This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X400SH, 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 SU100X400SH
The AirTAC SU63-100 Standard Cylinder SU100X400SH is a double-acting profile-type standard cylinder with a Ø100mm bore and 400mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X400SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X400SH
The AirTAC SU100X400SH is a discontinued double-acting profile-type cylinder with a 100mm bore and 400mm stroke. It delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa, utilizing a 1/2 inch port and M20x1.5 rod thread. AirTAC replaced this legacy unit with the SAU100X400SH. This direct upgrade matches the original bore, stroke, output force, port size, and SC-series mounting, while the -H seal specifies Viton FKM for high-temperature environments up to 150 C.
Because the -S magnet relied on legacy CS1-B/DS1-B switches, upgrading to the SAU100X400SH requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line lacked. Note that a standard cylinder drifts without live air; the cushions only decelerate, so use an external rod lock for holding.

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 SAU100X400SH 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 SU100X400SH Is Used
Heavy Stamp Press Feed
Drives robust 200 kg material blanks into a high-temp stamping die, utilizing the 3927 N push force and Viton seals to withstand ambient heat near the machinery.
Palletized Load Ejector
Pushes heavy finished goods off a conveyor line at 0.5 MPa, relying on the 1/2 inch port for rapid air exchange and external guides to prevent rod bending over the 400mm extension.
Mold Clamping Actuator
Secures industrial molds within a 150 C thermal chamber using the high-temp -H seal, providing 3681 N pull force while maintaining position via an external check valve.
Replacing the Airtac SU63-100 Standard Cylinder SU100X400SH with the SAU100X400SH
To replace the discontinued SU100X400SH, order the SAU100X400SH direct equivalent, verifying your 1/2 inch port, M20x1.5 rod thread, and SC-series mounting hardware. If your machine used the -S magnet for positioning, you must upgrade to CMSG/DMSG/EMSG sensors since the legacy CS1-B/DS1-B switches are obsolete. The -H Viton seal is retained for 0-150 C high-temperature duty. With a 400mm stroke, prevent rod bending by guiding the load externally to avoid side-load stress. For force context, the 100mm bore yields 3927 N push at 0.5 MPa; if downsizing, a 80mm bore provides 2513 N. Remember that air cushions only decelerate; a pilot-operated check valve or rod lock is required to hold a load against pressure loss. If you need self-switching, explore the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU100X400SH
- ✓ 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 SU100X400SH FAQ
Yes, the SU100X400SH is discontinued. The direct replacement is the AirTAC SAU100X400SH. It shares the identical 100mm bore, 400mm stroke, 1/2 inch port, output force, and SC-series mounting, so it fits the same application. You just order the SAU equivalent.
At 0.5 MPa it pushes 3927 N and pulls 3681 N; at 0.7 MPa it pushes 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
