About the Airtac SC32 Standard Cylinder SC32X245
The SC32X245 is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at 0.9 MPa). With a 12 mm diameter piston rod and a 245 mm stroke, it suits light automation tasks where space is limited but reliable linear motion is essential.
This model features a 21 mm adjustable air cushion at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 140 mm, giving a total extended length of approximately 385 mm. PT1/8 ports and an M10x1.25 rod thread are standard.

Where the Airtac SC32 Standard Cylinder SC32X245 Is Used
Small Part Ejection
The 402 N push force at 0.5 MPa is ideal for ejecting lightweight plastic or metal parts from injection molds or stamping dies, where the 245 mm stroke provides ample reach.
Diverter Gates
Actuates small diverter gates on conveyor lines. The adjustable cushion protects the gate mechanism from shock, while the 12 mm rod handles the repetitive side loads of light product sorting.
Lab Automation
Suitable for positioning pipettes or test tube racks in diagnostic equipment. The compact 140 mm body length plus stroke fits easily into benchtop devices, and the filtered air operation meets cleanroom requirements.
Is the Airtac SC32 Standard Cylinder SC32X245 the Right Cylinder?
For applications needing more force, stepping up to the 40 mm bore SC40 series provides 628 N push at 0.5 MPa. If a shorter stroke suffices, the SC32X200 reduces the overall envelope. This 245 mm stroke is within the 1000 mm maximum standard stroke for the 32 mm bore.
When replacing an existing cylinder, match five points: 32 mm bore, 245 mm stroke, PT1/8 port thread, basic mounting (no accessory bracket), and no magnet. This SC series is a tie-rod design, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC32 tie-rod cylinders.
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 SC32X245 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N. The theoretical maximum force at 1.0 MPa is 82 kgf.
No. The SC32X245 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift. For load holding, you must add an external rod brake or a pilot-operated check valve.
