This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X100STC, 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 SU80X100STC
The AirTAC SU63-100 Standard Cylinder SU80X100STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X100STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X100STC
The AirTAC SU80X100STC is a discontinued double-acting profile-type cylinder with an 80 mm bore and 100 mm stroke. AirTAC replaced this end-of-line unit with the SAU80X100STC, a direct replacement retaining the exact 3/8" port, M20x1.5 rod thread, 513 kgf maximum force, and SC-series TC mounting interface. The extruded aluminum body is shorter and more compact than an ISO 15552 cylinder of the same bore.
This legacy unit features a piston magnet for CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X100STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X100STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×100 | 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 SU80X100STC Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line utilizing the 2513 N thrust at 0.5 MPa without requiring high-pressure regulators.
Press Ejection
Ejects formed metal or plastic parts from a press bed, where the TC mount and 28 mm adjustable cushions absorb end-of-stroke impact.
Replacing the Airtac SU63-100 Standard Cylinder SU80X100STC with the SAU80X100STC
To replace the SU80X100STC, order the SAU80X100STC and verify your 80 mm bore, 100 mm stroke, 3/8" port, and TC mounting accessories. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new SAU cylinder. If you need integrated air control, consider the SAUF valve-integrated variant. Sizing both ways: dropping to a 63 mm bore reduces force to 1559 N at 0.5 MPa, while stepping up to a 100 mm bore increases it to 3927 N. Remember that a plain double-acting cylinder drifts without live air; the 28 mm adjustable cushions only decelerate near stroke end. For suspended loads, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X100STC
- ✓ 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 SU80X100STC FAQ
Yes, the SU80X100STC is discontinued. The direct replacement is the SAU80X100STC, which shares the same 80 mm bore, 100 mm stroke, 3/8" port, 513 kgf max force, and SC-series TC mounting.
At 0.5 MPa it provides 2513 N push and 2268 N pull force, 3518 N push at 0.7 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa. This -S model uses legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
