This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X320SH, 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 SU80X320SH
The AirTAC Airtac SU63-100 Standard Cylinder SU80X320SH is a double-acting profile-type standard cylinder with a Ø80mm bore and 320mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X320SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X320SH
The AirTAC SU80X320SH is a discontinued double-acting profile cylinder with a high-temperature Viton H seal (0-150 C). Delivering 2513 N push and 2268 N pull at 0.5 MPa, its direct replacement is the SAU80X320SH. The SAU retains the 80 mm bore, 320 mm stroke, 3/8" port, and SC-series mounting, meaning no mechanical redesign is needed.
This profile body is shorter than an ISO 15552 cylinder of the same bore. The -S magnet on this legacy unit worked with CS1-B/DS1-B switches, but the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF built-in 4M valve option the SU lacked.

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 SAU80X320SH 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 SU80X320SH Is Used
Heavy Transfer Divert
Swings a heavy diverter arm on a packaging line; the 320 mm stroke provides the reach needed to span wide belt lanes while the profile body saves space.
Pallet Stop Gate
Acts as a raised stop for incoming pallets, using the 2513 N push force at 0.5 MPa to absorb kinetic impact without bouncing back.
Replacing the Airtac SU63-100 Standard Cylinder SU80X320SH with the SAU80X320SH
To replace this SU80X320SH, order the SAU80X320SH. Verify your 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) stay the same. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. The -H Viton seal handles up to 150 C. For loads needing holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. With the 320 mm stroke, use an external guide to prevent rod bending and side-load wear. If you need less force, step down to a 63 mm bore (1559 N push @0.5 MPa); if you need more, step up to 100 mm (3927 N). The SAUF valve-integrated variant is available if you want to simplify plumbing.
Replacement checklist
- ✓ Same bore / stroke → SAU80X320SH
- ✓ 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 SU80X320SH FAQ
Yes, the SU80X320SH is discontinued. The direct replacement is the SAU80X320SH. It matches the 80 mm bore, 320 mm stroke, 513 kgf max force, 3/8" port, and SC-series mounting. You simply order the SAU equivalent.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf max at 1.0 MPa. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
