Robust Performance for High Cycle, Torque Demanding Applications

Helac Cut-Away

Ideal for applications where torque generation and higher cycle rates are the primary requirements, the T20 Series features splined output shafts and 200-220 degrees of rotation. Helac's helical, sliding spline technology is non self-locking while providing high shock resistance and high-holding torque for demanding applications.

Functioning as a rotating device, mounting bracket and load bearing structure the T20 Series eliminates the need for external bearing systems, brakes or locking devices. Three standard sizes with torque output up to 60,000 in-lbs at 3,000 psi (6,780 Nm at 210 bar).
