TG0195 Parker Gerotor Hydraulic Motor 195 cc/rev

Product Overview

The Parker TG0195 is a fixed-displacement Gerotor / LSHT orbital hydraulic motor engineered for low-speed, high-torque hydraulic drive applications. According to Parker’s official TG technical documentation, TG0195 has a geometric displacement of 195 cm³/rev (11.9 in³/rev), a maximum operating speed of 477 rpm, a maximum continuous differential pressure of 207 bar, and a maximum intermittent differential pressure of 276 bar. Maximum supply pressure is 300 bar.

Unlike axial piston motors, TG motors use a Gerotor-based LSHT architecture. Parker highlights high efficiency, smooth low-speed performance, high side-load capability, heavy-duty torque transmission, continuous powertrain cooling and high-pressure shaft sealing as key design characteristics.

The supplied models include TG0195AB050AAAA, TG0335AB050AAAA and TG0240MW460AAAB. They represent different displacement classes and configuration codes, so complete ordering-code verification is essential for an interchangeable replacement.

For OEM replacement, MRO and hydraulic equipment refurbishment, our manufacturing approach focuses on critical interface dimensions, precision machining and 100% simulated working-condition testing.

Key Technical Advantages

Gerotor LSHT Architecture

The TG design provides a practical combination of low-speed control and high torque output. The TG0195 delivers up to 556 Nm continuous torque under its rated continuous differential-pressure condition, making it suitable for demanding rotary drives where high starting torque is required.

Roller Vanes and Sealed Commutator

Parker specifies roller vanes and a sealed commutator to maintain efficiency and support smooth low-speed motor operation.

Heavy-Duty Torque Link

The TG powertrain uses Parker’s heavy-duty torque link with 60:40 spline geometry. Parker states that the rugged TG drivetrain is capable of transmitting more than 13,000 lb-in of torque.

Continuous Powertrain Cooling

The entire TG powertrain is continuously washed with cool, high-flow hydraulic fluid. This helps manage internal heat and supports long service life under demanding operating cycles.

High Side-Load Capability

The TG platform is engineered for significant mechanical side loading, with Parker documentation indicating capability up to the 16,000 N class depending on configuration. Actual allowable loads must be evaluated using shaft geometry, load location, speed and bearing-life considerations.

High-Pressure Shaft Sealing

The TG architecture incorporates high-pressure shaft sealing and shaft-area cooling provisions to improve reliability around the rotating output shaft under demanding operating conditions.

Precision Interchangeable Replacement

For TG0195AB050AAAA, TG0335AB050AAAA and TG0240MW460AAAB, replacement quality depends on more than external dimensions. Critical engineering parameters include Gerotor clearances, commutator geometry, shaft concentricity, spline engagement, mounting location, port position and seal interfaces.

Application Areas

Typical applications include:

• Construction Machinery
• Wheel Drive Systems
• Agricultural Equipment
• Forestry Machinery
• Material Handling Equipment
• Conveyor Drives
• Hydraulic Winches
• Drilling Equipment
• Road Construction Machinery
• Mobile Hydraulic Equipment
• Rotary Drive Systems
• Auxiliary Swing and Boom Drives

The TG0240MW460AAAB is publicly described for applications including vehicle drive, ground drilling, chain drives, winches and swing mechanisms.

Expert Maintenance Tips

Verify the Complete Part Number

Do not select a replacement based solely on TG0195, TG0240 or TG0335. Always verify:

• Displacement
• Mounting
• Port configuration
• Shaft code
• Shaft geometry
• Rotation
• Seal configuration
• Mechanical loading

Verify Shaft Configuration

Parker’s TG ordering documentation identifies:

• 03: 1-1/4 in keyed shaft
• 05: 1-1/4 in 14-tooth spline
• 08: 1-1/4 in tapered shaft

Therefore, a shaft-code mismatch can make an apparently identical displacement motor mechanically incompatible.

Respect Continuous Pressure Ratings

For TG0195:

• 207 bar: continuous differential pressure
• 276 bar: intermittent differential pressure
• 300 bar: maximum supply pressure

The intermittent performance rating is limited to 10% of every minute, so the intermittent pressure must not be treated as a continuous operating limit.

Match Hydraulic Flow to Displacement

The maximum operating speeds are approximately:

• TG0195: 477 rpm
• TG0240: 393 rpm
• TG0335: 277 rpm

Pump flow should therefore be matched to the motor displacement and required operating speed rather than increased indiscriminately.

Control Mechanical Side Loading

For wheel, chain, sprocket and drilling applications, inspect shaft alignment, overhung loads, coupling geometry and bearing loading regularly. Mechanical loading can be a major determinant of motor life.

Commission Progressively

After replacement, fill and purge the circuit, verify rotation, start at low flow and pressure, inspect for leakage, and increase the hydraulic load progressively.
