The Parker TG Series Hydraulic Motor stands as a solid low-speed, high-torque (LSHT) gerotor motor built for medium-duty industrial jobs. Known for its tough build and steady output, this Torqmotor™ series brings reliable power in rough settings where constant torque at slow speeds matters most.
Parker TG Series Hydraulic Motor Core Technical Specifications
The Parker TG Series covers 14 displacement sizes from 141 cm³/rev to 959 cm³/rev (8.6 to 58.5 in³/rev). Models include TG0140, TG0170, TG0195, TG0240, TG0280, TG0310, TG0335, TG0405, TG0475, TG0530, TG0625, TG0785, and TG0960. Continuous pressure reaches 207 bar (3000 psi), with short bursts up to 276-280 bar (4000 psi) based on setup.
Max continuous flow hits up to 76 L/min (20 gpm), short bursts to 95-114 L/min (25-30 gpm). Speeds top out near 660 rpm. Output torque goes as high as 1490 Nm (13,000 lb-in) for short periods, with steady numbers often between 773-1268 Nm across models. Starting torque stays strong, usually 70-90% of running torque. This ensures dependable startup under load.
These numbers place the TG Series as a flexible choice for medium-duty tasks. It balances torque strength with smooth running.
Displacement Range and Model Selection Guide
Choosing the right displacement improves system work. Smaller sizes (e.g., TG0140 at 141 cm³/rev) fit higher-speed, lower-torque needs. Larger ones (e.g., TG0960 at 959 cm³/rev) deliver max torque for heavy pull or turn jobs. Model codes include shaft type (keyed, splined), mounting (flange or wheel), porting (SAE, NPT), and rotation direction. This allows exact match to equipment needs.
Patented Design Innovations for Enhanced Reliability
The TG Series uses several patented parts that set it apart in industrial hydraulics.
Patented 60:40 Spline Geometry in Torque Link
At the heart sits the extra heavy-duty torque link (drive link) with special 60:40 spline shape. This design carries higher torque loads with less weight and reduced spline wear compared to usual 50:50 setups. It adds longer life under repeated loading.
Roller Vanes and Sealed Commutator System
Roller vanes lower inside friction and leaks. This keeps flow efficiency over time. The orbiting commutator, paired with a sealed build, cuts wear at low speeds. It gives smooth torque with little ripple.
Continuous High-Flow Fluid Circulation
The powertrain gets steady washing by cool, high-flow hydraulic fluid. This spreads heat and clears dirt from key splines and bearings. The inside cooling system greatly boosts life in long-run cycles.
High-Pressure Shaft Seal and Bearing Configuration
A strong high-pressure shaft seal removes the need for case drain in most setups. This simplifies install and cuts plumbing work. Heavy-duty thrust and roller bearings support high side-load strength—up to 3600 lb (16013 N) dynamic at the key—often twice prior models. This makes the motor tough against side forces from chains, belts, or hanging loads.
Superior Side Load and Durability Advantages
Industrial spots often bring side loads from off-center placement, belt pull, or machine moves. The TG Series handles this with outstanding bearing design and shaft seal strength. It keeps running where weaker motors break early. Strong housing and manifold build further guard against shock loads and dirt.
Smooth Low-Speed Operation and Efficiency Profile
Very smooth low-speed running comes from reduced cogging and exact commutation. This trait proves key in jobs needing fine control, like positioning or variable-speed drives. High starting efficiency and low torque ripple cut shake sent to connected gear. This improves system steadiness and operator comfort.
Mounting and Configuration Flexibility
Available in flange (SAE A/B patterns) and wheel mounts, the series fits many setup needs. Shaft choices include keyed (up to 1.375-inch nominal), splined (14-tooth or 17-tooth), and tapered up to 34.9 mm. Porting supports standard SAE straight-thread or NPT setups, with bidirectional work standard.
This flexibility allows easy swap or upgrade in existing systems across world industrial fleets.
Parker TG Series Hydraulic Motor Application-Specific Performance in Key Sectors
Construction and Material Handling Equipment
In skid steers, cranes, and conveyors, the TG Series gives steady boom turn, winch work, and drive. High starting torque handles startup loads, while strong side-load strength stands up to off-center forces.
Agricultural Machinery
Harvesters, sprayers, and chain-driven tools benefit from smooth low-speed work and shake reduction. The motor’s efficiency cuts heat during long field runs.
Forestry and Mining Applications
Grapples, loaders, and drilling rigs use the tough build and high short pressure for hard cycles. Steady fluid cooling keeps performance in dusty, hot conditions.
Industrial Automation and Vehicle Systems
Factory lines, turf gear, and special vehicles use the motor’s exactness and lasting power for steady output in repeat tasks.
