This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X290STC, 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 SU63X290STC
The AirTAC Airtac SU63-100 Standard Cylinder SU63X290STC 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 SAU63X290STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X290STC
The AirTAC SU63X290STC is a discontinued double-acting profile-type cylinder with a 63 mm bore, 290 mm stroke, and a 3/8" port. Delivering 1559 N push force at 0.5 MPa, it is succeeded by the SAU63X290STC direct replacement, matching the exact bore, stroke, output force, port size, and SC-series TC mounting.
The SAU upgrade retains the compact extruded aluminum body but switches the -S magnet compatibility from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. It also introduces the SAUF built-in 4M solenoid valve option.

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 SAU63X290STC 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 SU63X290STC Is Used
Package Diverting
Drives a TC-mounted diverting arm on a packaging line, utilizing the 1559 N thrust at 0.5 MPa to push heavy cartons smoothly onto auxiliary routing belts.
Clamp Actuation
Secures mid-weight aluminum castings during CNC machining, where the 290 mm stroke provides ample travel to clear the work envelope before tooling begins.
Replacing the Airtac SU63-100 Standard Cylinder SU63X290STC with the SAU63X290STC
To replace this discontinued SU63X290STC, order the SAU63X290STC ensuring your 3/8" port, M16x1.5 rod thread, and TC mounting interface match. Because this SKU includes the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the new SAU. If sizing alternatives, the adjacent 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N. At 290 mm stroke, guide the load to prevent rod bending and side-load wear. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. The SAUF valve-integrated variant is available if self-switching is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X290STC
- ✓ 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 SU63X290STC FAQ
Yes, the SU63X290STC is discontinued. The direct replacement is the SAU63X290STC. It shares the identical 63 mm bore, 290 mm stroke, 318 kgf max force, 3/8" port, and SC-series TC mounting, so it fits the same application directly.
The bore delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf max at 1.0 MPa. Because this model has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
