This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X275S, 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 SU80X275S
The AirTAC SU63-100 Standard Cylinder SU80X275S is a double-acting profile-type standard cylinder with a Ø80mm bore and 275mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X275S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X275S
The AirTAC SU80X275S is a discontinued double-acting profile cylinder with an 80mm bore and 275mm stroke. Delivering 2513N push force at 0.5MPa, it uses a 3/8" port. AirTAC replaced it with the SAU80X275S direct: identical bore, stroke, force, port and SC-series mounts. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.
The SAU upgrade reuses the same body but adds new features. The -S magnet on this legacy unit worked with CS1-B/DS1-B switches; the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also offers a SAUF built-in-valve variant the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X275S 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 SAU80X275S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×275 | 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 SU80X275S Is Used
Pallet Diversion
Pushes heavy pallets onto secondary lines using 2513N thrust at 0.5MPa, with the 275mm stroke clearing the conveyor frame.
Press Ejection
Ejects formed metal parts from a press bed, where the adjustable 28mm cushions absorb kinetic energy at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X275S with the SAU80X275S
To replace this SU80X275S, order the SAU80X275S. Confirm the 80mm bore, 275mm stroke, 3/8" port, M20x1.5 rod thread and SC-series mounting. The -S magnet means you must change sensors: the old CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG on the SAU. If sizing down, a 63mm bore yields 1559N push at 0.5MPa; sizing up to 100mm gives 3927N. A plain cylinder drifts on air loss—the 28mm cushions only decelerate, so use an external rod lock for held loads. For the 275mm stroke, use a guide to prevent rod bending from side loads. Consider the SAUF if you need a built-in 4M valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X275S
- ✓ 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 SU80X275S FAQ
Yes, the SU80X275S is discontinued. The direct replacement is the SAU80X275S. It shares the same 80mm bore, 275mm stroke, 3/8" port, output force and SC-series mounting. You must swap the old CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAU.
This double-acting cylinder has a 3/8" port. It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N at 0.9MPa, and a maximum theoretical force of 513kgf at 1.0MPa. Operating speed is 30-800mm/s.
