Description

Overview
The Kawasaki rotary actuator converts hydraulic pressure into reciprocating rotary motion over an arc up to 280° total travel, eliminating the need for complex external linkages. Special variants are available with outer stoppers and buffer valves for controlled end-of-travel behavior.

Features

Provides large torque without cumbersome linkage mechanisms.
Available in special types with outer stopper and buffer valve for end-position control.
