This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X400, 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 SU100X400
The AirTAC Airtac SU63-100 Standard Cylinder SU100X400 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 SAU100X400, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X400
The AirTAC SU100X400 is a discontinued double-acting profile-type cylinder with a 100mm bore and 400mm stroke. It delivers a 3927 N push force at 0.5 MPa, utilizing a 25mm piston rod and a 1/2" port. AirTAC replaced this end-of-line unit with the SAU100X400, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
Because this SKU lacks a magnet, it cannot accept a sensing switch. The SAU upgrade introduces modern CMSG/DMSG/EMSG sensors for magnet-equipped variants, plus a new SAUF built-in 4M valve option the SU line never offered. Note that a standard cylinder drifts without live air; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X400 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU100X400 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 SU100X400 Is Used
Heavy Press Clamping
Secures large metal castings in machining fixtures, using the 3927 N push force at 0.5 MPa to prevent workpiece shifting under high spindle loads.
Mold Ejection Systems
Drives thick industrial mold cores out of injection machinery, relying on the 25mm rod and 1/2" port to rapidly cycle large volumes of compressed air.
Replacing the Airtac SU63-100 Standard Cylinder SU100X400 with the SAU100X400
To replace the discontinued SU100X400, order the SAU100X400 direct equivalent, verifying your 1/2" port, M20x1.5 rod thread, and SC-series mounting hardware. Since this specific SKU has no magnet (-S), it cannot support sensors; if position detection is needed, specify an SAU100X400-S and migrate to CMSG/DMSG/EMSG switches. For the 400mm stroke, prevent rod bending by ensuring external guide rails to handle side loads. Finally, remember the air cushion only decelerates near stroke end; add a pilot-operated check valve to hold loads securely.
Replacement checklist
- ✓ Same bore / stroke → SAU100X400
- ✓ 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 SU100X400 FAQ
Yes, the AirTAC SU100X400 is discontinued. The direct replacement is the SAU100X400. It shares the identical 100mm bore, 400mm stroke, 1/2" port, output force, and SC-series mounting hardware, so it fits the same application directly.
This double-acting cylinder provides 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 specific SKU lacks a magnet, it cannot accept a sensing switch; magnet-equipped variants use CMSG/DMSG/EMSG sensors on the SAU series.
