About the Airtac SC100 Standard Cylinder SC100X400STC
The SC100X400STC is a double-acting pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at the 0.9 MPa maximum operating pressure). Its 400 mm stroke is well within the 1500 mm maximum standard stroke for the 100 mm bore, making it a readily available configuration for medium-travel linear actuation.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC), supplied with the TCM1 bracket (F-SC100TC), allowing the cylinder to pivot during operation. The 25 mm diameter piston rod and 29 mm adjustable air cushion provide robust guidance and smooth end-of-stroke deceleration.

Where the Airtac SC100 Standard Cylinder SC100X400STC Is Used
Material Handling Gates
The 400 mm stroke and high force are ideal for diverting heavy packages or pallets on conveyor lines, with the trunnion mount allowing the cylinder body to swing as the gate actuates.
Heavy-Duty Clamping
Delivers up to 7068 N of clamping force at 0.9 MPa for securing large weldments or engine blocks in machining fixtures, with magnetic sensors confirming jaw position.
Agricultural Equipment Actuation
Powers the pivot of a large chute or hopper door on a combine harvester or spreader, where the centre trunnion mount accommodates the arcing motion of the mechanism.
Is the Airtac SC100 Standard Cylinder SC100X400STC the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 80 mm bore (2513 N at 0.5 MPa). If your load demands more power, the 125 mm bore provides 6136 N at the same pressure. This 400 mm stroke model requires careful management of side loads; the 25 mm rod is strong, but for unsupported or off-centre loads, use an external guide rail or a guided cylinder to prevent rod bending and premature bearing wear.
To ensure a correct replacement, match five key points: 100 mm bore, 400 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This specific configuration ensures a drop-in fit for an existing AirTAC SC tie-rod cylinder.

- ✓ 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 SC100X400STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 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 SC100X400STC is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston can drift or drop. For load holding, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
