This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X70, 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 SU32~50 Standard Cylinder SU32X70 is a double-acting profile-type standard cylinder with a Ø32mm bore and 70mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X70, which matches its bore, stroke, force and mounting.
The AirTAC SU32X70 is a discontinued double-acting profile-type cylinder with a 32mm bore and 70mm stroke, delivering 402N push force at 0.5MPa. AirTAC replaced it with the SAU32X70, a direct alternative retaining the exact body dimensions, 1/8" port, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a position switch; the SAU upgrade uses CMSG/DMSG/EMSG sensors for its -S variants and adds a SAUF built-in-valve option the SU line never had. Note that a standard cylinder drifts without live air, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X70 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X70 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×70 | 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.
Short 70mm stroke pushes lightweight cartons off a main conveyor belt into secondary packaging lanes with rapid 30-800mm/s speed.
Operates small pneumatic gates and hoppers in material hoppers, benefiting from the compact profile body that fits tight machine frames.
To replace this discontinued SU32X70, order the SAU32X70 and verify your 1/8" port thread (PT/G/NPT) alongside the M10x1.25 rod-end and SC-series mounting hardware. If you need position sensing, you must move to an SAU32X70S and use current CMSG/DMSG/EMSG switches, as this non-magnetic SU takes no sensor. For higher loads, the neighbouring 40mm bore yields 628N push at 0.5MPa; for lighter duties, the 32mm bore is ideal. A plain cylinder does not hold load on air loss, so add a pilot-operated check valve or rod lock for vertical safety. The 70mm stroke avoids rod-bending side-load issues seen in longer 300mm+ builds.
Replacement checklist
Yes, the AirTAC SU32X70 is discontinued and end-of-life. The direct replacement is the SAU32X70. It shares the identical 32mm bore, 70mm stroke, 1/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific non-magnetic SKU cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches on its -S variants, replacing the legacy CS1-B/DS1-B.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X70 replacement — usually within 7-8 hours.
