This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X100, 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 SU40X100
The AirTAC Airtac SU32~50 Standard Cylinder SU40X100 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 SAU40X100, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X100
The AirTAC SU40X100 is a discontinued double-acting profile-type cylinder, delivering 628 N push force at 0.5 MPa through a 40 mm bore and 100 mm stroke. AirTAC replaced it with the SAU40X100 direct replacement, preserving the exact 1/4" port, M12x1.25 rod thread, and SC-series mounting compatibility.
Because this SKU lacks a magnet, it cannot accept a sensor; the SAU upgrade enables CMSG/DMSG/EMSG switches on -S variants. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X100 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 SAU40X100 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 SU40X100 Is Used
Package Diverting
Provides reliable 100 mm stroke actuation to divert small cartons on a packaging line at up to 800 mm/s.
Stopper Gate Control
Acts as a compact pneumatic stopper for material handling pallets, fitting neatly into SC-series brackets.
Replacing the Airtac SU32~50 Standard Cylinder SU40X100 with the SAU40X100
To replace this discontinued SU40X100, order the SAU40X100 direct equivalent, matching the 40 mm bore, 100 mm stroke, 1/4" port, and SC-series mounting. If you need position sensing, specify an -S magnet on the SAU and migrate from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. This non-magnetic SKU cannot take a sensor. For higher loads, the 50 mm bore offers 982 N push at 0.5 MPa, while the 32 mm bore provides 402 N. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for held loads. The SAUF variant adds a built-in 4M solenoid valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU40X100
- ✓ 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 SU40X100 FAQ
Yes, the SU40X100 is discontinued. The direct replacement is the AirTAC SAU40X100, offering identical 40 mm bore, 100 mm stroke, 628 N force at 0.5 MPa, 1/4" port, and SC-series mounting compatibility.
The 40 mm bore features a 1/4" port. It delivers 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, 1130 N push at 0.9 MPa, and a theoretical maximum of 128 kgf at 1.0 MPa. This non-magnetic SKU cannot accept a sensor.
