This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X230S, 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 SU80X230S is a double-acting profile-type standard cylinder with a Ø80mm bore and 230mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X230S, which matches its bore, stroke, force and mounting.
The AirTAC SU80X230S is a discontinued double-acting profile-type cylinder featuring an 80mm bore, 230mm stroke, and a built-in piston magnet. It delivers 2513N push and 2268N pull at 0.5MPa, making way for the direct replacement: the SAU80X230S. You keep the same 3/8 port, M20x1.5 rod thread, output force, and SC-series mounting accessories.
The SAU upgrade retains the compact extruded aluminum body, shorter than an ISO 15552 cylinder of the same bore, while introducing current CMSG/DMSG/EMSG sensors to replace this legacy model's CS1-B/DS1-B switches. Note that a plain cylinder drifts on air loss; the cushions only decelerate, so use an external rod lock for held loads.

| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X230S 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 diverting arms on high-throughput packaging conveyors, utilizing the 230mm stroke to push heavy cartons cleanly off the main belt.
Acts as a robust pneumatic stop for loaded pallets on roller conveyors, easily handling the kinetic energy within its 2513N force class.
Ejects formed metal or plastic parts from mid-sized press dies, where the compact profile body saves valuable machine footprint.
To replace this SU80X230S, order the SAU80X230S direct equivalent, verifying your 3/8 port, PT/G/NPT thread choice, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU has the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensor family. If you need integrated air control, the SAU line offers the SAUF variant with a built-in 4M solenoid valve, which the SU series lacked. For sizing both ways, a neighboring 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore provides 3927N. At 230mm stroke, side-load risks are moderate, but always guide the load to prevent rod bending. Remember, the 28mm adjustable air cushions only decelerate; they do not hold the load without live air.
Replacement checklist
Yes, the SU80X230S is discontinued and end-of-life. The direct replacement is the AirTAC SAU80X230S. It matches the 80mm bore, 230mm stroke, 3/8 port, output force, and SC-series mounting, so it fits the same application. You just order the SAU equivalent.
This 80mm bore cylinder delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a theoretical max of 513kgf at 1.0MPa. Because this is the -S magnet version, it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to the current CMSG/DMSG/EMSG sensor family.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X230S replacement — usually within 7-8 hours.
