This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X110CA, 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 SU63X110CA
The AirTAC Airtac SU63-100 Standard Cylinder SU63X110CA is a double-acting profile-type standard cylinder with a Ø63mm bore and 110mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X110CA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X110CA
The AirTAC SU63X110CA is a discontinued double-acting profile-type cylinder featuring a 63 mm bore and 110 mm stroke. Delivering 1559 N push force at 0.5 MPa, it utilizes an extruded aluminum barrel with adjustable air cushions at both ends, making it more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this end-of-life unit with the SAU63X110CA, a direct replacement retaining the exact same body dimensions, 3/8" port, M16x1.5 rod thread, output force, and SC-series CA mounting interface.
When upgrading to the SAU63X110CA, the bore, stroke, and force remain identical, but the legacy CS1-B/DS1-B sensors are replaced by the modern CMSG/DMSG/EMSG switch family. Because this specific SU63X110CA lacks a magnet, it cannot accept any sensor. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, a self-switching option the SU line never offered.

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 SAU63X110CA 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 SU63X110CA Is Used
Clamping Fixtures
Secures heavy machined parts during milling with 1559 N of clamping force at 0.5 MPa, utilizing the 110 mm stroke to clear the workpiece for robotic loading.
Package Diverting
Actuates routing gates on packaging lines where the compact extruded profile saves space while providing reliable 1402 N pull force to redirect heavy cartons.
Replacing the Airtac SU63-100 Standard Cylinder SU63X110CA with the SAU63X110CA
To replace the discontinued SU63X110CA, order the SAU63X110CA, confirming the 63 mm bore, 110 mm stroke, 3/8" port, and CA mounting accessory are retained for a direct fit. Since this SKU lacks a magnet (-S), it cannot support sensing; if you need position detection, specify an SAU63X110CAS and use the current CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B. For sizing, the 63 mm bore yields 1559 N push and 1402 N pull at 0.5 MPa; if you need less force, step down to a 50 mm bore (982 N push), or step up to an 80 mm bore (2513 N push) for heavier loads. Note that a plain cylinder drifts on air loss—the cushion only decelerates near stroke end—so use an external rod lock or pilot-operated check valve for load holding. You can also explore the SAUF variant if you need a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X110CA
- ✓ 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 SU63X110CA FAQ
Yes, the AirTAC SU63X110CA is discontinued. The direct replacement is the SAU63X110CA. It shares the identical 63 mm bore, 110 mm stroke, 3/8" port, M16x1.5 rod thread, force output, and SC-series CA mounting, so it fits the same application without modifications.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Because this specific SU63X110CA lacks a magnet, it cannot accept a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches, but only if you order the -S magnet version.
