About the Airtac SC32 Standard Cylinder SC32X400
The SC32X400 is a compact double-acting pneumatic cylinder delivering 402 N of push force at 0.5 MPa (724 N at 0.9 MPa). Its 12 mm diameter piston rod and 21 mm air cushion provide reliable deceleration for mid-stroke applications.
With a 400 mm stroke and a body length of 140 mm, this genuine AirTAC actuator suits automated equipment needing a moderate reach. The tie-rod construction keeps it serviceable, while PT1/8 ports ensure straightforward pneumatic connections.

Where the Airtac SC32 Standard Cylinder SC32X400 Is Used
Conveyor Diverting
Operates sorting gates and diverter arms on light-duty packaging conveyors, leveraging the 400 mm stroke for extended reach.
Assembly Clamping
Provides the push-pull action for clamping small components in CNC drilling or light assembly fixtures, using the 402 N force at standard line pressure.
Lab Automation
Actuates dispensing nozzles or test actuators in lab automation where a clean, compact 32 mm bore cylinder with adjustable cushioning is essential.
Is the Airtac SC32 Standard Cylinder SC32X400 the Right Cylinder?
For applications needing more force, step up to the SC40 bore which provides 628 N at 0.5 MPa. At 400 mm of stroke, ensure the 12 mm rod is not subjected to significant side loading; an external guide rail is recommended to prevent rod bending and premature seal wear. When replacing an existing cylinder, match the 32 mm bore, 400 mm stroke, PT port thread, basic mounting, and confirm whether a magnet is required for sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC32 Standard Cylinder SC32X400 FAQ
At the standard operating pressure of 0.5 MPa, the SC32X400 generates 402 N of force when extending and 345 N when retracting. At the maximum operating pressure of 0.9 MPa, the extending force increases to 724 N.
This is a tie-rod cylinder, not an ISO 15552 profile cylinder. It is dimensionally shorter. To guarantee a correct replacement, you must match the 32 mm bore, 400 mm stroke, PT port thread, and basic mounting style. Check if your original unit had a magnet for sensors.
