About the Airtac SC100 Standard Cylinder SC100X450STC
The AirTAC SC100X450STC is a double-acting single-rod pneumatic cylinder delivering a robust 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 450 mm stroke, it handles mid-to-heavy linear actuation tasks where consistent thrust is critical.
This model features a built-in magnet for mounting CMSG/DMSG/EMSG sensors directly on the barrel, and comes supplied with the TC centre trunnion pivot (F-SC100TC) plus the TCM1 bracket. The trunnion mount allows the cylinder to swing during operation, ideal for pivoting loads. The 25 mm diameter rod and PT1/2 ports ensure solid power transmission.

Where the Airtac SC100 Standard Cylinder SC100X450STC Is Used
Conveyor Diverters
The 450 mm stroke and 3927 N push force efficiently actuates heavy-duty diverters or gates on wide conveyor lines, routing packages or pallets.
Press & Clamp Fixtures
Supplies up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during welding, assembly, or machining operations.
Pivoting Machinery Links
The integrated TC centre trunnion mount allows the cylinder body to pivot, making it suitable for articulated machine arms or oscillating linkages.
Is the Airtac SC100 Standard Cylinder SC100X450STC the Right Cylinder?
For a step up in force, the SC125 bore offers 6136 N push at 0.5 MPa. If a lower force and smaller footprint are acceptable, the SC80 provides 2513 N. At a 450 mm stroke, ensure the 25 mm rod is adequately supported if side loads are present; long unsupported rods can bend. For side-loaded applications, consider pairing with an external linear guide. Replacement must match bore, stroke, PT port thread, TC trunnion mount, and the -S magnet option.
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 SC100X450STC FAQ
At 0.5 MPa it delivers 3927 N pushing and 3681 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. As a standard double-acting cylinder, it does not lock or hold position if air pressure is lost or the valve is centered. For load holding, an external pilot-operated check valve or mechanical rod lock is required.
