About the Airtac SC32 Standard Cylinder SC32X125
The SC32X125 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 max operating pressure). Its 12 mm diameter piston rod and 21 mm adjustable air cushion make it well-suited for light-duty clamping, sorting, and ejecting tasks where a 125 mm stroke is required.
With a body length A of just 140 mm, this genuine AirTAC actuator fits into tight machine envelopes. The PT1/8 ports and M10x1.25 rod thread are standard across the SC32 family, simplifying spare-part management.

Where the Airtac SC32 Standard Cylinder SC32X125 Is Used
Component Ejection
The 125 mm stroke and 402 N push force reliably eject small plastic or metal parts from injection-molding or stamping dies.
Diverter Gates
Actuates lightweight diverter flaps on conveyor lines, sorting packages or products with a clean 125 mm linear motion.
Clamping Fixtures
Provides consistent clamping force for woodworking or light assembly jigs, with adjustable cushioning to reduce impact noise.
Is the Airtac SC32 Standard Cylinder SC32X125 the Right Cylinder?
Choose the SC32X125 when your application needs a compact pneumatic cylinder with a force around 400 N at standard shop air. If you need more push force, stepping up to the SC40 bore provides 628 N at the same 0.5 MPa pressure. For strokes of 300 mm or longer on this 12 mm rod, be cautious of side loads—consider an external guide rail or a guided cylinder to prevent rod bending.
To ensure a drop-in replacement, match five key points: 32 mm bore, 125 mm stroke, PT port thread, basic (no bracket) mounting, and confirm the magnet option (this model has no built-in magnet). This SC cylinder is a tie-rod design, not an ISO 15552 profile, so verify body length A (140 mm) against your existing unit.
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 SC32X125 FAQ
At 0.7 MPa operating pressure, the SC32X125 produces a theoretical push force of 563 N. The maximum push force at 0.9 MPa is 724 N.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder. It is only dimensionally interchangeable with another AirTAC SC32 tie-rod cylinder matching the 125 mm stroke, PT ports, and basic mounting.
