About the Airtac SC100 Standard Cylinder SC100X420STC
The SC100X420STC is a double-acting tie-rod 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, 25 mm piston rod, and a 420 mm stroke, it handles mid-range linear moves where a compact body length (188 mm base plus stroke) is required.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and the TC centre trunnion mount (supplied with TCM1 bracket, part F-SC100TC) for pivoting applications. The adjustable pneumatic cushion (29 mm) decelerates the piston smoothly, and the standard PT1/2 ports ensure straightforward pneumatic connections.

Where the Airtac SC100 Standard Cylinder SC100X420STC Is Used
Conveyor Diverters
The 3927 N push force at 0.5 MPa and centre trunnion mount allow the cylinder to pivot and divert medium-weight packages or pallets on conveyor lines with sensor-confirmed position feedback.
Clamping & Fixturing
Delivers up to 7068 N of clamping force at 0.9 MPa for holding workpieces in CNC machining centres or welding jigs, with magnetic sensors verifying clamp/unclamp status.
Press & Assembly Tools
Ideal for light press-fit or riveting operations requiring a 420 mm stroke. The adjustable cushion protects tooling at end-of-stroke, and the trunnion mount handles the slight arc of a toggle mechanism.
Is the Airtac SC100 Standard Cylinder SC100X420STC the Right Cylinder?
Choose the SC100 when your application needs around 3927 N at 0.5 MPa. If you can accept slightly lower force in a smaller footprint, the SC80 delivers 2513 N; for heavier loads, the SC125 steps up to 6136 N. The 420 mm stroke is within the 1500 mm maximum standard stroke for this bore.
At 420 mm, the rod is extended significantly. Ensure side loads are minimal or use an external guide to protect the rod bearing from bending moments. For replacement, match bore (100 mm), stroke (420 mm), PT1/2 port thread, TC centre trunnion mount, and the magnet option (-S) to guarantee a drop-in fit for another AirTAC SC tie-rod 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 SC100X420STC 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. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X420STC is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centred. The adjustable air cushion only decelerates the piston at the end of stroke; it is not a locking or holding brake. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
