Torqmotor™ TG/ TH/TL Series features
include:
• Roller vanes to reduce friction and internal
leakage and to maintain effi ciency.
• A patented orbiting commutation system for
less wear and longer life.
• A patented 60:40 arrangement of internal and
external spline members to transmit more torque
with less weight.
• A unique high-pressure shaft seal that elimi-
nates the need for case drains, check valves and
extra plumbing.
• A manifold designed to improve operating ef-
fi ciency.
• Heavy-duty thrust and roller bearings for up to
twice the side-load capacity to the previous mo-
tor.
• Up to 1000 lbs. (453.6 kg) end-thrust capacity
in either direction.
• A design that is less sensitive to contamination
than competitive motors.
• Up to 49 horsepower output.
• Greater durability because of superior lubrica-
tion and minimum drive spline wear.
• Zero leak commutation valve provides
greater, more consistent volumetric effi ciency.
Torqmotor™ TF Series features include:
• Heavy-duty thrust and roller bearings for up to
twice side-load capacity to the previous motor.
• Roller vanes to reduce friction and internal
leakage, and to maintain effi ciency.

• A unique manifold designed to improve operat-
ing effi ciency.
• Up to 1000 lbs. (453.6 kg) end-thrust capacity
in either direction.
• A design that is less sensitive to contamination
than competitive motors.
• Up to 36 horsepower output.
• Greater durability because of superior lubrica-
tion and minimum drive spline wear.
• Superior low speed performance.
• Zero leak commutation valve provides
greater, more consistent volumetric effi ciency.
