About the Airtac SC100 Standard Cylinder SC100X105STC
The SC100X105STC delivers a substantial 3927 N of push force at 0.5 MPa, making it a robust choice for medium-stroke clamping and pressing tasks. Its 25 mm diameter rod and 29 mm adjustable air cushion provide stable deceleration, while the centre trunnion mount allows the cylinder to pivot during operation.
This model includes a built-in magnet, enabling direct mounting of CMSG/DMSG/EMSG sensors for precise position feedback. The 105 mm stroke keeps the assembly compact, with a total extended length of approximately 293 mm from the 188 mm body, fitting well into pivoting fixtures where space is constrained.

Where the Airtac SC100 Standard Cylinder SC100X105STC Is Used
Welding Fixture Clamping
The 3927 N force securely clamps workpieces in automated welding cells, with the trunnion mount allowing the cylinder to pivot into position.
Part Diverter Gates
Pivoting diverter arms on conveyors benefit from the SC100X105STC's centre trunnion and magnetic sensors to confirm gate open/closed status.
Mould Press Actuation
Provides the push force for core pulls or ejector mechanisms in injection moulding tools, with sensor feedback for cycle safety.
Is the Airtac SC100 Standard Cylinder SC100X105STC the Right Cylinder?
For higher force in the same bore class, step up to an SC125 (6136 N at 0.5 MPa); for a lighter, more compact solution, the SC80 offers 2513 N. The centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC100TC), is ideal for applications requiring the cylinder to swing through an arc. When replacing, match bore, 105 mm stroke, PT port thread, TC mount, and the -S magnet option to ensure sensor compatibility.

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 SC100X105STC FAQ
At 0.7 MPa operating pressure, the SC100 bore produces 5497 N of push force and 3681 N of pull force on the retract stroke.
No. The SC100 is a double-acting cylinder and will drift or drop if pressure is exhausted. To hold a position without live air, you must add a pilot-operated check valve or an external rod brake.
