The Luobai rack & pinion pneumatic actuator produces linear torque output in a compact design utilizing the same body and end caps for double-acting and spring-return units.

The standard angle of rotation is 90°. Luobai actuators feature dual travel stops that provide ± 10° stroke rotation on both the opening and closing phases of the actuator stroke. 110° of travel in a standard 90° actuator!

Extruded aluminum body is internally machined and honed to exact specifications. Honing prevents dry spots from forming within the actuator bore and therefore eliminates premature seal failure—a critical aspect to long cycle-life. All internal and external surfaces are hard anodized for corrosion resistance, with all units permanently lubricated at the factory.

Shaft bearings isolate the pinion gear from the housing and support the shaft for high-cycle applications. Many competitive manufacturers do not provide this critical feature.

Pistons incorporate double wear pads (skates) to separate the rack from the actuator wall and serve as both guide and wear bearings.
