This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X160SN, 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 SU40X160SN
The AirTAC SU32~50 Standard Cylinder SU40X160SN 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 SAU40X160SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X160SN
The AirTAC SU40X160SN is a discontinued double-acting profile-type cylinder with a 40mm bore and 160mm stroke, delivering 628N push and 528N pull at 0.5MPa. Its extruded aluminum barrel is more compact than an ISO 15552 unit of the same bore. The direct replacement is the SAU40X160SN, matching the 1/4" port, M12x1.25 rod thread, force, and SC-series mounting.
This NBR-sealed unit operates at -20 to +70C. The SAU upgrade switches the -S magnet to CMSG/DMSG/EMSG sensors and adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X160SN 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 SAU40X160SN 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 SU40X160SN Is Used
Package Diverting
Actuates diverter arms on packaging lines, using the 160mm stroke to push cartons cleanly off the main belt at high cycle rates.
Pallet Stops
Controls low-profile pallet stops in compact material handling zones where the shorter profile body saves valuable floor space.
Clamp Actuation
Drives mid-force clamping fixtures for light machining, providing reliable 628N hold at 0.5MPa without external hydraulics.
Replacing the Airtac SU32~50 Standard Cylinder SU40X160SN with the SAU40X160SN
To replace this SU40X160SN, order the SAU40X160SN direct: it preserves the 40mm bore, 160mm stroke, 1/4" port, PT/G/NPT thread choice, and SC-series mounting. If sizing alternatives, the 32mm bore yields 402N push at 0.5MPa while the 50mm bore provides 982N. Because this 160mm stroke exceeds 300mm when scaling up designs, ensure adequate guide rails to prevent rod bending under side loads. Note the -S magnet switches from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. The cushion only decelerates; use an external rod lock or pilot-operated check valve to hold loads. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU40X160SN
- ✓ 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 SU40X160SN FAQ
Yes, the SU40X160SN is discontinued. The direct replacement is the SAU40X160SN. It shares the same 40mm bore, 160mm stroke, 1/4" port, output force, and SC-series mounting, but the -S magnet now requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 40mm bore features a 1/4" port and M12x1.25 rod thread. It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, 1130N at 0.9MPa, and a theoretical maximum of 128kgf at 1.0MPa. Operating speed is 30-800mm/s.
