This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X275S, 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 SU63X275S
The AirTAC SU63-100 Standard Cylinder SU63X275S is a double-acting profile-type standard cylinder with a Ø63mm bore and 275mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X275S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X275S
The AirTAC SU63X275S is a discontinued double-acting profile cylinder with a 63 mm bore and 275 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X275S, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
This compact extruded-aluminium body is shorter than a standard ISO 15552 unit of the same bore. The built-in magnet (-S) originally paired with legacy CS1-B/DS1-B switches, but the SAU replacement now uses current CMSG/DMSG/EMSG sensors. Note that the SAU family also offers a SAUF variant with a built-in 4M solenoid valve, an option the SU line never had.

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 SAU63X275S 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 SU63X275S Is Used
Carton Diverting
Uses the 1559 N push force at 0.5 MPa to deflect heavy packaging along a sorting line, fitting neatly into existing SC-series bracketry.
Replacing the Airtac SU63-100 Standard Cylinder SU63X275S with the SAU63X275S
To replace this discontinued SU63X275S, order the SAU63X275S direct equivalent, verifying the 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) match your existing fixture. Because this 275 mm stroke exceeds 300 mm is not the case here, but always ensure adequate guide support to prevent rod bending under side loads. If sizing alternatives, neighbouring bores (50 mm or 80 mm) offer 982 N or 2513 N push at 0.5 MPa respectively. The -S magnet means you must upgrade switches from CS1-B/DS1-B to CMSG/DMSG/EMSG. Remember, the air cushion only decelerates; it does not hold the load on air loss, so add an external rod lock or pilot-operated check valve if drift is unacceptable. For self-switching needs, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU63X275S
- ✓ 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 SU63X275S FAQ
Yes, the SU63X275S is discontinued. The direct replacement is the AirTAC SAU63X275S. It shares the identical 63 mm bore, 275 mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the same application without mechanical modifications.
At 0.5 MPa it provides 1559 N push and 1402 N pull force, increasing to 2182 N at 0.7 MPa, with a theoretical maximum of 318 kgf at 1.0 MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must switch to the current CMSG/DMSG/EMSG sensor family.
