This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X490S, 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 SU80X490S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X490S is a double-acting profile-type standard cylinder with a Ø80mm bore and 490mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X490S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X490S
The AirTAC SU80X490S is a discontinued double-acting profile-type cylinder with an 80mm bore and 490mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, making it a robust choice for heavy loads. The direct replacement is the SAU80X490S, matching the bore, stroke, 3/8" port, and SC-series mounting.
Upgrading to the SAU keeps the compact extruded aluminum body but changes the sensor family. This SU-S magnet variant used legacy CS1-B/DS1-B switches, whereas the SAU replacement requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked. Remember, a plain cylinder drifts on air loss; the adjustable 28mm cushions only decelerate near stroke ends, so fit an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X490S 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 SAU80X490S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU80X490S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×490 | 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 SU80X490S Is Used
Heavy Package Diversion
Handles robust diverting arms on high-throughput packaging lines, using the 2513N push force at 0.5MPa to reliably pivot heavy palletized goods without hesitation.
Press Ejection System
Ejects dense molded parts from hydraulic presses, leveraging the 490mm stroke to clear the tooling area completely while absorbing end-of-stroke impact via adjustable cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU80X490S with the SAU80X490S
To replace this discontinued SU80X490S, order the SAU80X490S direct equivalent. Confirm the 80mm bore, 490mm stroke, 3/8" port (default PT thread), M20x1.5 rod thread, and SC-series mounting hardware. Because this SKU includes the -S magnet, you must switch from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. If you need self-switching action, explore the SAUF valve-integrated option. For sizing, a neighboring 63mm bore offers 1559N push at 0.5MPa, while a 100mm bore provides 3927N. With a 490mm stroke, prevent rod bending by guiding the load externally to avoid side-load stress. For load holding on air loss, add a pilot-operated check valve or external rod lock, as the cushion only decelerates.
Replacement checklist
- ✓ Same bore / stroke → SAU80X490S
- ✓ 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 SU80X490S FAQ
Yes, the AirTAC SU80X490S is discontinued. The direct replacement is the SAU80X490S. It provides identical 80mm bore, 490mm stroke, output force, 3/8" port, and SC-series mounting compatibility. You can swap it directly without modifying your machine.
The 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a theoretical max of 513kgf at 1.0MPa. Because your old SU-S model used CS1-B/DS1-B switches, upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors.
