About the Airtac SC100 Standard Cylinder SC100X285
The SC100X285 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 285 mm stroke. At 0.5 MPa it generates a push force of 3927 N, stepping up to 7068 N at the maximum operating pressure of 0.9 MPa, placing it firmly in the heavy-push class for pressing, clamping, and lifting tasks.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT1/2 ports. The body length A is 188 mm, giving a total extended length of approximately 473 mm. Its adjustable air cushion (29 mm length) decelerates the piston smoothly at each end of stroke, protecting the end caps during high-cycle operation.

Where the Airtac SC100 Standard Cylinder SC100X285 Is Used
Pallet Stop & Lift
The 3927 N push force at 0.5 MPa reliably raises or stops heavy pallets on conveyor lines, with the 285 mm stroke providing ample lift height for transfer stations.
Heavy-Duty Clamping
Delivers up to 7068 N at 0.9 MPa for pressing bearings, holding large weldments, or clamping thick assemblies in jigs and fixtures.
Material Ejection
The 285 mm stroke ejects large formed parts or scrap from stamping and molding machines, with the adjustable cushion softening the end-of-stroke impact on the tooling.
Is the Airtac SC100 Standard Cylinder SC100X285 the Right Cylinder?
Choose the SC100 when a 3927 N push at 0.5 MPa is needed. If your load requires less force, stepping down to the SC80 bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For higher force, the SC125 delivers 6136 N at the same pressure.
At a 285 mm stroke, side-loading on the 25 mm rod is a key consideration. For applications where the load is not guided externally, consider adding an external guide rail or switching to a guided cylinder to prevent rod bearing wear and bending. When replacing an existing unit, match five points: 100 mm bore, 285 mm stroke, PT1/2 port thread, basic (no mounting accessory), and no magnet.
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 SC100X285 FAQ
At 0.5 MPa the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X285 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a position without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
