This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X30STC, 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 SU80X30STC
The AirTAC SU63-100 Standard Cylinder SU80X30STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 30mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X30STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X30STC
The AirTAC SU80X30STC is a discontinued double-acting profile-type cylinder featuring an 80 mm bore, a 30 mm stroke, a 3/8" port, and an integrated TC mount. Delivering 2513 N of push force at 0.5 MPa, it is replaced directly by the SAU80X30STC. This direct successor matches the original bore, stroke, output force, port size, and SC-series mounting interface exactly, dropping right into your existing machinery.
Because this SKU includes a piston magnet (-S), it originally used legacy CS1-B/DS1-B switches; upgrading to the SAU80X30STC means migrating to the current CMSG/DMSG/EMSG sensor family. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore. The SAU line also introduces the SAUF built-in 4M solenoid valve option, which the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X30STC 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 SAU80X30STC 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 SU80X30STC Is Used
Short-Stroke Clamping
Ideal for high-force 2513 N clamping tasks in machining fixtures where a compact 30 mm stroke securely holds heavy cast components.
Transfer Line Diverter
Uses the TC mount to pivot a diverter arm on a packaging conveyor, rapidly sorting goods with a fast 30 mm stroke action.
Pallet Stopper Gate
Functions as a heavy-duty pneumatic stop in automated warehouses, raising a 25 mm rod barrier to halt pallets on a roller deck.
Replacing the Airtac SU63-100 Standard Cylinder SU80X30STC with the SAU80X30STC
To replace the discontinued SU80X30STC, order the SAU80X30STC with the exact same 80 mm bore, 30 mm stroke, M20x1.5 rod thread, and 3/8" port. Confirm your default PT thread and the TC mounting interface, which is an SC-series accessory. If sizing alternatives, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. Remember that a standard cylinder does not hold a load without live air; the adjustable 28 mm cushions only decelerate the piston near stroke end. For load holding on air loss, install an external rod lock or pilot-operated check valve. The -S magnet on this model means you must switch from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the new SAU. If self-switching is needed, explore the SAUF variant with its integrated valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X30STC
- ✓ 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 SU80X30STC FAQ
Yes, the AirTAC SU80X30STC is discontinued and end-of-life. The direct replacement is the SAU80X30STC. It shares the identical 80 mm bore, 30 mm stroke, 3/8" port, 513 kgf max force, and TC mounting interface, so it fits the same application directly.
At 0.5 MPa it pushes 2513 N and pulls 2268 N; at 0.7 MPa it pushes 3518 N, with a theoretical max of 513 kgf at 1.0 MPa. Because this model has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU80X30STC replacement requires upgrading to CMSG/DMSG/EMSG sensors.
