Product Overview
The Parker Torqmotor™ TE Series is a light-duty low-speed, high-torque (LSHT) orbital hydraulic motor featuring an inlaid-column Geroler gear set with a patented commutation system. It spans displacements from 36 to 392 cm³/rev, with intermittent pressure ratings up to 190 bar (2,750 psi), intermittent torque up to 648 Nm (5,728 lb-in), and maximum speeds reaching 1,141 rpm. The TE Series is the only motor in its class with roller bearings, carrying up to 6,672 N dynamic side load at the key and withstanding the pounding delivered by chain and sprocket couplings.
The three core models covered herein — TE0100CW261LAAC (98 cm³/rev), TE0165CW690AAAA (163 cm³/rev), and TE0195CN410AAAB (195 cm³/rev) — are manufactured to Parker OEM specifications with 100% drop-in interchangeability. Mounting flange dimensions, shaft specifications, and port configurations correspond exactly to genuine Parker products, requiring no modification to piping or drivetrain interfaces. Every unit undergoes 100% simulated duty-cycle testing before shipment, verifying volumetric efficiency, torque output, and seal integrity. The TE Series features a standard high-pressure shaft seal, and its innovative design eliminates the need for a case drain line, simplifying system layout and reducing potential leak paths. Designed and manufactured in Greeneville, TN USA, every unit undergoes rigorous quality inspection before shipment.

Key Technical Advantages
1. Only Roller-Bearing Configuration in Its Class — Superior Side Load Capacity
The TE Series is the only motor in its class with roller bearings, carrying up to 6,672 N (1,500 lb) maximum dynamic side load at the key. From an engineering standpoint, the line contact of roller bearings versus the point contact of ball bearings provides a larger contact area and higher load capacity when subjected to radial loads. This advantage allows the TE Series to directly drive sprockets or gears without additional bearing support structures, significantly reducing total drivetrain cost in chain and sprocket coupling applications.
2. High-Pressure Shaft Seal with Innovative Case-Drain-Free Design
The TE Series features a standard high-pressure shaft seal rated for intermittent pressures up to 190 bar, while its innovative design eliminates the need for an external case drain line. From a system integration perspective, the case-drain-free design reduces plumbing complexity and minimizes potential leak points. For replacement applications, this means no additional drain ports are required on the host machine, directly reducing installation time and maintenance costs. The high-pressure shaft seal operates under high-flow cooling fluid wash, effectively extending seal life.
3. Continuous Oil Flow Spline Lubrication
The TE Series incorporates internal continuous oil flow channels that constantly flush and lubricate the internal spline pairs during operation. From an engineering standpoint, this mechanism keeps the spline pair operating at low temperatures, preventing material degradation and clearance growth caused by localized overheating. The continuous cooling and lubrication of the spline pair is a key factor behind the TE Series’ long-life reliable operation, particularly suited to applications involving frequent starts/stops and high-frequency alternating loads.
4. Patented Commutation System with Roller Vane Rotor Design
The TE Series employs a zero-leak commutation valve plate system in which the commutation process involves no sliding friction, significantly reducing wear rates. Combined with a roller vane rotor design, internal friction and leakage are minimized, maintaining stable volumetric efficiency throughout the service life. The cast iron housing with precision-machined critical mating surfaces maintains stable clearances across a wide temperature range, ensuring efficient output even after extended operation.
5. Modular Platform with Broad Interchange Compatibility
The TE Series is built on a modular design platform spanning displacements from 36 to 392 cm³/rev, offering multiple flange options including SAE A 2-bolt diamond flange, SAE A 2-bolt magneto flange, 4-bolt mount, and wheel mount, along with cylindrical, splined (SAE 6B), and tapered shaft options. The TE Series enables drop-in interchange with Eaton Char-Lynn S Series, M+S MR Series, and other mainstream brand motors, delivering true drop-in interchangeability.

Expert Maintenance Tips
Installation Notes:
The TE0100CW261LAAC uses an SAE A 2-bolt diamond flange with a 25.4 mm cylindrical shaft. Verify the host machine’s flange pilot and bolt pattern match before installation, and ensure the pilot face is clean and free of debris.
The TE0165CW690AAAA uses an SAE A 2-bolt diamond flange with a 25.4 mm cylindrical shaft. Apply a light coating of grease to the shaft and keyway before assembly to prevent corrosion and ensure smooth engagement.
The TE0195CN410AAAB uses an SAE A 2-bolt diamond flange with a 25.4 mm splined shaft (6-tooth). Apply a light coating of grease to the spline surface before assembly to prevent corrosion and ensure smooth engagement with the coupling or hub.
All models use 7/8″-14 SAE ports. Use appropriate sealing washers during installation and avoid over-torquing to prevent thread damage.
The TE Series features a standard high-pressure shaft seal with case-drain-free design. However, ensure that return back-pressure does not exceed shaft seal limits (maximum intermittent pressure 190 bar).
Operation & Maintenance:
Replace the hydraulic oil filter after the first 50 hours of operation and verify fluid cleanliness to ISO 4406 class 20/18/15 or better.
Recommended oil viscosity range is 20–75 mm²/s; maintain normal operating oil temperature between 20°C and 60°C.
After installation, run the new motor at 30% of rated pressure or less for at least 1 hour for run-in before gradually loading to rated conditions.
Periodically check flange bolt torque. Re-torque every 500 hours to prevent loosening caused by vibration.
After extended storage, run the motor at low speed and light load for 10–15 minutes to re-establish the internal oil film before gradually applying full load.
