This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X70STC, 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.

The AirTAC Airtac SU63-100 Standard Cylinder SU100X70STC 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 SAU100X70STC, which matches its bore, stroke, force and mounting.
The AirTAC SU100X70STC is a discontinued double-acting profile cylinder with a 100mm bore and 70mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa, peaking at 801kgf. The direct replacement is the SAU100X70STC, matching the 1/2in port, M20x1.5 rod, and TC mounting exactly.
The SAU upgrade retains the compact extruded body but moves to CMSG/DMSG/EMSG sensors instead of the SU's CS1-B/DS1-B switches, and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X70STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X70STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| SU | Profile-type standard cylinder (discontinued). |

| 100 | Bore size in mm. |
| ×70 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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.
Secures large metal castings during machining using the 3927N push force at 0.5MPa, with the 70mm stroke accommodating part variance.
Pushes loaded pallets off a main line; the TC mount allows trunnion pivoting for angled ejection without tie-rod interference.
Ejects heavy goods from lifting forks using a compact 100mm profile body that fits tight conveyor frames while delivering 801kgf max.
To replace this SU100X70STC, order the SAU100X70STC keeping the 100mm bore, 70mm stroke, 1/2in port, and TC mount. If your machine needs more force, step up the bore; if less, drop to 80mm (2513N push @0.5MPa). The TC mount is an SC-series accessory. Because this SKU has a magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. The cylinder cannot hold a load without live air; use an external rod lock for safety. The 70mm stroke avoids rod-bending risks, but always guide side loads.
Replacement checklist
Yes, the AirTAC SU100X70STC is discontinued. The direct replacement is the SAU100X70STC. It shares the same 100mm bore, 70mm stroke, 1/2in port, force, and TC mounting interface.
It pushes 3927N and pulls 3681N at 0.5MPa, pushes 5497N at 0.7MPa, and reaches 801kgf at 1.0MPa. The SU -S magnet used CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU100X70STC replacement — usually within 7-8 hours.
