About the Airtac SC100 Standard Cylinder SC100X950STC
The SC100X950STC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa operating pressure. With a 100 mm bore and a 25 mm diameter piston rod, this tie-rod cylinder is built for demanding linear actuation tasks where substantial force and a long working stroke are required.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel, plus a centre trunnion mount (TC suffix) supplied with the TCM1 bracket (F-SC100TC). The adjustable air cushion (29 mm) decelerates the piston smoothly at both ends, protecting the end caps during high-speed operation within the 30-800 mm/s speed range.

Where the Airtac SC100 Standard Cylinder SC100X950STC Is Used
Pallet Transfer Systems
The 950 mm stroke and 3927 N push force move heavy pallets across roller conveyors, with the centre trunnion mount allowing the cylinder to pivot as the transfer mechanism cycles.
Automotive Welding Fixtures
Clamping large weldments requires consistent force and long reach. The built-in magnet enables sensor feedback to confirm full clamp engagement before the welding cycle starts.
Dock Leveler Actuation
Raising and lowering heavy dock plates benefits from the 7068 N maximum thrust at 0.9 MPa. The trunnion mount handles the angular movement as the leveler articulates.
Is the Airtac SC100 Standard Cylinder SC100X950STC the Right Cylinder?
Select the SC100 bore when your application needs roughly 4000 N of force at standard shop air; if you can work with about 2500 N, stepping down to an 80 mm bore (2513 N at 0.5 MPa) saves space and air consumption. For strokes approaching 950 mm, always check side-load conditions—a long unsupported 25 mm rod can bend under off-axis loads. Use an external linear guide or a guided cylinder if the load is not perfectly aligned.
To replace an existing cylinder, match five points: 100 mm bore, 950 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the -S magnet for sensor compatibility. This SC series is a tie-rod design, shorter than an ISO 15552 cylinder, so dimensional interchangeability is limited to other AirTAC SC100 tie-rod units.
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 SC100X950STC FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N. At 0.7 MPa, push is 5497 N. The maximum operating push force at 0.9 MPa is 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf (7850 N).
No. The SC100 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift or drop. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
