This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X40CA, 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 SU80X40CA is a double-acting profile-type standard cylinder with a Ø80mm bore and 40mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X40CA, which matches its bore, stroke, force and mounting.
The AirTAC SU80X40CA is a discontinued double-acting profile-type cylinder with an 80mm bore and 40mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa via a 3/8" port. The direct replacement is the SAU80X40CA, matching the bore, stroke, force, port, and SC-series CA mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. Note this non-magnetic SKU cannot take a sensor. The SAU upgrade uses CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X40CA 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 SAU80X40CA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×40 | 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.
Applies 2513N of push force at 0.5MPa to seat bearings and pins in automated machining lines.
Handles robust package redirection on high-throughput conveying systems using the CA clevis mount.
To replace the SU80X40CA, order the SAU80X40CA direct: verify the 80mm bore, 40mm stroke, 3/8" port, M20x1.5 rod thread, and CA mounting. Because this SKU lacks a magnet (-S), it cannot accept a sensor. If sensing is needed, order an SAU-S model and use current CMSG/DMSG/EMSG switches instead of legacy CS1-B/DS1-B units. For loads exceeding the 1508N safe working threshold, consider the 100mm bore (3927N push @0.5MPa). A plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve to hold loads. The SAUF variant adds a built-in 4M valve if space is tight.
Replacement checklist
Yes, the AirTAC SU80X40CA is discontinued. The direct replacement is the SAU80X40CA, offering the same 80mm bore, 40mm stroke, 3/8" port, 513kgf max force, and CA mounting compatibility.
At 0.5MPa it provides 2513N push and 2268N pull, 3518N push at 0.7MPa, and a 513kgf maximum at 1.0MPa. This specific SKU has no magnet and cannot accept a sensor; the SAU-S replacement uses CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X40CA replacement — usually within 7-8 hours.
