Used Numatics Pneumatic Actuators

Overview

Pneumatic actuators convert compressed air into linear or rotary motion for valves, clamps, and machine elements. They’re valued for fast response, simplicity, and clean operation in environments where hydraulics or electrics aren’t ideal. When selecting an actuator, match stroke/torque, mounting, materials, and operating pressure to the application and check compatibility with existing controls and air supply.

FAQ

What should I check when buying a pneumatic actuator?

Verify stroke or torque, bore size, mounting type, port orientation, operating pressure range, materials, seal type, and compatibility with your control valves and air quality. For used units, inspect wear on rods and seals and ask for service history.

How do I prepare a pneumatic actuator for safe shipping?

Depressurize and lock the actuator, cap or plug ports, retract/protect rods, secure mounting brackets, and crate or palletize to prevent impact. Use a carrier experienced with precision industrial components and insure the shipment.

What regular maintenance does a pneumatic actuator need?

Maintain clean, dry, lubricated air with filters/regulators/lubricators, check and replace seals, inspect for leaks, verify alignment and mountings, and test cycle performance. Frequency depends on duty cycle and environment.
