This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X270, 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 SU63X270
The AirTAC SU63-100 Standard Cylinder SU63X270 is a double-acting profile-type standard cylinder with a Ø63mm bore and 270mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X270, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X270
The AirTAC SU63X270 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 270 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X270, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors and a SAUF valve-integrated variant the SU lacked. This SKU has no magnet and cannot accept a switch. The cushion only decelerates; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X270 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X270 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 SU63X270 Is Used
Pallet Stopper
Acts as a pneumatic stop for incoming pallets, absorbing kinetic energy with its 21 mm adjustable air cushions.
Clamp Actuator
Secures 79 kg workpieces during machining, requiring an external check valve to maintain clamp force on air loss.
Replacing the Airtac SU63-100 Standard Cylinder SU63X270 with the SAU63X270
To replace the SU63X270, order the SAU63X270 after confirming your 3/8" port, M16x1.5 rod thread and SC-series mount. This non-magnet SKU cannot take a sensor; if you need position detection, specify an SAU-S model and migrate to CMSG/DMSG/EMSG switches. For load holding, add a pilot-operated check valve, as cushions only decelerate. At 270 mm stroke, guide the load to prevent rod bending. If you need more force, an 80 mm bore offers 2513 N push at 0.5 MPa; if less is acceptable, a 50 mm bore provides 982 N. The SAUF variant adds a built-in 4M valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X270
- ✓ 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 SU63X270 FAQ
Yes, the SU63X270 is discontinued. The direct replacement is the SAU63X270. It matches the 63 mm bore, 270 mm stroke, 1559 N force at 0.5 MPa, 3/8" port and SC-series mounting, so it fits the same application directly.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. It pushes 2182 N at 0.7 MPa, 2805 N at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. The cylinder does not hold load on air loss; the 21 mm cushions only decelerate near stroke end. Use an external rod lock for holding.
