This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X750, 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 SU100X750
The AirTAC SU63-100 Standard Cylinder SU100X750 is a double-acting profile-type standard cylinder with a Ø100mm bore and 750mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X750, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X750
The AirTAC SU100X750 is a discontinued double-acting profile-type cylinder with a 100mm bore and 750mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa, operating at 30-800 mm/s with a 1/2" port. AirTAC replaced this end-of-line unit with the SAU100X750, a direct upgrade retaining the exact body dimensions, force, and SC-series mounting.
The SAU replacement modernizes sensing by adopting CMSG, DMSG, or EMSG switches instead of the legacy CS1-B/DS1-B reed sensors. Because this specific SKU lacks a magnet, it cannot accept any sensor. Note that the SAU family introduces a SAUF variant with a built-in 4M solenoid valve, an option the original SU line never offered.

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 SAU100X750 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 SU100X750 Is Used
Heavy Stamping Press
Drives heavy tooling beds with 3927 N push at 0.5 MPa, utilizing the 750mm travel for deep-draw forming operations.
Bulk Material Diverter
Actuates large routing gates on aggregate conveyors, requiring the robust 1/2" port flow and 100mm bore capacity.
Replacing the Airtac SU63-100 Standard Cylinder SU100X750 with the SAU100X750
To replace this discontinued SU100X750, order the SAU100X750. Verify your 1/2" port, M20x1.5 rod thread, and SC-series mounting accessories, as these remain identical. Sizing alternatives: a 100mm bore yields 3927 N push at 0.5 MPa, while stepping down to an 80mm bore drops thrust to 2513 N. Since this is a 750mm stroke, support the rod with external guides to prevent side-load bending. The air cushions only decelerate the piston near end-of-stroke; they do not hold load. For vertical or suspended loads without live air, install an external rod lock or pilot-operated check valve. This non-magnet SKU cannot support sensing, but if you need position detection on the SAU, order the -S option and use CMSG/DMSG/EMSG switches.
Replacement checklist
- ✓ Same bore / stroke → SAU100X750
- ✓ 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 SU100X750 FAQ
Yes, the SU100X750 is discontinued. The direct replacement is the AirTAC SAU100X750. It matches the 100mm bore, 750mm stroke, 3927 N force, 1/2" port, and SC-series mounting. The SAU body is identical, so no mechanical redesign is needed.
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 position sensors; the SAU upgrade uses CMSG/DMSG/EMSG switches for its -S magnet variant.
