This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X260, 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 SU80X260
The AirTAC Airtac SU63-100 Standard Cylinder SU80X260 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 SAU80X260, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X260
The AirTAC SU80X260 is a discontinued double-acting profile-type cylinder with an 80mm bore and 260mm stroke. Delivering 2513 N push force at 0.5 MPa, it features a 3/8" port and an extruded aluminum body that is more compact than an ISO 15552 cylinder of the same size. AirTAC replaced this legacy unit with the SAU80X260, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
Because this specific SKU lacks a magnet, it cannot accept a sensor. The SAU80X260 upgrade introduces current CMSG/DMSG/EMSG switches for magnetized variants, plus a new SAUF built-in-valve option the SU line never had. Operating pressure is 0.15-1.0 MPa with adjustable cushions at both ends.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X260 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 SAU80X260 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 SU80X260 Is Used
Pallet Diversion
Pushes heavy pallets off a main conveyor line utilizing the 2513 N thrust at 0.5 MPa, with the 260mm stroke clearing the belt width.
Press Ejection
Ejects formed metal or plastic parts from a press bed, relying on adjustable 28mm air cushions to decelerate the 25mm rod smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X260 with the SAU80X260
To replace the discontinued SU80X260, order the SAU80X260 direct equivalent, verifying your 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). This non-magnetized SKU cannot support a sensor; if position detection is needed, specify an SAU80X260S and migrate to CMSG/DMSG/EMSG switches. For loads needing 3518 N at 0.7 MPa, the 80mm bore is ideal, while stepping down to a 63mm bore yields 1559 N. Remember, a standard cylinder drifts without live air—the cushion only decelerates near stroke end—so add an external rod lock or pilot-operated check valve for secure load holding. The SAUF variant integrates a 4M valve if you need self-switching. At 260mm stroke, guide the load to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU80X260
- ✓ 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 SU80X260 FAQ
Yes, the AirTAC SU80X260 is discontinued and end-of-life. The direct replacement is the SAU80X260. It shares the identical 80mm bore, 260mm stroke, 3/8" port, output force, and SC-series mounting, so it fits the same application without mechanical modifications.
The 80mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor; magnetized SAU replacements use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
