This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X280S, 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 SU80X280S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X280S is a double-acting profile-type standard cylinder with a Ø80mm bore and 280mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X280S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X280S
The AirTAC SU80X280S is a discontinued double-acting profile cylinder featuring an 80mm bore and 280mm stroke. It delivers 2513N push force at 0.5MPa with a 3/8" port. AirTAC replaced this legacy unit with the SAU80X280S, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting accessories.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of the older CS1-B/DS1-B switches fitted to this -S SKU, and introduces the SAUF built-in-valve variant the SU line lacked. Note that air cushions only decelerate; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X280S 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 SAU80X280S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU80X280S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using 2513N thrust at 0.5MPa, with the 280mm stroke clearing the belt frame.
Press Ejection
Ejects formed metal parts from a press bed, relying on the 28mm adjustable air cushions to decelerate the 25mm rod smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X280S with the SAU80X280S
To replace this SU80X280S, order the SAU80X280S direct equivalent, verifying your 3/8" port, M20x1.5 rod thread and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU has the -S magnet, you must switch from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. For loads requiring holding without live air, add a pilot-operated check valve or external rod lock, as cushions only decelerate. At 280mm stroke, guide the load to prevent rod bending and side-load wear. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore yields 3927N. The SAUF variant integrates a 4M solenoid valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU80X280S
- ✓ 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 SU80X280S FAQ
Yes, the SU80X280S is discontinued. The direct replacement is the AirTAC SAU80X280S. It shares the same 80mm bore, 280mm stroke, 2513N force, 3/8" port and SC-series mounting, so it fits the same application directly.
The cylinder provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a maximum theoretical force of 513kgf at 1.0MPa. Because your SU has the -S magnet, the SAU replacement requires upgrading from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family.
