This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X250S, 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 SU80X250S
The AirTAC SU63-100 Standard Cylinder SU80X250S is a double-acting profile-type standard cylinder with a Ø80mm bore and 250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X250S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X250S
The AirTAC SU80X250S is a discontinued double-acting profile-type cylinder with an 80mm bore and 250mm stroke, delivering 2513N of push force at 0.5MPa. AirTAC replaced this end-of-life unit with the SAU80X250S, a direct alternative retaining the exact 3/8 port, M20x1.5 rod thread, and SC-series mounting footprint.
Because the SU80X250S includes a piston magnet (-S), it originally worked with legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to the modern CMSG/DMSG/EMSG sensor family. The extruded aluminum body is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X250S 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 SAU80X250S 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 SU80X250S Is Used
Package Diverting
Pushes heavy cartons off a main transport line using the 2513N thrust at 0.5MPa, with the 250mm stroke clearing guide rails.
Pallet Stopper
Acts as a robust end-stop for inbound pallets, absorbing kinetic energy via the 28mm adjustable air cushions at both ends.
Replacing the Airtac SU63-100 Standard Cylinder SU80X250S with the SAU80X250S
To replace this discontinued SU80X250S, order the SAU80X250S, confirming the 80mm bore, 250mm stroke, 3/8 port, and PT thread. If your machine relied on the -S magnet for positioning, note that the SAU requires CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B. If you need integrated flow control, the SAU line offers a SAUF variant with a built-in 4M solenoid valve the SU lacked. Sizing both ways: dropping to a 63mm bore yields 1559N push at 0.5MPa, while stepping up to 100mm provides 3927N. At 250mm stroke, ensure guide rails carry side loads to prevent rod bending. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X250S
- ✓ 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 SU80X250S FAQ
Yes, the SU80X250S is discontinued. The direct replacement is the AirTAC SAU80X250S. It matches the 80mm bore, 250mm stroke, 2513N push force at 0.5MPa, 3/8 port, and SC-series mounting accessories, fitting the same space.
The SAU80X250S provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a theoretical max of 513kgf at 1.0MPa. Because the original SU80X250S used a magnet (-S) with legacy CS1-B/DS1-B switches, the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
