This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X100SH, 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 SU40X100SH
The AirTAC SU32~50 Standard Cylinder SU40X100SH is a double-acting profile-type standard cylinder with a Ø40mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X100SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X100SH
The AirTAC SU40X100SH is a discontinued double-acting profile-type cylinder with a 40mm bore and 100mm stroke. It delivers 628N push and 528N pull at 0.5MPa, using a 1/4" port and M12x1.25 rod thread. The direct replacement is the SAU40X100SH, matching the bore, stroke, output force, port, and SC-series mounting.
This unit includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The H seal provides 0-150C Viton high-temp resistance. The SAU also adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X100SH 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 SAU40X100SH 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 SU40X100SH Is Used
Hot End Ejection
Uses the Viton -H seal for 0-150C environments, providing 628N push at 0.5MPa to eject small molded parts safely.
Transfer Diverters
Delivers 528N pull force to actuate routing gates on 100mm strokes, matching existing SC-series mounting brackets.
Replacing the Airtac SU32~50 Standard Cylinder SU40X100SH with the SAU40X100SH
To replace this SU40X100SH, order the SAU40X100SH, confirming the 40mm bore, 100mm stroke, 1/4" port, M12x1.25 thread, and SC-series mounting. Because the -S magnet is present, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. The -H Viton seal handles 0-150C; if you need self-switching, explore the SAUF built-in-valve variant. Sizing both ways: a 32mm bore offers 402N [email protected], while a 50mm bore gives 982N. For load holding, a plain cylinder drifts without live air—use an external rod lock or pilot-operated check valve, as cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAU40X100SH
- ✓ 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 SU40X100SH FAQ
Yes, the SU40X100SH is discontinued. The direct replacement is the SAU40X100SH. It shares the same 40mm bore, 100mm stroke, 628N force at 0.5MPa, 1/4" port, and SC-series mounting.
It pushes 628N and pulls 528N at 0.5MPa, 879N at 0.7MPa, with a 128kgf max at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
