About the Airtac SC32 Standard Cylinder SC32X250N
The AirTAC SC32X250N is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). Its 12 mm piston rod and 21 mm adjustable air cushion make it a reliable workhorse for light automation tasks requiring a 250 mm linear stroke.
This model is fitted with NBR (nitrile) seals, offering good resilience for general-purpose industrial air within the standard -20 to +70 °C temperature range. The body length A is 140 mm, giving a total extended length of approximately 390 mm, and it breathes through standard PT1/8 ports.

Where the Airtac SC32 Standard Cylinder SC32X250N Is Used
Small Part Sorting
The 250 mm stroke and 12 mm rod are ideal for pushing lightweight components off a conveyor line, with the NBR seals providing consistent performance in standard factory air systems.
Clamping & Holding
Apply a controlled 402 N clamping force at 0.5 MPa for gluing or assembly jigs. The adjustable cushion decelerates the rod quietly at the end of its 250 mm travel.
Test Rig Actuation
Use the SC32X250N in life-cycle test fixtures. Its tie-rod construction is easy to service, and the NBR seals are a cost-effective choice for high-cycle dry-air applications.
Is the Airtac SC32 Standard Cylinder SC32X250N the Right Cylinder?
Choose the SC32 bore for light push/pull tasks up to 402 N at 0.5 MPa. If your load requires more force, step up to the SC40 bore, which provides 628 N at the same pressure. For this 250 mm stroke, the rod is well-supported within standard limits, but avoid direct side loading without an external guide.
To ensure a drop-in replacement, match five key points: 32 mm bore, 250 mm stroke, PT1/8 port thread, NBR seal material, and the basic (no bracket) mounting configuration. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile 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 SC32X250N FAQ
At the standard 0.5 MPa operating pressure, 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.
Yes, the SC32X250N is a direct functional replacement for a standard SC32X250 with TPU seals, provided your operating temperature stays within the -20 to +70 °C range. NBR offers excellent abrasion resistance and is a common upgrade for longevity in dry, filtered air systems.
