This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X160, 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 SU40X160
The AirTAC SU32~50 Standard Cylinder SU40X160 is a double-acting profile-type standard cylinder with a Ø40mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X160, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X160
The AirTAC SU40X160 is a discontinued double-acting profile-type cylinder with a 40mm bore and 160mm stroke. It delivers 628N push force at 0.5MPa via a 1/4 port. AirTAC replaced it with the SAU40X160 direct replacement, retaining the exact body, force, and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. The SAU upgrade uses current CMSG/DMSG/EMSG sensors and adds a SAUF built-in-valve option. Note this non-magnet SKU cannot accept a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X160 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 SAU40X160 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 SU40X160 Is Used
Package Diverting
Ideal for pushing cartons on a 40mm bore line, providing 628N push at 0.5MPa to redirect packages without stalling the belt.
Pallet Stopping
Acts as a compact 160mm stroke end-stop for lightweight pallets, using the adjustable 21mm cushion to decelerate loads smoothly.
Clamp Actuation
Secures medium workpieces during machining, delivering 528N pull force at 0.5MPa while fitting into tight cell footprints.
Replacing the Airtac SU32~50 Standard Cylinder SU40X160 with the SAU40X160
To replace this discontinued SU40X160, order the SAU40X160 direct equivalent. Verify your 1/4 port thread (PT/G/NPT), M12x1.25 rod end, and SC-series mount (LB/FA/FB/CA/CB). Because this is a non-magnet SKU, it cannot accept a sensor; if you need detection, select an SAU-S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing alternatives, a 32mm bore yields 402N push at 0.5MPa, while a 50mm bore provides 982N. At 160mm stroke, side-load is minimal, but always guide the rod to prevent bending. A plain cylinder drifts on air loss; for load holding, install an external rod lock or pilot-operated check valve, as the 21mm cushions only decelerate. The SAUF variant integrates a 4M valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU40X160
- ✓ 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 SU40X160 FAQ
Yes, the SU40X160 is discontinued. The direct replacement is the AirTAC SAU40X160. It shares the identical 40mm bore, 160mm stroke, 628N force, 1/4 port, and SC-series mounting accessories, so it bolts right in.
It features a 1/4 port (fixed by the 40mm bore). The thrust is 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 non-magnet SKU cannot accept a sensor.
