This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X130S, 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 SU40X130S is a double-acting profile-type standard cylinder with a Ø40mm bore and 130mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X130S, which matches its bore, stroke, force and mounting.
The AirTAC SU40X130S is a discontinued double-acting profile-type cylinder with a 40mm bore and 130mm stroke. Built with an extruded aluminum barrel and adjustable air cushions at both ends, it delivers 628N push force at 0.5MPa via a 1/4" port. AirTAC replaced this legacy unit with the SAU40X130S, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this model's legacy CS1-B/DS1-B switches, and also offers the SAUF valve-integrated variant. Remember that the air cushion only decelerates the piston; it does not hold loads on air loss, so use an external rod lock for vertical holding.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X130S 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.
Ideal for securing mid-weight machined parts during milling or drilling, utilizing the 628N push force at 0.5MPa for rigid hold-down.
Drives short-stroke sorting gates on packaging lines, where the 130mm travel and 32kg safe vertical lift capacity easily redirect goods.
Acts as a pneumatic stop mechanism in low-profile material handling conveyors, benefiting from the compact extruded barrel design.
To replace this discontinued SU40X130S, order the SAU40X130S, confirming the 40mm bore, 130mm stroke, 1/4" port, M12x1.25 rod thread, and SC-series mounting. Because this SKU includes a magnet (-S), you must upgrade your sensors: the legacy CS1-B/DS1-B switches are replaced by the current CMSG/DMSG/EMSG family on the SAU. When sizing, check neighboring bores (32mm or 50mm) if your force needs change, noting the 50mm bore provides 982N push at 0.5MPa versus this 40mm bore's 628N. If your application requires self-switching, the SAU family offers the SAUF variant with a built-in 4M solenoid valve. For any load holding, add an external rod lock or pilot-operated check valve, as standard cushions only decelerate. At 130mm stroke, side-load risks are low, but ensure correct alignment to prevent rod bending.
Replacement checklist
Yes, the AirTAC SU40X130S is discontinued and end-of-life. The direct replacement is the SAU40X130S. It shares the identical 40mm bore, 130mm stroke, 628N force, 1/4" port, and SC-series mounting accessories, so it fits the same application directly.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU40X130S replacement requires upgrading to the current CMSG/DMSG/EMSG sensor family.
