About the Airtac SC32 Standard Cylinder SC32X12
The AirTAC SC32X12 is a compact double-acting pneumatic cylinder delivering 402 N of push force at 0.5 MPa, ideal for short-stroke clamping and ejecting tasks. Its 12 mm rod and 21 mm air cushion ensure smooth, controlled motion in tight spaces.
With a body length of just 140 mm plus the 12 mm stroke, this tie-rod cylinder fits where space is limited. The adjustable cushion decelerates the piston quietly, and the PT1/8 port accepts standard pneumatic fittings for straightforward installation.

Where the Airtac SC32 Standard Cylinder SC32X12 Is Used
Short-Stroke Clamping
The 12 mm stroke and 402 N force at 0.5 MPa make it suitable for compact fixture clamping in CNC machining and assembly jigs.
Small Part Ejection
Rapidly ejects lightweight components from conveyor lines or pick-and-place nests with the SC32X12's quick 30-800 mm/s speed range.
Lab Automation Actuation
Provides precise, repeatable linear motion for sample handling and valve actuation in laboratory automation equipment.
Is the Airtac SC32 Standard Cylinder SC32X12 the Right Cylinder?
For applications needing more force, step up to the SC40 bore which provides 628 N push at 0.5 MPa. This 12 mm stroke is well within the 1000 mm maximum standard stroke for the 32 mm bore. To ensure a correct replacement, match five points: bore (32 mm), stroke (12 mm), port thread (PT), mounting accessory (none on this basic model), and magnet option (absent).
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 SC32X12 FAQ
At the standard 0.5 MPa operating pressure, the push force is 402 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 SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It should only replace another AirTAC SC tie-rod cylinder with the same 32 mm bore, 12 mm stroke, and PT port thread.
