This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X535S, 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 SU63-100 Standard Cylinder SU80X535S is a double-acting profile-type standard cylinder with a Ø80mm bore and 535mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X535S, which matches its bore, stroke, force and mounting.
The AirTAC SU80X535S is a discontinued double-acting profile-type cylinder with an 80mm bore and 535mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa, rising to 3518 N at 0.7 MPa. The direct replacement is the SAU80X535S, matching the bore, stroke, force, 3/8" port and SC-series mounting.
This extruded aluminium profile is more compact than an ISO 15552 equivalent. The SAU upgrade switches the -S magnet from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in-valve variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X535S 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 SAU80X535S 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.
Pushes heavy pallets sideways onto parallel conveyor lines using the 2513 N thrust at 0.5 MPa, with the 535mm stroke clearing wide transfer beds.
Ejects completed cardboard stacks from packaging stations, where the 128 kg vertical lift capacity handles substantial material weight.
Kicks formed metal parts out of light presses, utilising the 28mm adjustable air cushions to decelerate the tooling smoothly at stroke ends.
To replace this SU80X535S, order the SAU80X535S keeping the 80mm bore, 535mm stroke, 3/8" port, M20x1.5 rod thread and SC-series mounts. If downsizing, a 63mm bore yields 1559 N push at 0.5 MPa; if upsizing, a 100mm bore yields 3927 N. Because the stroke is 535mm, fit an external guide to prevent rod bending under side loads. Note the -S magnet requires CMSG/DMSG/EMSG switches on the SAU. A plain cylinder drifts on air loss—the cushion only decelerates—so add a rod lock or pilot check valve to hold loads. The SAUF valve-integrated option can simplify cycling.
Replacement checklist
Yes, the AirTAC SU80X535S is discontinued. The direct replacement is the SAU80X535S. It matches the 80mm bore, 535mm stroke, force, 3/8" port and SC-series mounting, so it fits the same application.
The SAU80X535S provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The -S magnet on the original SU used legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X535S replacement — usually within 7-8 hours.
