This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X28, 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 SU80X28 is a double-acting profile-type standard cylinder with a Ø80mm bore and 28mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X28, which matches its bore, stroke, force and mounting.
The AirTAC SU80X28 is a discontinued double-acting profile-type cylinder with an 80mm bore and 28mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, operating at 30-800mm/s with a 3/8" port. The direct replacement is the SAU80X28, matching the bore, stroke, force, port, and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. Note this non-magnet SKU cannot take a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches and offers a new SAUF valve-integrated variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X28 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X28 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 high-force 2513N clamping of heavy steel plates in fabrication jigs using the compact 28mm stroke.
Provides robust 80mm bore actuation to pivot heavy package diverters on high-throughput conveyor lines.
Generates reliable push force to eject dense molded parts from small press dies within a tight machinery footprint.
To replace this discontinued SU80X28, order the SAU80X28 direct equivalent, verifying the 3/8" port, M20x1.5 rod thread, and SC-series mounting. Because this SKU lacks a magnet (-S), it cannot accept a sensor; if sensing is needed, specify an SAU-S model and upgrade to CMSG/DMSG/EMSG switches. For sizing, the 80mm bore yields 2513N push at 0.5MPa, while a 63mm neighbour provides 1559N. A plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock for held loads. The SAUF built-in-valve option can simplify short-stroke actuation.
Replacement checklist
Yes, the SU80X28 is discontinued. The direct replacement is the SAU80X28, which matches the 80mm bore, 28mm stroke, 3/8" port, force, and SC-series mounting. The SAU body is a direct fit, though if you need a magnet, the SAU uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
At 0.5MPa it pushes 2513N and pulls 2268N. At 0.7MPa push is 3518N, and at 0.9MPa it is 4523N. The theoretical maximum is 513kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa, speed is 30-800mm/s, and the air cushion only decelerates the load—it does not hold position without live air.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X28 replacement — usually within 7-8 hours.
