This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X800STC, 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 SU63X800STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 800mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X800STC, which matches its bore, stroke, force and mounting.
The AirTAC SU63X800STC is a discontinued double-acting profile-type cylinder with an 800 mm stroke and 63 mm bore. It delivers 1559 N push and 1402 N pull at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X800STC, a direct sharing the exact bore, stroke, force, port, and SC-series TC mounting.
The SAU upgrade switches the legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in 4M valve option. The extruded aluminum body remains shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X800STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X800STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×800 | 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.
Pushes heavy pallets laterally across transfer lines using the full 800 mm travel, relying on the 1559 N thrust at 0.5 MPa to overcome friction.
Opens and closes heavy machine guarding or industrial oven doors, utilizing the TC mount for secure mid-body trunnion pivoting.
To replace this SU63X800STC, order the SAU63X800STC keeping the 63 mm bore, 800 mm stroke, 3/8" port, M16x1.5 rod thread, and TC mounting. Because the -S magnet is present, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If you need a smaller bore, the 50 mm gives 982 N push at 0.5 MPa; for more power, the 80 mm yields 2513 N. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the 21 mm cushions only decelerate. At 800 mm, prevent rod bending by using an external guide to absorb side loads. Consider the SAUF variant if you need a built-in valve.
Replacement checklist
Yes, the SU63X800STC is discontinued. The direct replacement is the SAU63X800STC. It shares the same 63 mm bore, 800 mm stroke, 3/8" port, output force, and SC-series TC mounting, so it fits the same application. You just order the SAU equivalent.
It provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf max at 1.0 MPa. Because this SKU has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X800STC replacement — usually within 7-8 hours.
