This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X600STC, 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 Airtac SU63-100 Standard Cylinder SU80X600STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 600mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X600STC, which matches its bore, stroke, force and mounting.
The AirTAC SU80X600STC is a discontinued double-acting profile-type cylinder with an 80mm bore and 600mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, utilizing a 3/8" port and M20x1.5 rod thread. The direct replacement is the SAU80X600STC, matching the bore, stroke, force, port, and SC-series mounting.
This extruded aluminum body is shorter than an ISO 15552 equivalent. The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches on this -S model, and adds the SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X600STC 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 SAU80X600STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×600 | 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 laterally across a transfer line using the 2513N push force at 0.5MPa, while the 600mm stroke clears the main conveyor width.
Ejects dense machined metal components from a press bed, relying on the 28mm adjustable air cushions to decelerate the rod at stroke end.
To replace the SU80X600STC, order the SAU80X600STC, verifying the 80mm bore, 600mm stroke, 3/8" port, and TC mounting interface. Because this -S SKU has a piston magnet, note that the legacy CS1-B/DS1-B switches are obsolete and you must use CMSG/DMSG/EMSG sensors on the SAU. For neighboring bores, a 63mm yields 1559N [email protected] while a 100mm yields 3927N. At 600mm, prevent rod bending by adding an external guide to absorb side loads. A plain cylinder drifts without live air, so use an external rod lock for held loads.
Replacement checklist
Yes, the SU80X600STC is discontinued. The direct replacement is the SAU80X600STC, which matches the 80mm bore, 600mm stroke, 3/8" port, output force, and SC-series TC mounting accessories.
It provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf max at 1.0MPa. Because this is an -S model, the legacy CS1-B/DS1-B switches are retired; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X600STC replacement — usually within 7-8 hours.
