This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X260S, 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 SU80X260S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X260S is a double-acting profile-type standard cylinder with a Ø80mm bore and 260mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X260S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X260S
The AirTAC SU80X260S is a discontinued double-acting profile-type cylinder with an 80 mm bore and 260 mm stroke. It delivers a push force of 2513 N and pull of 2268 N at 0.5 MPa. AirTAC replaced this end-of-line unit with the SAU80X260S, a direct alternative retaining the exact 3/8" port, M20x1.5 rod thread, output force and SC-series mounting.
The extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore. Note the -S magnet on this legacy unit required CS1-B/DS1-B switches, whereas the SAU replacement utilises current CMSG/DMSG/EMSG sensors and introduces a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X260S 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 SAU80X260S 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 SU80X260S Is Used
Package Diverting
Drives diverter arms on high-throughput packaging lines, utilising the 2513 N push force to redirect heavy cartons reliably at speed.
Pallet Stopping
Acts as a robust end-stop for accumulated pallets on roller conveyors, absorbing kinetic energy via the 28 mm adjustable air cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU80X260S with the SAU80X260S
To replace this discontinued SU80X260S, order the SAU80X260S direct equivalent, verifying your 3/8" port, M20x1.5 rod thread and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the CMSG/DMSG/EMSG family. If your application needs self-switching, the SAU line offers a SAUF variant with a built-in 4M solenoid valve the SU lacked. For loads needing static holding on air loss, fit an external rod lock or pilot-operated check valve, as the adjustable 28 mm cushions only decelerate. When sizing both ways, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. At 260 mm stroke, ensure guide rails carry side loads to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU80X260S
- ✓ 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 SU80X260S FAQ
Yes, the SU80X260S is end-of-life. The direct replacement is the AirTAC SAU80X260S. It matches the 80 mm bore, 260 mm stroke, 2513 N force, 3/8" port and SC-series mounting. You simply order the SAU equivalent.
At 0.5 MPa it pushes 2513 N and pulls 2268 N; at 0.7 MPa it pushes 3518 N, with a theoretical max of 513 kgf at 1.0 MPa. This -S model has a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
