This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X1000N, 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 SU40X1000N
The AirTAC SU32~50 Standard Cylinder SU40X1000N is a double-acting profile-type standard cylinder with a Ø40mm bore and 1000mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X1000N, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X1000N
The AirTAC SU40X1000N is a discontinued double-acting profile-type cylinder with a 40mm bore, 1000mm stroke, and NBR seals. It delivers 628 N push force at 0.5 MPa. AirTAC replaced this end-of-line unit with the SAU40X1000N, a direct alternative retaining the exact 1/4" port, M12x1.25 rod thread, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept position sensors. The SAU upgrade switches to modern CMSG/DMSG/EMSG switches if you ever need sensing, and introduces a SAUF valve-integrated variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X1000N 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 SAU40X1000N 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 SU40X1000N Is Used
Long-Stroke Transfer
Pushes packages between conveyor lanes over a 1000mm distance using a safe 377 N working load.
Material Ejection
Ejects molded parts from a press area, using the adjustable 21mm cushions to brake at stroke end.
Replacing the Airtac SU32~50 Standard Cylinder SU40X1000N with the SAU40X1000N
To replace this discontinued SU40X1000N, order the SAU40X1000N, verifying your 1/4" port, M12x1.25 rod thread, and SC-series mounting hardware. Since this is a non-magnetic NBR-seal unit, it cannot hold a sensor; if sensing is now required, the SAU uses CMSG/DMSG/EMSG switches. At 1000mm stroke, prevent rod bending by using an external guide to absorb side loads. For sizing alternatives, a 32mm bore yields 402 N push at 0.5 MPa, while a 50mm bore offers 982 N. Note that air cushions only decelerate the piston; use an external rod lock or pilot-operated check valve to hold loads securely.
Replacement checklist
- ✓ Same bore / stroke → SAU40X1000N
- ✓ 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 SU40X1000N FAQ
Yes, the SU40X1000N is discontinued. The direct replacement is the SAU40X1000N, matching the 40mm bore, 1000mm stroke, 628 N force at 0.5 MPa, 1/4" port, and SC-series mounting.
It delivers 628 N push and 528 N pull at 0.5 MPa, 879 N at 0.7 MPa, and a 128 kgf max at 1.0 MPa. This non-magnetic SKU cannot take sensors, whereas the SAU replacement supports CMSG/DMSG/EMSG switches.
