This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X150, 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 SU40X150
The AirTAC Airtac SU32~50 Standard Cylinder SU40X150 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 SAU40X150, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X150
The AirTAC SU40X150 is a discontinued double-acting profile-type cylinder with a 40mm bore and 150mm stroke. It delivers 628N push force at 0.5MPa via a 1/4" port. AirTAC replaced it with the SAU40X150, a direct upgrade sharing the exact bore, stroke, force, port and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. Note this non-magnet SKU cannot take a sensor, and the SAU upgrade switches to CMSG/DMSG/EMSG switches while adding a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X150 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 SAU40X150 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 SU40X150 Is Used
Component Clamping
Secures medium-duty machined parts during secondary milling operations, utilising the 879N push force available at 0.7MPa for rigid holding.
Package Diverting
Actuates a 150mm stroke diverter arm to push lightweight cardboard cartons off a main production line onto a secondary packing belt.
Pallet Stop Gate
Functions as an indexing stop gate for empty pallets entering a stretch wrapper, safely arresting momentum using the adjustable 21mm cushions.
Replacing the Airtac SU32~50 Standard Cylinder SU40X150 with the SAU40X150
To replace this SU40X150, order the SAU40X150 ensuring your 1/4" port threads (PT/G/NPT) and M12x1.25 rod end match. Because this is a non-S SKU, it cannot accept a sensor; if sensing is needed on the SAU, you must add the magnet and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For loads needing holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. At 150mm stroke, side-load is minimal, but always guide the load. If you need more force, the 50mm bore yields 982N push at 0.5MPa; if less is acceptable, the 32mm bore provides 402N. The SAUF variant offers a built-in 4M solenoid valve if integrated switching is desired.
Replacement checklist
- ✓ Same bore / stroke → SAU40X150
- ✓ 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 SU40X150 FAQ
Yes, the SU40X150 is discontinued. The direct replacement is the AirTAC SAU40X150. It shares the identical 40mm bore, 150mm stroke, 628N force at 0.5MPa, 1/4" port size, and SC-series mounting accessories, so it fits the same application directly.
The bore delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, 1130N push at 0.9MPa, and a theoretical max of 128kgf at 1.0MPa. This specific non-magnet SKU cannot accept a sensor. If you need position detection on the SAU replacement, you must order a magnet-equipped version and use current CMSG/DMSG/EMSG switches.
