This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X365, 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 SU80X365
The AirTAC Airtac SU63-100 Standard Cylinder SU80X365 is a double-acting profile-type standard cylinder with a Ø80mm bore and 365mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X365, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X365
The AirTAC SU80X365 is a discontinued double-acting profile-type cylinder with an 80mm bore and 365mm stroke. Built with an extruded aluminum barrel, it delivers 2513 N push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU80X365, a direct replacement retaining the exact body profile, stroke, force, 3/8" port, and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors (the SU used legacy CS1-B/DS1-B switches) and adds an optional SAUF variant with a built-in 4M solenoid valve. Note this SKU lacks a magnet, so it cannot accept sensing switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X365 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 SAU80X365 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 SU80X365 Is Used
Pallet Diversion
Pushes heavy pallets off a main conveyor line using 2513 N of thrust at 0.5 MPa, with the 365mm stroke clearing the belt width completely.
Stamping Ejector
Ejects formed metal parts from a press die, utilizing the adjustable 28mm air cushions at both ends to decelerate the 25mm rod smoothly at stroke limits.
Replacing the Airtac SU63-100 Standard Cylinder SU80X365 with the SAU80X365
To replace this SU80X365, order the SAU80X365 direct equivalent. Confirm the 80mm bore, 365mm stroke, 3/8" port (default PT thread), M20x1.5 rod thread, and SC-series mounting. Because this is a non-magnet SKU, it cannot hold a sensor; if detection is needed, specify an SAU-S model and migrate to CMSG/DMSG/EMSG switches. For load holding, note that a standard cylinder drifts on air loss—the cushions only decelerate—so add an external rod lock or pilot-operated check valve. With a 365mm stroke, use external guides to prevent rod bending under side loads. Neighbouring bores: a 63mm bore yields 1559 N push at 0.5 MPa, while a 100mm bore yields 3927 N.
Replacement checklist
- ✓ Same bore / stroke → SAU80X365
- ✓ 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 SU80X365 FAQ
Yes, the AirTAC SU80X365 is discontinued. The direct replacement is the SAU80X365. It shares the identical 80mm bore, 365mm stroke, 3/8" port, output force, and SC-series mounting, so it drops straight into the same application.
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 specific SKU has no magnet and cannot take sensors. The SAU replacement uses CMSG/DMSG/EMSG switches on its -S variants.
