This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X270SCA, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SU63-100 Standard Cylinder SU100X270SCA
The AirTAC SU63-100 Standard Cylinder SU100X270SCA is a double-acting profile-type standard cylinder with a Ø100mm bore and 270mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X270SCA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X270SCA
The AirTAC SU100X270SCA is a discontinued double-acting profile-type cylinder with a 100 mm bore and 270 mm stroke. It delivers 3927 N push force at 0.5 MPa and features an extruded aluminum barrel with adjustable air cushions at both ends. The direct replacement is the SAU100X270SCA, which matches the original 1/2 inch port, M20x1.5 rod thread, and SC-series CA mounting interface.
When upgrading, the SAU100X270SCA body, bore, and force remain identical, but the sensor family changes: this legacy SU model used CS1-B/DS1-B switches, whereas the SAU uses current CMSG/DMSG/EMSG switches. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU never offered.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X270SCA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SU63-100 Standard Cylinder SU100X270SCA Is Used
Heavy Stamp Press Feed
Drives heavy material blanks into a stamping press using the 3927 N push force at 0.5 MPa, relying on the 29 mm adjustable cushion to absorb impact.
Mold Clamping Fixture
Secures heavy injection molds via the CA mounting interface, providing rigid holding while the 1/2 inch port ensures rapid actuation.
Replacing the Airtac SU63-100 Standard Cylinder SU100X270SCA with the SAU100X270SCA
To replace the SU100X270SCA, order the SAU100X270SCA and verify your 100 mm bore, 270 mm stroke, 1/2 inch port, and CA mounting accessory. Because this SKU includes a magnet (-S), you must replace the legacy CS1-B/DS1-B switches with CMSG/DMSG/EMSG sensors. If you need integrated air control, consider the SAUF100 variant which features a built-in valve. Sizing both ways: dropping to an 80 mm bore reduces push force to 2513 N at 0.5 MPa, while staying at 100 mm yields 5497 N at 0.7 MPa. Note that a plain cylinder drifts on air loss—the cushion only decelerates near stroke end—so use an external rod lock for held loads. At 270 mm stroke, ensure adequate guidance to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU100X270SCA
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU63-100 Standard Cylinder SU100X270SCA FAQ
Yes, the SU100X270SCA is discontinued. The direct replacement is the SAU100X270SCA, which maintains the same 100 mm bore, 270 mm stroke, 1/2 inch port, and CA mounting. You simply order the SAU equivalent.
At 0.5 MPa it provides 3927 N push and 3681 N pull force, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this SKU has a magnet, it used CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
