This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X80S, 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 SU63X80S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X80S is a double-acting profile-type standard cylinder with a Ø63mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X80S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X80S
The AirTAC SU63X80S is a discontinued double-acting profile cylinder with an 80 mm stroke and a 63 mm bore. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X80S, a direct upgrade retaining the exact bore, stroke, output force, port size and SC-series mounting footprint.
The SAU replacement modernizes the sensor groove to accept current CMSG, DMSG and EMSG switches, whereas this legacy SU-S model used older CS1-B or DS1-B reed switches. Furthermore, the SAU line introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X80S 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 SAU63X80S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×80 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU63X80S Is Used
Package Diversion
Drives sorting gates and pushers on packaging lines, where the compact profile body saves space while delivering 1559 N of thrust.
Vertical Lift Stops
Functions as a pneumatic stop or low-height lift gate for loads up to 79 kg, benefiting from the 21 mm adjustable cushions at both ends.
Replacing the Airtac SU63-100 Standard Cylinder SU63X80S with the SAU63X80S
To replace this SU63X80S, order the SAU63X80S by confirming the 63 mm bore, 80 mm stroke, 3/8" port, M16x1.5 rod thread and default PT threads. Because this SKU includes the -S magnet, you must switch your legacy CS1-B or DS1-B switches to the modern CMSG, DMSG or EMSG family. If your application requires load holding on air loss, note that the adjustable cushion only decelerates the piston and does not lock it; you must add an external rod lock or pilot-operated check valve. For higher force demands, the neighboring 80 mm bore provides 2513 N push at 0.5 MPa, while dropping to the 50 mm bore yields 982 N. You can also explore the SAUF variant if you need a self-switching cylinder with an integrated valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X80S
- ✓ 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 SU63X80S FAQ
Yes, the AirTAC SU63X80S is discontinued and end-of-life. The direct replacement is the SAU63X80S. It shares the identical 63 mm bore, 80 mm stroke, 1559 N force, 3/8" port and SC-series mounting, so it fits the same application without mechanical modifications.
The cylinder provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. Because your SU63X80S has a magnet, the SAU replacement requires upgrading from the legacy CS1-B or DS1-B switches to the current CMSG, DMSG or EMSG sensor family.
