This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X70, 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 SU100X70
The AirTAC Airtac SU63-100 Standard Cylinder SU100X70 is a double-acting profile-type standard cylinder with a Ø100mm bore and 70mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X70, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X70
The AirTAC SU100X70 is a discontinued double-acting profile-type cylinder with a 100mm bore and 70mm stroke. Delivering a robust 3927 N push force at 0.5 MPa, it features a 25mm piston rod, M20x1.5 rod thread, and a fixed 1/2" port. AirTAC replaced this EOL unit with the SAU100X70, a direct alternative retaining the exact same body dimensions, output force, and SC-series mounting compatibility.
Because this specific SKU lacks a magnet (-S), it cannot accept position sensors. If sensing is needed, the SAU100X70 upgrade uses modern CMSG/DMSG/EMSG switches (the legacy SU line required CS1-B/DS1-B). Note that a standard cylinder drifts without live air; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X70 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 SAU100X70 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 SU100X70 Is Used
Heavy Stamp Pressing
Ideal for driving heavy stamping dies with 3927 N of thrust at 0.5 MPa, utilizing the 70mm stroke for rapid metalforming cycles.
Pallet Diverting
Provides the robust push force needed to redirect loaded pallets on conveyors, taking advantage of the 1/2 inch port for high flow.
Replacing the Airtac SU63-100 Standard Cylinder SU100X70 with the SAU100X70
To replace the SU100X70, order the SAU100X70 direct equivalent, verifying your 1/2" port, M20x1.5 thread, and SC-series mounting hardware. This non-magnetic SKU cannot support sensors; if you need position detection, specify an SAU100X70-S and adopt the current CMSG/DMSG/EMSG switch family instead of the obsolete CS1-B/DS1-B. If downsizing, a 80mm bore yields 2513 N push at 0.5 MPa; if upscaling, no larger standard profile body exists. Remember that air cushions only decelerate the piston near stroke end and do not hold loads on air loss—install a pilot-operated check valve or rod lock for vertical holding. For actuation speeds of 30-800 mm/s, the SAUF variant offers a built-in 4M solenoid valve for self-switching, an option the SU line never had.
Replacement checklist
- ✓ Same bore / stroke → SAU100X70
- ✓ 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 SU100X70 FAQ
Yes, the AirTAC SU100X70 is discontinued and end-of-life. The direct replacement is the SAU100X70. It shares the identical 100mm bore, 70mm stroke, 1/2" port, 3927 N force, and SC-series mounting, so it drops right into the same application.
This 100mm bore cylinder delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot take sensors; the SAU replacement uses CMSG/DMSG/EMSG switches.
