This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X150N, 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 SU40X150N
The AirTAC SU32~50 Standard Cylinder SU40X150N is a double-acting profile-type standard cylinder with a Ø40mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X150N, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X150N
The AirTAC SU40X150N is a discontinued double-acting profile-type cylinder with a 40mm bore and 150mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore. It delivers 628N push and 528N pull at 0.5MPa via a 1/4 port. The direct replacement is the SAU40X150N, matching the bore, stroke, force, and SC-series mounting.
This NBR-sealed variant operates from -20 to +70C. Note this SKU lacks a magnet, so it cannot accept a sensor. The SAU upgrade uses current CMSG/DMSG/EMSG switches and adds a SAUF built-in-valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X150N 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 SAU40X150N 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 SU40X150N Is Used
Package Diverting
Pushes cartons at 90 degrees on a sorting line using the 628N push force at 0.5MPa, with the 150mm stroke clearing the belt width.
Pallet Stops
Acts as a pneumatic stop for lightweight pallets, where the NBR seals handle standard warehouse temperatures reliably.
Clamp Actuation
Drives a secondary clamping jaw on a machining fixture, providing 528N pull force to hold parts firmly during drilling.
Replacing the Airtac SU32~50 Standard Cylinder SU40X150N with the SAU40X150N
To replace this discontinued SU40X150N, order the SAU40X150N. Confirm the 40mm bore, 150mm stroke, 1/4 port, M12x1.25 rod thread, and SC-series mounting. Because this N-seal SKU has no magnet, it cannot take a sensor; if you need position detection on the SAU, order an -S model and migrate to CMSG/DMSG/EMSG switches. For sizing, the neighboring 32mm bore yields 402N push at 0.5MPa, while the 50mm bore yields 982N. At 150mm stroke, guide the load to prevent rod bending. The cylinder does not hold load without air; use a pilot-operated check valve. The SAUF variant integrates a 4M valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU40X150N
- ✓ 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 SU40X150N FAQ
Yes, the SU40X150N is discontinued. The direct replacement is the SAU40X150N. It shares the same 40mm bore, 150mm stroke, 628N force, 1/4 port, and SC-series mounting. The SAU also offers the SAUF built-in-valve variant.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. This specific SKU lacks a magnet, so it cannot accept a sensor. The SAU replacement with a magnet uses CMSG/DMSG/EMSG switches.
