This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1100S, 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 SU63-100 Standard Cylinder SU63X1100S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1100S, which matches its bore, stroke, force and mounting.
The AirTAC SU63X1100S is a discontinued double-acting profile-type cylinder with a 63mm bore and 1100mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, utilizing a 20mm rod and a 3/8" port. AirTAC ended this series, making the SAU63X1100S the direct replacement, preserving the original bore, stroke, force, port size, and SC-series mounting compatibility.
Because of its 1100mm length, you must use external guides to prevent rod bending under side loads. Note that the -S magnet on this legacy model worked with CS1-B/DS1-B switches, whereas the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in valve, an option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X1100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 318 kgf | |
The SAU63X1100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 sideways on a 1.1-meter transfer line where the 1559N push force at 0.5MPa easily overcomes friction.
Sweeps finished aluminum extrusions out of a machining center over a 1100mm reach, relying on adjustable cushions to stop smoothly.
To replace this discontinued SU63X1100S, order the SAU63X1100S, confirming the 3/8" port, M16x1.5 rod thread, and SC-series mounts. If your machine used the -S magnet, you must upgrade to CMSG/DMSG/EMSG sensors. Sizing both ways: dropping to a 50mm bore yields 982N push at 0.5MPa, while stepping up to an 80mm bore provides 2513N. A plain cylinder drifts without live air, so for load holding add an external rod lock or pilot-operated check valve. Finally, at 1100mm stroke, external guides are mandatory to prevent rod bending.
Replacement checklist
Yes, the SU63X1100S is discontinued. The direct replacement is the AirTAC SAU63X1100S. It matches the 63mm bore, 1100mm stroke, 3/8" port, output force, and SC-series mounting accessories, but uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
At 0.5MPa it provides 1559N push and 1402N pull. At 0.7MPa push is 2182N, and at 0.9MPa it is 2805N. The theoretical maximum is 318kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa, speed is 30-800mm/s, and the 3/8" port is fixed by the 63mm bore.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X1100S replacement — usually within 7-8 hours.
