This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X500TC, 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 SU100X500TC is a double-acting profile-type standard cylinder with a Ø100mm bore and 500mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X500TC, which matches its bore, stroke, force and mounting.
The AirTAC SU100X500TC is a discontinued double-acting profile-type cylinder with a 100mm bore and 500mm stroke. It delivers a robust 3927 N push force at 0.5 MPa (801 kgf maximum at 1.0 MPa) and features a 1/2 inch air port. AirTAC replaced this legacy unit with the SAU100X500TC, a direct replacement retaining the exact bore, stroke, output force, port size, and TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a position switch. The SAU upgrade also drops support for the older CS1-B/DS1-B sensors in favor of current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in valve variant.

| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X500TC 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.
Ideal for driving large stamping or forming presses where the 801 kgf maximum thrust at 1.0 MPa is required to shape heavy metal components securely.
Actuates heavy-duty diverter arms on high-capacity conveyor lines, utilizing the 500mm stroke to clear wide product flows efficiently.
To replace the discontinued SU100X500TC, order the SAU100X500TC and verify your 1/2 inch port threads (PT, G, or NPT) along with the SC-series TC mounting accessory. Since this specific SKU has no magnet (-S), it cannot support sensing; if you require position detection on the new unit, you must select an SAU model with the magnet option and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. When sizing, note a neighboring 80mm bore yields 2513 N push at 0.5 MPa, whereas this 100mm bore provides 3927 N, giving you substantial thrust headroom. For the 500mm stroke, external guides are strongly recommended to prevent rod bending under side loads. Finally, remember this cylinder will not hold a load without live air—the cushions only decelerate—so add an external rod lock or pilot-operated check valve for vertical holding.
Replacement checklist
Yes, the AirTAC SU100X500TC is discontinued. The direct replacement is the SAU100X500TC. It matches the original 100mm bore, 500mm stroke, output force, 1/2 inch port, and TC mounting, so it fits the same application without mechanical modifications.
At 0.5 MPa it provides 3927 N push and 3681 N pull; at 0.7 MPa it pushes 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. The 29mm adjustable cushions only decelerate the piston near stroke end and do not hold the load on air loss. For vertical applications, you must use an external rod lock or pilot-operated check valve.
