About the Airtac SC100 Standard Cylinder SC100X250
The SC100X250 is a double-acting pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa. With a 250 mm stroke, this model is built on a robust 25 mm diameter piston rod and features a 188 mm body length, making it a compact yet powerful actuator for medium-to-heavy linear motion tasks.
This genuine AirTAC SC series cylinder uses a durable tie-rod construction with PT1/2 ports and an adjustable air cushion to decelerate the piston smoothly. It operates on filtered air within a standard temperature range of -20 to +70 °C, providing reliable, high-force performance for demanding industrial applications.

Where the Airtac SC100 Standard Cylinder SC100X250 Is Used
Pallet Stop and Transfer
Provides the high force needed to reliably stop and lift heavy pallets on conveyor lines, using the 3927 N push at 0.5 MPa to manage substantial inertial loads.
Heavy-Duty Clamping
Delivers a secure, controlled clamping force for large workpieces in machining or welding fixtures, with the adjustable cushion preventing impact damage to the fixture.
Bin Tipper Actuation
Powers the lifting mechanism on industrial bin tippers, handling the high thrust requirements to tilt heavy containers of bulk material safely and efficiently.
Is the Airtac SC100 Standard Cylinder SC100X250 the Right Cylinder?
Select the SC100X250 when your application requires a force class around 4000 N at standard plant pressure. If your load is lighter, stepping down to an 80 mm bore reduces the push force to 2513 N at 0.5 MPa, potentially saving energy and space. For a 250 mm stroke, ensure the load is guided externally if significant side forces are present, as the 25 mm rod can be subject to bending moments.
For a direct replacement, match five key specifications: a 100 mm bore, 250 mm stroke, PT1/2 port thread, the specific mounting accessory (this is a basic body model), and the presence or absence of a magnet. This cylinder is not dimensionally interchangeable with ISO 15552 profiles, so only an identical AirTAC SC tie-rod unit will be a guaranteed drop-in fit.
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 SC100 Standard Cylinder SC100X250 FAQ
At 0.5 MPa, the theoretical push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X250 is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the end of its stroke. To hold a load safely without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
