This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X312SN, 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 SU100X312SN
The AirTAC SU63-100 Standard Cylinder SU100X312SN is a double-acting profile-type standard cylinder with a Ø100mm bore and 312mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X312SN, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X312SN
The AirTAC SU100X312SN is a discontinued double-acting profile-type cylinder with a 100 mm bore and 312 mm stroke. It delivers a robust 3927 N push force at 0.5 MPa, utilizing a 1/2" port and a 25 mm piston rod. AirTAC ended this line, making the direct replacement the SAU100X312SN, which preserves the exact bore, stroke, output force, port size, and SC-series mounting accessories.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked. This unit features NBR (-N) seals suitable for -20 to +70 C.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X312SN 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 SU100X312SN Is Used
Heavy Stamp Press Feed
Pushes thick metal blanks into a hydraulic press, utilizing the 3927 N thrust at 0.5 MPa to move heavy stock reliably.
Large Mold Actuation
Opens and closes heavy resin molds on an injection machine, where the 312 mm stroke accommodates deep part extraction.
Replacing the Airtac SU63-100 Standard Cylinder SU100X312SN with the SAU100X312SN
To replace this discontinued SU100X312SN, order the SAU100X312SN direct equivalent, verifying your 1/2" port, M20x1.5 rod thread, and SC-series mounting hardware. If your current setup uses the -S magnet with legacy CS1-B/DS1-B switches, you must migrate to CMSG/DMSG/EMSG sensors on the new SAU body. If you need integrated airflow control, explore the SAUF valve-integrated option. Sizing context: this 100 mm bore provides 3927 N push at 0.5 MPa (801 kgf max at 1.0 MPa); dropping to an 80 mm bore drops force to 2513 N. Note that 312 mm exceeds standard stroke increments, requiring nonstandard_stroke = true. At this length, side-load and rod-bending risks increase, so external guide rails are recommended to prevent premature seal wear. Finally, a plain cylinder drifts on air loss—the 29 mm adjustable cushions only decelerate near stroke end—so add an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU100X312SN
- ✓ 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 SU100X312SN FAQ
Yes, the SU100X312SN is discontinued. The direct replacement is the SAU100X312SN. It matches the 100 mm bore, 312 mm stroke, 1/2" port, output force, and SC-series mounting. You just order the SAU equivalent.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa. Because this model has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
