This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X350S, 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 SU80X350S
The AirTAC SU63-100 Standard Cylinder SU80X350S is a double-acting profile-type standard cylinder with a Ø80mm bore and 350mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X350S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X350S
The AirTAC SU80X350S is a discontinued double-acting profile-type cylinder with an 80mm bore and 350mm stroke. Delivering 2513N push and 2268N pull at 0.5MPa, it uses a 3/8" port and M20x1.5 rod thread. AirTAC replaced this EOL unit with the SAU80X350S, a direct alternative retaining the exact bore, stroke, force, port and SC-series mounting.
The SAU upgrade keeps the compact extruded aluminium body but switches the -S magnet sensor compatibility from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in 4M valve option. Note that standard cylinders drift without live air; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X350S 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 SAU80X350S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU80X350S Is Used
Pallet Diversion
Pushes heavy pallets laterally across transfer lines using 2513N thrust at 0.5MPa, with the 350mm stroke clearing conveyor frames.
Stack Discharge
Ejects completed goods from vertical storage magazines, requiring external guides to manage the 350mm stroke and prevent rod bending.
Press Ejection
Extracts formed parts from heavy presses, utilising the 28mm adjustable air cushions to decelerate the 80mm piston at stroke ends.
Replacing the Airtac SU63-100 Standard Cylinder SU80X350S with the SAU80X350S
To replace this discontinued SU80X350S, order the SAU80X350S direct equivalent, verifying your 3/8" port, M20x1.5 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 CMSG/DMSG/EMSG sensors. If sizing alternatives, a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. For the 350mm stroke, use external guides to prevent rod bending under side loads. The cushion only decelerates; install a pilot-operated check valve for load holding. Consider the SAUF variant if you need a self-switching integrated valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X350S
- ✓ 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 SU80X350S FAQ
Yes, the SU80X350S is discontinued. The direct replacement is the SAU80X350S, matching the 80mm bore, 350mm stroke, 3/8" port, output force and SC-series mounting.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf maximum at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
