This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X100STC, 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 SU63X100STC
The AirTAC SU63-100 Standard Cylinder SU63X100STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X100STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X100STC
The AirTAC SU63X100STC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 100 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, operating at 30-800 mm/s through a 3/8" port. AirTAC replaced this EOL unit with the SAU63X100STC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
When upgrading to the SAU63X100STC, your body dimensions and M16x1.5 rod thread remain identical, but the legacy CS1-B/DS1-B sensors on this -S model must change to the current CMSG/DMSG/EMSG family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked.

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 SAU63X100STC 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 SU63X100STC Is Used
Package Diverting
Drives TC-mounted diverting arms on packaging lines, utilizing the 1559 N push force at 0.5 MPa to redirect heavy cartons reliably at speed.
Pallet Stopper Gate
Acts as a pneumatic stop gate for medium-weight pallets, where the 100 mm stroke provides sufficient extension without excessive footprint.
Material Pressing
Applies downward clamping pressure on workholding fixtures, safely handling loads up to 935 N while maintaining a compact profile body.
Replacing the Airtac SU63-100 Standard Cylinder SU63X100STC with the SAU63X100STC
To replace this discontinued SU63X100STC, order the SAU63X100STC ensuring your 3/8" port, M16x1.5 rod thread, and TC mounting accessory carry over directly. Because this SKU includes a magnet (-S), note that your legacy CS1-B/DS1-B switches are incompatible with the SAU groove and must be upgraded to CMSG/DMSG/EMSG sensors. If your application requires integrated flow control, explore the SAUF valve-integrated variant. For sizing alternatives, dropping to a 50 mm bore yields 982 N push at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N. Remember that a standard cylinder drifts without live air; the adjustable 21 mm cushions only decelerate the piston near stroke end, so add an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU63X100STC
- ✓ 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 SU63X100STC FAQ
Yes, the AirTAC SU63X100STC is discontinued and end-of-life. The direct replacement is the SAU63X100STC. It shares the identical 63 mm bore, 100 mm stroke, 3/8" port, and TC mounting interface, meaning it drops directly into the same application without mechanical modifications.
This double-acting cylinder provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa. Because this model includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to the current CMSG/DMSG/EMSG sensor family.
