About the Airtac SC100 Standard Cylinder SC100X310STC
The SC100X310STC delivers 3927 N of push force at 0.5 MPa and reaches 7068 N at the maximum operating pressure of 0.9 MPa, placing it firmly in the heavy-duty automation class. This double-acting tie-rod cylinder features a 310 mm stroke, a 25 mm diameter piston rod, and a 29 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly.
Supplied as a genuine AirTAC SC series unit, this model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and the centre trunnion (TC) mounting with the TCM1 bracket, allowing the cylinder to pivot under load. The total extended body length is approximately 498 mm, making it a compact yet powerful solution for swinging or articulating movements.

Where the Airtac SC100 Standard Cylinder SC100X310STC Is Used
Pallet Transfer & Lift
The 310 mm stroke and 3927 N push force at 0.5 MPa reliably transfer heavy pallets between conveyor lines or raise lift tables in packaging and logistics centres.
Welding Fixture Clamping
With a centre trunnion mount for pivoting and magnetic sensors for position feedback, this cylinder actuates heavy-duty clamps on automotive welding jigs with precise sequence control.
Material Bending & Forming
Generating up to 7068 N at 0.9 MPa, the SC100X310STC powers press arms and bending brakes in light metal forming, where the adjustable cushion protects tooling at stroke end.
Is the Airtac SC100 Standard Cylinder SC100X310STC the Right Cylinder?
For applications requiring less force, stepping down to an 80 mm bore provides 2513 N at 0.5 MPa, while moving up to a 125 mm bore offers 6136 N. This 310 mm stroke model uses a centre trunnion mount (F-SC100TC) ideal for pivoting applications; ensure the trunnion is aligned precisely to avoid binding. The built-in magnet enables easy end-of-stroke sensing without additional brackets.
When replacing an existing cylinder, match five points: 100 mm bore, 310 mm stroke, PT port thread, centre trunnion (TC) mounting, and the integrated magnet (-S). For strokes over 300 mm, always assess side-loading on the 25 mm rod—if lateral forces are present, use an external guide rail or a guided cylinder to prevent rod bearing wear and bending.
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 SC100X310STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder pushes with 3927 N and pulls with 3681 N. At 0.7 MPa, push force increases to 5497 N, and at the maximum operating pressure of 0.9 MPa, it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No, the SC100X310STC is a double-acting cylinder and will not hold position if pressure is exhausted or the directional valve is centred. The adjustable air cushion only decelerates the piston at stroke end to reduce impact. For load holding without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
