This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X100FA, 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 SU63X100FA is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X100FA, which matches its bore, stroke, force and mounting.
The AirTAC SU63X100FA is a discontinued double-acting profile-type cylinder with a 63 mm bore and 100 mm stroke. Built with an extruded aluminum barrel, it is more compact than a same-bore ISO 15552 unit and delivers 1559 N push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU63X100FA, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread, 318 kgf max force, and SC-series FA mounting interface.
This specific SKU lacks a magnet (-S) and therefore cannot accept a magnetic sensor. If sensing is needed on the SAU upgrade, you must add the magnet and use the current CMSG/DMSG/EMSG switches, as the legacy CS1-B/DS1-B sensors are obsolete. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X100FA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 318 kgf | |
The SAU63X100FA 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.
Secures heavy machined parts during milling with 1559 N of push force at 0.5 MPa, utilizing the FA foot mount for rigid positioning.
Pushes medium-weight cartons off a sorting line at 100 mm stroke, taking advantage of the compact 63 mm profile body to fit tight transfer spaces.
To replace the SU63X100FA, order the SAU63X100FA, confirming the 63 mm bore, 100 mm stroke, 3/8" port (default PT thread), and the SC-series FA foot mounting accessory. Because this legacy SKU has no magnet, it cannot support sensing; if your application requires position detection, specify the SAU63X100FA-S and migrate to CMSG/DMSG/EMSG switches. When sizing, check both directions: dropping to a 50 mm bore yields 982 N push at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N. Note that a plain cylinder drifts on air loss—the 21 mm adjustable cushions only decelerate near stroke end, so use an external rod lock or pilot-operated check valve for load holding. For automated actuation, consider the SAUF valve-integrated variant.
Replacement checklist
Yes, the SU63X100FA is discontinued. The direct replacement is the SAU63X100FA. It shares the identical 63 mm bore, 100 mm stroke, 3/8" port, 318 kgf max force, and SC-series FA mounting, so it fits the same application without mechanical changes.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, and the theoretical max is 318 kgf at 1.0 MPa. A plain cylinder cannot hold a load on air loss—the cushions only decelerate—so use an external rod lock for vertical holding.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X100FA replacement — usually within 7-8 hours.
