About the Airtac SC100 Standard Cylinder SC100X303S
The SC100X303S is a double-acting single-rod pneumatic cylinder with a 100 mm bore and 303 mm stroke, factory-equipped with a built-in magnet (-S) so CMSG/DMSG/EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for non-contact position sensing. At 0.5 MPa it pushes with 3927 N and pulls with 3681 N; at the maximum operating pressure of 0.9 MPa the extending thrust reaches 7068 N, placing this model in a high-force class for pressing, clamping, and lifting stations.
This tie-rod cylinder uses a 25 mm diameter piston rod with M20×1.5 male knuckle threads and PT1/2 ports. The 29 mm air cushion at each end is adjustable, letting you dial in end-of-stroke deceleration for smooth, low-impact stopping. The body length A is 188 mm, so the total extended length is approximately 491 mm. Standard TPU/NBR seals give an operating temperature range of -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X303S Is Used
Pallet Stop & Lift Gates
The 3927 N push force at 0.5 MPa easily raises or stops heavy pallets on conveyor lines. The built-in magnet lets you mount CMSG sensors to confirm gate-open and gate-closed positions for interlocked material flow.
Heavy Press & Clamp Fixtures
With 7068 N available at 0.9 MPa, this 100 mm bore cylinder suits weld-clamping jigs and assembly presses. The adjustable air cushion protects tooling by decelerating the 25 mm rod smoothly at each stroke end.
Bag & Bulk Filling Stations
The 303 mm stroke provides the long travel needed to lower a filling head into a bulk container. Sensor feedback from the -S magnet confirms retracted and extended positions, ensuring accurate fill-level control.
Is the Airtac SC100 Standard Cylinder SC100X303S the Right Cylinder?
For applications that need slightly less force, stepping down to the 80 mm bore SC80 series delivers 2513 N push at 0.5 MPa, while moving up to the 125 mm bore SC125 provides 6136 N at the same pressure. At a 303 mm stroke the unsupported rod is long enough that side loads must be managed carefully—fit an external linear guide or switch to a guided cylinder if the load applies any radial force, because a tie-rod cylinder is designed for axial thrust only.
When replacing an existing cylinder, match five points: 100 mm bore, 303 mm stroke, PT1/2 port thread, the built-in magnet (-S) for sensor mounting, and the basic (no-bracket) mounting style. If the original cylinder used a different port thread or lacked a magnet, confirm sensor and fitting compatibility before ordering.
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 SC100X303S FAQ
At 0.5 MPa the cylinder pushes with 3927 N and pulls with 3681 N. At 0.7 MPa the push force rises to 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf. All figures assume clean, filtered air at 40 µm and a standard directional valve circuit.
Yes. The -S suffix in SC100X303S means the piston carries a built-in magnet. AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors clamp directly onto the tie-rod barrel without any additional brackets, giving you non-contact end-of-stroke or mid-stroke position signals.
