Product Overview
The Parker TE Series Torqmotor™ is a medium-duty low-speed high-torque (LSHT) gerotor hydraulic motor platform from Parker Hannifin, featuring an advanced Geroler gear set with a roller-type rotor design that maintains high volumetric efficiency and stable operation even at low speeds. The TE Series is the only motor in its class with roller bearings, capable of handling side loads up to 1,500 lb (6,650 N) and withstanding the pounding delivered by chain and sprocket couplings. With higher pressure ratings than the TB Series, the TE Series is ideal for medium-torque applications.
The specific models covered in this document — TE0130CW260LAAY, TE0330CW260AAAB, TE0100AS130AAAB, and TE0230AP100AAAA — span the core displacement range of the TE Series from 98 cm³/rev to 328 cm³/rev. All models are manufactured to original Parker specifications with 100% drop-in interchangeability, requiring no modification to mounting interfaces, port positions, or hydraulic connections. Every unit undergoes 100% simulated operating condition testing at the factory, including rated pressure loading, volumetric efficiency verification, seal integrity assessment, and low-speed smoothness validation prior to shipment.

Key Technical Advantages
1. Geroler Rotor Set with Roller-Type Construction
The TE Series employs an advanced Geroler gear set with an integrated roller-type rotor design rather than conventional fixed tooth profiles. The rollers substitute rolling friction for sliding friction during rotor movement, significantly reducing friction resistance and wear rates in the running gear. The engineering significance of this design lies in its ability to maintain stable oil film load-bearing capacity at low speeds, reducing stick-slip phenomena. Meanwhile, the roller structure offers better tolerance to microscopic particles in hydraulic fluid, reducing the risk of jamming due to contamination. Through this construction, the TE Series achieves high volumetric efficiency and long service life under low-speed high-torque operating conditions.
2. Roller Bearings with High Side Load Capacity
The TE Series is the only LSHT motor series in its class equipped with roller bearings, with a maximum side load capacity of 6,650 N (1,500 lb), accommodating dynamic shock loads transmitted by chain and sprocket couplings. The engineering advantage of this bearing configuration lies in its ability to directly absorb radial forces generated by driven components (sprockets, gears, pulleys) without requiring a separate bearing support housing — simplifying system design and reducing installation costs. Compared to sliding bearings, roller bearings offer higher load capacity and longer service life, performing particularly well under frequent start-stop and shock load conditions.
3. High Pressure Shaft Seal with Case Drain-Free Design
The TE Series features a standard high-pressure shaft seal with an innovative design that eliminates the need for a case drain line. In conventional hydraulic motors, the case drain line routes internal leakage back to the reservoir and carries away heat. The TE Series shaft seal design withstands higher case pressures and maintains internal leakage at extremely low levels, eliminating dependence on a separate drain line. The engineering value of this design includes: reduced hose and fitting count, lowering system cost and leakage risk; simplified installation layout, particularly advantageous in space-constrained mobile machinery; and reduced maintenance points, improving system reliability.
4. High Flow Shaft Seal Cooling and Long-Life Design
The TE Series features high flow shaft seal cooling, optimizing the oil circulation path around the shaft seal to effectively remove friction-generated heat and extend shaft seal service life. The motor also features a high-strength cast iron housing combined with precision valve plate design, delivering smooth low-speed operation and low noise output across the full speed range. Available options for the TE Series include multiple mounting flanges, shaft configurations, port specifications, and rotation directions, providing flexible adaptation for system integration.

Expert Maintenance Tips
1. Fluid Cleanliness Management
The TE Series operates with micron-level clearances in the Geroler rotor set and valve plate working surfaces. Particulate contamination in hydraulic fluid is the leading cause of rotor set wear and valve plate scoring. Systems must be equipped with filtration rated to ISO 4406 18/16/13 or better. Replace filter elements at the first 500-hour interval, then every 1,000–2,000 hours or based on oil analysis results. In high-contamination environments such as agricultural or municipal job sites, consider shortening fluid change intervals accordingly.
2. Case Drain-Free Installation Advantages and Precautions
The TE Series features a standard high-pressure shaft seal and requires no case drain line, allowing direct connection into the system without additional drain plumbing. However, note that although no drain line is required, the motor housing is still equipped with a drain port, which should be used for case filling and air purging after service or extended shutdown. If system back pressure exceeds the shaft seal rated capacity, a case drain line should still be considered to protect the shaft seal.
3. Pre-Start Case Filling and Air Purging
Before first startup after installation or repair, fill the case through the highest drain port until fluid overflows. The TE Series Geroler rotor set creates a complex internal cavity geometry; starting an un-purged motor can cause dry friction damage between the rotor set and valve plate. For drain-free installations, retighten the drain plug after filling and confirm no external leakage before startup.
4. Output Shaft and Mounting Alignment
The TE Series uses SAE standard flange mounting with a keyed output shaft. During installation, verify that the output shaft is properly aligned with the mating component, and that keyway engagement length meets design requirements. Installation misalignment will cause abnormal keyway wear and bearing side loading, significantly shortening service life. For applications with sprockets or gears directly mounted on the motor shaft, ensure proper chain tension to avoid excessive radial forces exceeding the bearing load capacity.
5. Side Load Control
The TE Series maximum side load capacity is 6,650 N (1,500 lb). In application, ensure that radial forces generated by driven components (sprockets, gears, pulleys) do not exceed this limit. If the drive ratio or transmission method results in side loads exceeding specifications, redesign the drive layout or add auxiliary support bearings. Inspect mounting bolt torque and output shaft keyway wear every 500 operating hours.
6. Restart Procedure After Extended Shutdown
If the motor has been idle for more than three months, manually rotate the output shaft to confirm freedom of movement, and inspect the case oil level and shaft seal for leakage before restarting. Extended shutdown can cause oil film drainage from rotor set interfaces, creating a dry-start risk. Before restarting, replenish clean hydraulic fluid through the case fill port and operate at low speed and reduced load for 10–15 minutes before returning to normal duty.
