up to 1,268 N·m (11,227 lb-in) of intermittent torque through a 1.25″ shaft.

Innovative Case-Drain-Free Design — Simplified Plumbing, Reduced Installation Cost
The TG/TH series comes standard with a patented high-pressure shaft seal system that allows the motor to operate without a case drain line. This innovative design eliminates the traditional requirement for external drain plumbing on orbital motors, dramatically simplifying hydraulic system piping layouts, reducing leak points, and cutting installation labor. The shaft seal withstands full system pressure and is continuously washed and cooled by the hydraulic fluid, ensuring long-lasting seal performance.

Superior Side Load Capacity — Direct Drive Without Auxiliary Support
The TG/TH series can withstand up to 16,013 N (3,597 lb) of dynamic side load at the key, with wheel mount versions (TH series) rated for up to 6,000 lb. This enables direct driving of sprockets, sheaves, augers, or wheels as cantilevered loads without auxiliary support bearing blocks, significantly reducing system complexity and total cost of ownership.

Ultra-Low Speed Smooth Operation — Stick-Slip Free Precision Control
Through Sealed Commutation technology and precision-matched distribution components, the TG/TH series delivers smooth torque output at extremely low speeds (as low as 1-5 rpm) without stick-slip crawling. This makes it particularly suitable for winches, boom rotation, feed drives, and other applications requiring precise low-speed control.

Expert Maintenance Tips

Critical Initial Break-In Procedure:
After installation, the motor housing must be completely filled with clean hydraulic oil through the work ports before startup. Manually rotate the output shaft to confirm freedom of movement. The initial run must proceed unloaded at no more than 30% of rated pressure for approximately 1 hour to purge air and initiate break-in, allowing the roller vanes and stator profile to achieve proper micro-surface mating. Under no circumstances should load be applied before ensuring the motor is fully oil-filled.

Hydraulic Fluid Cleanliness Management:
Use SAE 10W40 SE or SF grade hydraulic oil with viscosity not below 13 cSt at operating temperature. Fluid cleanliness must be strictly maintained at ISO 4406: 18/13 or better. Install a minimum 30-micron filter in the system return line. Replace hydraulic oil and clean the filter after the first 200 operating hours, then follow a regular interval of every 2,000 hours or annually (whichever comes first). Maximum operating oil temperature: 80°C.

Case-Drain-Free Operation Considerations:
The TG/TH series’ innovative design allows operation without an external case drain under normal conditions. However, when system return back pressure continuously exceeds recommended values, or when motors operate in series/parallel circuits, connecting an external drain line is recommended to extend shaft seal life and evacuate wear particles. Minimum drain line size: 3/8″; avoid high points in the drain line routing that could trap air. The drain line must return independently — never in series with the main return line.

Installation Coaxiality & Side Load Management:
Maintain strict coaxiality (deviation ≤0.05 mm) between the motor output shaft and the driven load coupling. Excessive misalignment generates parasitic radial forces that accelerate bearing and seal wear. While the TG/TH series offers exceptional side load capacity (up to 16,013 N dynamic at the key), avoid sustained operation at side load conditions. Prioritize flange-mounted installation for optimal alignment. All connected piping must be stress-free — no external pipe forces should act upon the motor ports.

Bearing Replacement Notes (TH Series Specific):
TH series motors require a special bearing mandrel tool (1.575″ / 40.0 mm and 2.130″ / 54.1 mm sizes) for bearing removal and installation during service. When replacing bearings, only Parker-specified grease (Parker Specification #045236 or Mobil Mobilith SHC® 460) must be used — never substitute with standard lithium-based grease. After assembly, verify commutation clearance with a 0.005″ (0.13 mm) feeler gauge.
