This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X170H, 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 SU40X170H
The AirTAC SU32~50 Standard Cylinder SU40X170H is a double-acting profile-type standard cylinder with a Ø40mm bore and 170mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X170H, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X170H
The AirTAC SU40X170H is a discontinued double-acting profile cylinder with a 40mm bore and 170mm stroke. Featuring a high-temperature Viton H seal, it handles 0 to 150 C environments and delivers 628 N push at 0.5 MPa. The direct replacement is the SAU40X170H, matching the 1/4" port, M12x1.25 rod, and SC-series mounting.
This extruded aluminum body is shorter than ISO 15552 equivalents. Being a no-magnet SKU, it cannot take sensors. The SAU upgrade adds CMSG/DMSG/EMSG switch compatibility and an optional SAUF built-in valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X170H 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 SAU40X170H 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 SU40X170H Is Used
Hot End Ejection
Ideal for pushing parts at elevated temperatures using the Viton H seal, delivering 628 N push force for reliable ejection.
170mm Transfer Gate
Actuates sorting gates with a compact 170mm stroke, handling the 32 kg vertical load margin safely.
Compact Clamping Station
Clamps workpieces in tight spaces where the shorter profile body saves space without sacrificing 1/4" port flow.
Replacing the Airtac SU32~50 Standard Cylinder SU40X170H with the SAU40X170H
To replace this SU40X170H, order the SAU40X170H direct equivalent, verifying the 1/4" port, M12x1.25 thread, and SC-series mounting. Because this is a no-S SKU, it cannot accept magnetic sensors; if sensing is required, you must select an SAU model with the -S option and use CMSG/DMSG/EMSG switches. For load holding, note that standard cylinders drift on air loss—the 21mm cushions only decelerate—so add an external rod lock or pilot check valve. The 170mm stroke is under the 1200mm max, avoiding rod-bending issues. If sizing up or down, a 32mm bore yields 402 N push, while a 50mm bore yields 982 N at 0.5 MPa.
Replacement checklist
- ✓ Same bore / stroke → SAU40X170H
- ✓ 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 SU40X170H FAQ
Yes, the SU40X170H is discontinued. The direct replacement is the SAU40X170H, offering the same 40mm bore, 170mm stroke, 628 N push at 0.5 MPa, 1/4" port, and SC-series mounting compatibility.
It delivers 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a max of 128 kgf at 1.0 MPa. Because this SKU lacks a magnet, it cannot take sensors; the SAU replacement with -S uses CMSG/DMSG/EMSG switches.
