This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X120, 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 SU80X120 is a double-acting profile-type standard cylinder with a Ø80mm bore and 120mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X120, which matches its bore, stroke, force and mounting.
The AirTAC SU80X120 is a discontinued double-acting profile-type cylinder with an 80mm bore and 120mm stroke. Delivering 2513N push and 2268N pull at 0.5MPa, it features a 3/8" port and a 25mm piston rod. AirTAC replaced this unit with the SAU80X120, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade uses current CMSG/DMSG/EMSG switches and adds a SAUF built-in-valve option. The extruded aluminium body is more compact than an ISO 15552 cylinder.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X120 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 SAU80X120 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 medium-duty bushing and bearing insertion presses requiring 2513N of push force at 0.5MPa within a compact 120mm stroke.
Actuates heavy-duty routing gates and pusher arms on packaging lines, handling inertial loads safely with 28mm adjustable cushions.
Deploys robust end-of-line stops for loaded pallets, utilising the 2268N pull force to retract the barrier and clear the conveyor path.
To replace the SU80X120, order the SAU80X120, confirming the 3/8" port, M20x1.5 rod thread and SC-series mounting. This non-magnetic SKU cannot take a switch; if sensing is needed, specify an SAU-S magnet and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. The 120mm stroke is under the 1500mm standard limit, so no side-load guide is required. For sizing both ways: a 63mm bore yields 1559N [email protected], while a 100mm bore yields 3927N. Note that a plain cylinder drifts on air loss—the cushions only decelerate—so use a rod lock or pilot check valve to hold loads.
Replacement checklist
Yes, the AirTAC SU80X120 is discontinued. The direct replacement is the SAU80X120. It shares the identical 80mm bore, 120mm stroke, 2513N output force, 3/8" port and SC-series mounting, so it fits the same application without mechanical modifications.
At 0.5MPa it provides 2513N push and 2268N pull, rising to 3518N push at 0.7MPa and a 513kgf maximum at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU replacement requires CMSG/DMSG/EMSG switches if sensing is added.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X120 replacement — usually within 7-8 hours.
