This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X290, 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 SU63X290
The AirTAC Airtac SU63-100 Standard Cylinder SU63X290 is a double-acting profile-type standard cylinder with a Ø63mm bore and 290mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X290, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X290
The AirTAC SU63X290 is a discontinued double-acting profile-type cylinder featuring a 63mm bore and 290mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, utilizing a 20mm rod and 3/8" port. AirTAC replaced this legacy unit with the SAU63X290, a direct upgrade retaining the exact bore, stroke, output force, port size and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. If sensing is needed, the SAU replacement uses modern CMSG/DMSG/EMSG switches (the SU line relied on legacy CS1-B/DS1-B). The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X290 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU63X290 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 SU63X290 Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 1559N thrust, absorbing end-of-stroke impact via the 21mm adjustable cushion.
Clamp Actuation
Secures 79kg vertical workpieces during machining, relying on the 290mm stroke to clear the workspace for robotic loading.
Pallet Stops
Deploys a 63mm profile body stopper at roller conveyors, dropping into SC-series foot mounts to halt incoming pallets safely.
Replacing the Airtac SU63-100 Standard Cylinder SU63X290 with the SAU63X290
To replace the SU63X290, order the SAU63X290, confirming the 3/8" port, M16x1.5 rod thread, and PT/G/NPT thread choice. Since this specific SKU has no magnet (-S), it cannot support a sensor; if position detection is required, specify an -S SAU model and migrate to CMSG/DMSG/EMSG switches. Sizing both ways: a 50mm bore provides 982N push at 0.5MPa, while an 80mm bore yields 2513N, compared to this 63mm bore's 1559N. At 290mm stroke, ensure adequate guidance to prevent rod bending under side loads. The air cushion only decelerates the piston near stroke end; it does not hold the load. For static holding upon air loss, install an external rod lock or pilot-operated check valve. The SAUF valve-integrated option can also simplify actuation circuits.
Replacement checklist
- ✓ Same bore / stroke → SAU63X290
- ✓ 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 SU63X290 FAQ
Yes, the SU63X290 is discontinued. The direct replacement is the AirTAC SAU63X290. It matches the 63mm bore, 290mm stroke, 3/8" port, output force, and SC-series mounting accessories, fitting the same application space.
It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. This specific SKU has no magnet, so it cannot take a sensor; the SAU replacement with an -S option uses CMSG/DMSG/EMSG switches.
