This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X30, 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 SU80X30
The AirTAC Airtac SU63-100 Standard Cylinder SU80X30 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 SAU80X30, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X30
The AirTAC SU80X30 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 30 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU80X30, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting footprint.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent of the same bore. Because this specific SKU lacks a magnet, it cannot accept position sensors. The SAU upgrade also introduces the SAUF valve-integrated variant the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X30 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 SAU80X30 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 SU80X30 Is Used
Short-Stroke Clamping
Ideal for high-force 2513 N parts clamping in machining fixtures where a compact 30 mm stroke securely holds heavy workpieces without protruding into the work zone.
Heavy Diverting
Provides robust actuation for diverting heavier product loads on conveyor lines, using the short stroke to push items cleanly into packing lanes at up to 800 mm/s.
Press Ejection
Serves as a powerful ejection cylinder in automated press operations, using the 80 mm bore thrust to knock out dense stamped parts rapidly from tight tooling.
Replacing the Airtac SU63-100 Standard Cylinder SU80X30 with the SAU80X30
To replace the SU80X30, order the SAU80X30. Confirm your 3/8" port, M20x1.5 rod thread, and SC-series mounting accessories (LB/FA/FB/CA/CB) all carry over directly. Since this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B switches; if you need sensing on the new SAU, you must migrate to the current CMSG/DMSG/EMSG sensor family. If your application needs self-switching, explore the SAUF variant with its built-in 4M solenoid valve. For force context, dropping to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to 100 mm provides 3927 N. Remember, a standard cylinder drifts without live air—the 28 mm cushions only decelerate at end-of-stroke, so fit an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X30
- ✓ 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 SU80X30 FAQ
Yes, the SU80X30 is discontinued. The direct replacement is the AirTAC SAU80X30. It shares the identical 80 mm bore, 30 mm stroke, 2513 N force at 0.5 MPa, 3/8" port, and SC-series mounting hardware, so it bolts right in without mechanical modifications.
The 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept position switches; the SAU replacement supports modern CMSG/DMSG/EMSG sensors if you order the -S version.
