This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X45, 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 SU80X45 is a double-acting profile-type standard cylinder with a Ø80mm bore and 45mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X45, which matches its bore, stroke, force and mounting.
The AirTAC SU80X45 is a discontinued double-acting profile-type cylinder with an 80mm bore and 45mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, operating via a 3/8" port. The direct replacement is the SAU80X45, matching the bore, stroke, output force, port size, and SC-series mounting accessories.
Because this is an extruded aluminum profile barrel, it is more compact than a standard ISO 15552 cylinder of the same bore. Note this non-magnetic SKU cannot accept a sensor. The SAU upgrade uses modern CMSG/DMSG/EMSG switches and adds a SAUF built-in-valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X45 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 SAU80X45 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 high-force stamping and forming tasks utilizing 2513N of push force at 0.5MPa within a compact 45mm travel.
Pushes heavy loaded pallets off a main transfer line using the robust 25mm piston rod and 3/8" air supply.
Secures large workpieces or packaging loads firmly in place during secondary machining or banding processes.
To replace this SU80X45, order the SAU80X45. Verify your 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) which carry over directly. Since this is a non-magnet SKU, it cannot accept a sensor; if sensing is needed, specify an SAU80X45-S and migrate to CMSG/DMSG/EMSG switches. For sizing, the 80mm bore yields 2513N push at 0.5MPa; if less force is needed, a 63mm bore provides 1559N. A plain cylinder drifts on air loss—the 28mm cushions only decelerate, so use an external rod lock for held loads. The 45mm stroke is short, but for any application over 300mm, add a guide to prevent rod bending.
Replacement checklist
Yes, the AirTAC SU80X45 is discontinued. The direct replacement is the SAU80X45. It features the same 80mm bore, 45mm stroke, 3/8" port, output force, and SC-series mounting compatibility, fitting the same application directly.
The 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a theoretical max of 513kgf at 1.0MPa. This specific non-S SKU cannot take a sensor; the SAU replacement with a magnet uses CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X45 replacement — usually within 7-8 hours.
