Torqmotor™ TG/ TH/TL Series fea-
tures include:
• Roller vanes to reduce friction and internal
leakage and to maintain efficiency.
• 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
eliminates the need for case drains, check
valves and extra plumbing.
• A manifold designed to improve operating
efficiency.
• Heavy-duty thrust and roller bearings for
up to twice the side-load capacity to the
previous motor.
• Up to 1000 lbs. (453.6 kg) end-thrust
capacity in either direction.
• A design that is less sensitive to contami-
nation than competitive motors.
• Up to 49 horsepower output.
• Greater durability because of superior
lubrication and minimum drive spline wear.
•
Zero leak
commutation valve provides
greater, more consistent volumetric ef-
ficiency.
