This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X150FA, 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 SU40X150FA
The AirTAC Airtac SU32~50 Standard Cylinder SU40X150FA 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 SAU40X150FA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X150FA
The AirTAC SU40X150FA is a discontinued double-acting profile-type cylinder with a 40mm bore and 150mm stroke. It delivers 628 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU40X150FA, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series FA mounting interface.
Because this SKU lacks a magnet (-S), it cannot accept position sensors. The SAU upgrade introduces compatibility with modern CMSG/DMSG/EMSG switches (if you order the -S version) and adds a SAUF built-in 4M valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X150FA 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 SAU40X150FA 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.
Where the Airtac SU32~50 Standard Cylinder SU40X150FA Is Used
Package Diverting
Drives a 150 mm diverting arm on a packaging line, utilizing the 628 N push force at 0.5 MPa to reliably push cartons onto adjacent conveyors.
Clamp Actuation
Provides repeatable 150 mm travel for secondary clamping operations on a CNC fixture, where the compact profile body saves valuable workspace.
Stopper Gate
Acts as a pneumatic stopper gate for pallet accumulation, using the FA foot mount to securely handle the impact of incoming pallet loads.
Replacing the Airtac SU32~50 Standard Cylinder SU40X150FA with the SAU40X150FA
To replace this SU40X150FA, order the SAU40X150FA. Confirm your 1/4" port thread (PT, G, or NPT) and the M12x1.25 rod-end thread. The FA foot mount is an SC-series accessory that transfers over directly. If you need position sensing, note this specific non-magnetic SKU cannot take a switch; you must specify an -S SAU model and migrate from the old CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. At 150 mm stroke, side-load risk is moderate, but ensure adequate guiding to prevent rod bending. For loads needing 879 N at 0.7 MPa, the 40 mm bore is ideal; if dropping to a 32 mm bore yields insufficient force (402 N push), keep the 40 mm. Remember, the 21 mm adjustable air cushions only decelerate the piston near stroke end—they do not hold the load. For static holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU40X150FA
- ✓ 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 SU40X150FA FAQ
Yes, the SU40X150FA is discontinued. The direct replacement is the AirTAC SAU40X150FA. It shares the same 40 mm bore, 150 mm stroke, 1/4" port, output force, and SC-series FA mounting accessories, allowing for a seamless physical swap.
This 40 mm bore cylinder provides 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a theoretical maximum of 128 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept legacy CS1-B/DS1-B sensors; if sensing is required, order the SAU replacement with the -S option and use current CMSG/DMSG/EMSG switches.
