This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X185S, 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 SU80X185S is a double-acting profile-type standard cylinder with a Ø80mm bore and 185mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X185S, which matches its bore, stroke, force and mounting.
The AirTAC SU80X185S is a discontinued double-acting profile-type cylinder with an 80mm bore and 185mm stroke. Delivering 2513N push force at 0.5MPa, its direct replacement is the SAU80X185S, matching the 3/8" port, M20x1.5 rod thread, and SC-series mounting.
The SAU upgrade retains the compact extruded aluminum body but switches the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X185S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X185S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×185 | Stroke length in mm. |
| -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 off a main conveyor line utilizing the 2513N thrust and 185mm travel distance.
Ejects completed cardboard stacks from a packing zone, requiring the 80mm bore's high push force.
Kicks formed metal parts out of a light stamping press using the 185mm stroke and robust 25mm rod.
To replace this SU80X185S, order the SAU80X185S, confirming the 80mm bore, 185mm stroke, 3/8" port, and PT/G/NPT thread choice. Reuse your existing SC-series mounting brackets. Because this is an -S magnet model, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. For sizing alternatives, dropping to a 63mm bore yields 1559N push at 0.5MPa, while an 80mm bore at 0.7MPa provides 3518N. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock for held loads. If you need faster local actuation, consider the SAUF variant with its integrated 4M solenoid valve.
Replacement checklist
Yes, the SU80X185S is discontinued. The direct replacement is the SAU80X185S. It shares the same 80mm bore, 185mm stroke, output force, 3/8" port, and SC-series mounting, but the -S magnet requires upgrading from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The 80mm bore features a 3/8" air port. It generates 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a theoretical maximum of 513kgf at 1.0MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X185S replacement — usually within 7-8 hours.
