About the Airtac SC100 Standard Cylinder SC100X650STC
The AirTAC SC100X650STC is a double-acting single-rod pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and 650 mm stroke, this model is built for demanding linear applications requiring substantial force over a mid-range travel distance.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) mount, supplied with the TCM1 bracket for pivoting motion. The 25 mm diameter rod, PT1/2 port threads, and 29 mm adjustable air cushion ensure robust, controlled operation. The total extended body length is approximately 838 mm.

Where the Airtac SC100 Standard Cylinder SC100X650STC Is Used
Material Handling Pusher
Provides the high force needed to divert heavy packages or pallets on conveyor lines, with the trunnion mount allowing the cylinder to pivot as it extends and retracts.
Heavy-Duty Clamping
Delivers up to 7068 N of clamping force for holding large workpieces in CNC machining centres or welding fixtures, with sensor confirmation of the clamped state.
Process Valve Actuation
Operates large quarter-turn valves or dampers in processing plants, where the centre trunnion mount accommodates the arc motion of the valve linkage.
Is the Airtac SC100 Standard Cylinder SC100X650STC the Right Cylinder?
When selecting a cylinder for a 650 mm stroke, ensure the 25 mm rod is adequately supported against side loads, especially in horizontal or unsupported orientations; consider external guides or a guided cylinder for long-stroke applications. For higher force requirements, stepping up to the SC125 bore provides 6136 N at 0.5 MPa, while the SC80 offers a more compact alternative at 2513 N.
To ensure a correct replacement, match five key points: 100 mm bore, 650 mm stroke, PT1/2 port thread, the TC centre trunnion mounting accessory (F-SC100TC), and the built-in magnet for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with those standards.
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 SC100X650STC FAQ
At the standard 0.5 MPa operating pressure, the 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.
No, the SC100X650STC is a double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centred. The piston will drift or the load may drop. For load holding, an external rod lock, brake, or pilot-operated check valve is required.
