This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X95, 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.
Airtac SU32~50 Standard Cylinder SU40X95
The AirTAC SU32~50 Standard Cylinder SU40X95 is a double-acting profile-type standard cylinder with a Ø40mm bore and 95mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X95, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X95
The AirTAC SU40X95 is a discontinued double-acting profile-type cylinder with a 40 mm bore and 95 mm stroke. It delivers 628 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this unit with the SAU40X95, a direct alternative retaining the exact bore, stroke, output force, port size, M12x1.25 rod thread and SC-series mounting. You simply order the SAU equivalent.
This extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore. Because this specific SKU lacks a magnet, it cannot accept a sensor; furthermore, the SAU family upgrades sensing to CMSG/DMSG/EMSG switches and introduces the SAUF built-in-valve variant the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X95 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X95 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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.
Where the Airtac SU32~50 Standard Cylinder SU40X95 Is Used
Package Diverting
Pushes light cartons off a sorting line using the 628 N push force at 0.5 MPa, fitting neatly into existing SC-series bracket clearances.
Pallet Stops
Acts as a pneumatic stop for low-inertia pallets, where the adjustable 21 mm cushion decelerates the load smoothly at the end of the 95 mm stroke.
Replacing the Airtac SU32~50 Standard Cylinder SU40X95 with the SAU40X95
To replace this discontinued SU40X95, order the SAU40X95 direct. Verify your 1/4" port thread (PT, G or NPT) and SC-series mounting (LB, FA, FB, CA, CB). This non-magnetic SKU cannot take a switch; if you need position sensing, order an SAU40X95-S and use current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For loads approaching the 879 N push at 0.7 MPa, consider the adjacent 32 mm bore (563 N) or 50 mm bore (1374 N) alternatives. Note that a standard cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU40X95
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU32~50 Standard Cylinder SU40X95 FAQ
Yes, the AirTAC SU40X95 is discontinued. The direct replacement is the SAU40X95. It matches the 40 mm bore, 95 mm stroke, 628 N force at 0.5 MPa, 1/4" port, and SC-series mounting accessories, so it fits the same application directly.
The bore 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. This specific SKU has no magnet and cannot accept a sensor; the SAU replacement with a -S suffix uses CMSG/DMSG/EMSG switches.
