The AirTAC Airtac SC32 Standard Cylinder SC32X425 is a genuine double-acting standard air cylinder with a Ø32mm bore and 425mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X425 is a compact double-acting pneumatic cylinder from the AirTAC SC tie-rod series, pairing a 32 mm bore with a 425 mm stroke. It generates 402 N of push force and 345 N of pull force when operated at 0.5 MPa, making it a capable actuator for light-to-medium automation tasks where space is limited.
This model features a 12 mm diameter piston rod with an M10x1.25 thread and PT1/8 ports. The total extended body length is approximately 565 mm, based on the 140 mm body length A plus the stroke. Its 21 mm adjustable air cushion at each end helps decelerate the piston smoothly, reducing end-of-stroke impact for consistent cycling.

Provides the quick, repetitive linear motion needed to eject lightweight plastic or metal components from assembly fixtures and pick-and-place stations.
Operates a small diverter gate on a packaging conveyor line, reliably sorting products with its 402 N push force at standard shop air pressure.
Drives a linear sampling mechanism in a diagnostic or chemical analyzer, where the compact 32 mm bore footprint and clean, filtered air operation are essential.
For applications requiring slightly more force, stepping up to the 40 mm bore SC40 series provides 628 N of push force at 0.5 MPa. When replacing an existing cylinder, ensure a precise match across five key points: bore (32 mm), stroke (425 mm), port thread (PT1/8), mounting style (basic), and the presence of a magnet (none on this model).
At a 425 mm stroke, the 12 mm rod is relatively slender. If the load is not guided externally or if side forces are present, consider adding an external linear guide or switching to a guided cylinder to prevent rod bending and premature bearing wear.
Quick checklist
At the standard operating pressure of 0.7 MPa, the push force is 563 N and the pull force is 483 N. The maximum theoretical push force at 1.0 MPa is 804 N (82 kgf).
No. The SC32X425 is a double-acting cylinder and will drift or drop its load if air pressure is exhausted or lost. To hold a position without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
