Hydraulic rotary actuators

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.
