This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X350S, 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 SU63X350S
The AirTAC SU63-100 Standard Cylinder SU63X350S is a double-acting profile-type standard cylinder with a Ø63mm bore and 350mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X350S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X350S
The AirTAC SU63X350S is a discontinued double-acting profile-type cylinder with a 63mm bore and 350mm stroke. Delivering 1559N push force at 0.5MPa, it uses an extruded aluminium barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this EOL unit with the SAU63X350S, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread and SC-series mounting.
The SAU upgrade keeps the body, bore, stroke and force identical, but modernises the sensor groove. Your original -S magnet worked with legacy CS1-B/DS1-B switches, whereas the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X350S 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 SU63X350S Is Used
Package Diverting
Pushes heavy cartons off a sorting line using the 1559N push force at 0.5MPa, with the 350mm stroke clearing the belt width.
Clamp Actuation
Secures medium-weight workpieces in machining fixtures, relying on adjustable 21mm air cushions to decelerate the 20mm rod.
Replacing the Airtac SU63-100 Standard Cylinder SU63X350S with the SAU63X350S
To replace the discontinued SU63X350S, order the SAU63X350S. Verify your 3/8" port thread (PT, G or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC) as they interchange directly. Because this SKU includes the -S magnet, note the mandatory sensor family change: legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU. If your application needs a higher force, the neighbouring 80mm bore provides 2513N push at 0.5MPa; if less is required, the 50mm bore offers 982N. For the 350mm stroke, use external guides to prevent rod-bending under side loads. A plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for load holding. If self-switching is needed, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU63X350S
- ✓ 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 SU63X350S FAQ
Yes, the AirTAC SU63X350S is discontinued and end-of-life. The direct replacement is the SAU63X350S. It shares the same 63mm bore, 350mm stroke, 3/8" port, output force and SC-series mounting, so it fits the same application directly.
The 63mm bore provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. Because this is the -S magnet version, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
