This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X195S, 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 SU32~50 Standard Cylinder SU40X195S is a double-acting profile-type standard cylinder with a Ø40mm bore and 195mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X195S, which matches its bore, stroke, force and mounting.
The AirTAC SU40X195S is a discontinued double-acting profile-type cylinder with a 40mm bore and 195mm stroke. Delivering 628 N push force at 0.5 MPa, it features an extruded aluminum barrel that is shorter and more compact than an ISO 15552 unit of the same bore. AirTAC replaced this EOL unit with the SAU40X195S, a direct replacement retaining the exact same body dimensions, 1/4" port, M12x1.25 rod thread, and SC-series mounting compatibility.
When upgrading, note that your -S magnet option transitions from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X195S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X195S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

|---|---|
| 40 | Bore size in mm. |
| ×195 | 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.
Actuates routing gates on packaging lines where the 628 N push force easily deflects standard cartons.
Drives small machining clamps, using the 195mm stroke to clear the work area for robotic loading.
To replace this SU40X195S, order the SAU40X195S. Verify your 1/4" port thread (PT, G, or NPT) and SC-series mounting accessories (LB, FA, FB, CA, CB, TC), as these remain identical. Because this SKU includes the -S magnet, you must update your sensing to CMSG/DMSG/EMSG switches; the old CS1-B/DS1-B sensors will not fit the new groove. If your application needs a self-switching function, consider the SAUF40 variant with its integrated valve. For loads requiring 879 N at 0.7 MPa, step up to a 50mm bore; if you need less force, a 32mm bore provides 402 N. Remember that a standard cylinder drifts without live air—the cushions only decelerate—so add an external rod lock or pilot-operated check valve for secure load holding. At 195mm stroke, side-load risks are moderate, but ensure adequate guide rails to prevent rod bending.
Replacement checklist
Yes, the SU40X195S is discontinued. The direct replacement is the AirTAC SAU40X195S. It matches the original 40mm bore, 195mm stroke, 628 N force, 1/4" port, and SC-series mounting, so it fits the same application without mechanical modifications.
The SAU40X195S delivers 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a theoretical max of 128 kgf at 1.0 MPa. Because your SU40X195S has the -S magnet, note that the SAU replacement requires CMSG/DMSG/EMSG switches; the legacy CS1-B/DS1-B sensors are not compatible.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU40X195S replacement — usually within 7-8 hours.
