This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X225S, 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 SU100X225S is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X225S, which matches its bore, stroke, force and mounting.
The AirTAC SU100X225S is a discontinued double-acting profile-type cylinder with a 100mm bore and 225mm stroke. It delivers a robust 3927 N push force at 0.5 MPa. AirTAC replaced this EOL unit with the SAU100X225S, a direct upgrade retaining the exact 1/2" port, M20x1.5 rod thread, body dimensions, and SC-series mounting hardware.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU replacement transitions to modern CMSG/DMSG/EMSG sensors. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

The SAU100X225S 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.
Drives large metalforming presses and stamping dies requiring high thrust, utilizing the 3927 N push force at 0.5 MPa to deform thick materials reliably.
Indexes heavy loaded pallets on conveyor lines, providing the robust physical push needed to overcome friction and inertia in automated distribution hubs.
Secures oversized automotive or structural components during machining and welding operations, maintaining rigid positioning under heavy cutting forces.
To replace this SU100X225S, order the SAU100X225S. Verify your port thread (PT, G, or NPT on the 1/2" port), the M20x1.5 rod-end thread, and your SC-series mounting brackets (LB, FA, FB, CA, CB, TC). Because this is a -S model, note the sensor family change: legacy CS1-B/DS1-B switches will not fit the SAU groove, so upgrade to CMSG/DMSG/EMSG sensors. If you need higher force, the neighboring 80mm bore yields 2513 N push at 0.5 MPa, while this 100mm bore hits 5497 N at 0.7 MPa. At 225mm stroke, side-load risks are low, but always guide the load to prevent rod bending. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the 29mm adjustable air cushions only decelerate and will not hold a load. If self-switching is needed, consider the new SAUF valve-integrated variant.
Replacement checklist
Yes, the SU100X225S is discontinued. The direct replacement is the AirTAC SAU100X225S. It shares the identical 100mm bore, 225mm stroke, 1/2" port, output force, and SC-series mounting accessories, so it fits the same application directly.
At 0.5 MPa it provides 3927 N push and 3681 N pull force, rising to 5497 N push at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. This -S model has a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors instead.
