Hydraulic rotary actuators

Rotary actuators replace multiple components and function as rotating device, mounting bracket, and bearing support, all in one.

Rotary actuators replace multiple components and function as rotating device, mounting bracket, and bearing support, all in one. They offer torque output of740,000 lb-in. at 3,000 psi. Integral-bearings carry high radial, thrust, and moment loads without additional external bearing support. They feature zero leakage, drift-free positioning, and high resilience to shock loading. They come in 180 and 360° standard rotations in a wide variety of mounting styles.
