Introduction
Parker 60 Series spring return (AC/AO) or double acting (AD) rack and pinion actuators are compact, simply designed devices
that are quality engineered to provide high torque outputs and a high cycle, trouble-free life.
A compact, dual opposed rack and pinion design and guide bａnd suspension combine to produce a symmetrically balanced,
center mount actuator. In addition, the actuator has a short powerful stroke, rapid response, and fully concentric operating
load capability which ensures optimum performance.
Features
• Three point suspension system uses carbon filled
PTFE guide bands for piston alignment and rack support
• Dual opposed piston design uses air pressure on
two pistons to deliver a balanced force to the pinion gear
• Patented balanced piston design results in even
distribution of bearing loads and eliminates piston tilting
• Multiple spring concept permits actuator use at
40 to 120 psig (2.8 to 8.3 bar) air supply requirements
• Suitable for use with dry or lubricated air, non-corrosive
gas, or light hydraulic oil
• Aluminum alloy body construction with two component
polyurethane coating
• Manual override
