This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X390, 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 SU80X390
The AirTAC SU63-100 Standard Cylinder SU80X390 is a double-acting profile-type standard cylinder with a Ø80mm bore and 390mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X390, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X390
The AirTAC SU80X390 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 390 mm stroke. It delivers 2513 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU80X390, a direct alternative retaining the exact bore, stroke, output force, and SC-series mounting footprint.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in-valve option the SU lacked. Because this specific SKU has no magnet, it cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X390 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 SAU80X390 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 SU80X390 Is Used
Package Diverting
Drives diverter arms on sorting lines, using the 2513 N thrust to push heavy cartons reliably at cycling speeds up to 800 mm/s.
Pallet Stopping
Acts as a robust end-stop for accumulated pallets, absorbing kinetic energy via the 28 mm adjustable cushions without needing live air to hold.
Press Ejection
Ejects formed parts from mid-size presses, where the 390 mm travel clears the tooling area before the next machine cycle begins.
Replacing the Airtac SU63-100 Standard Cylinder SU80X390 with the SAU80X390
To replace the SU80X390, order the SAU80X390 and verify your 80 mm bore, 390 mm stroke, 3/8" port, and M20x1.5 rod thread. If stepping up or down, adjacent bores (63 mm or 100 mm) alter the 0.5 MPa push force (1559 N or 3927 N). This non-magnetic SKU cannot take a switch; if sensing is needed, select an SAU-S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. The 390 mm stroke requires external guides to prevent rod bending under side loads. For load holding on air loss, add an external rod lock, as cushions only decelerate. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X390
- ✓ 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 SU80X390 FAQ
Yes, the SU80X390 is discontinued. The direct replacement is the AirTAC SAU80X390. It matches the 80 mm bore, 390 mm stroke, 3/8" port, 513 kgf max force, and SC-series mounting accessories, so it fits the same application directly.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. This SKU lacks a magnet, so it cannot accept sensors; the SAU-S replacement uses CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B.
