This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1100STC, 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 SU63X1100STC 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 SAU63X1100STC, which matches its bore, stroke, force and mounting.
The AirTAC SU63X1100STC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 1100 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU63X1100STC, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series TC mounting interface.
The SAU upgrade switches the legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in 4M solenoid valve option the SU line lacked. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X1100STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 318 kgf | |
The SAU63X1100STC 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.
Ejects pallets from deep racking bays where the 63 mm bore provides adequate force without excessive width.
Shifts workpieces between distant machining stations, guided externally to prevent rod bending over 1100 mm.
To replace this SU63X1100STC, order the SAU63X1100STC. Verify your 3/8" port, M16x1.5 rod thread, and SC-series TC mounting accessory. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. At 1100 mm stroke, prevent rod bending by using an external guide to absorb side loads. A plain cylinder drifts on air loss—the 21 mm cushion only decelerates; for load holding, add an external rod lock or pilot-operated check valve. If you need self-switching, explore the SAUF valve-integrated variant.
Replacement checklist
Yes, the SU63X1100STC is discontinued. The direct replacement is the SAU63X1100STC. It matches the 63 mm bore, 1100 mm stroke, 3/8" port, and TC mounting. The SAU also retains the same profile body and force, but uses current CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B.
The 63 mm bore uses a 3/8" port. It generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X1100STC replacement — usually within 7-8 hours.
