This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X100H, 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 SU40X100H
The AirTAC SU32~50 Standard Cylinder SU40X100H 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 SAU40X100H, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X100H
The AirTAC SU40X100H 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, and the direct replacement is the SAU40X100H. This high-temp Viton H seal variant operates from 0 to 150C, whereas standard cylinders stop at 70C. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore, reusing AirTAC SC-series mounts. This specific SKU lacks a magnet, so it cannot accept a magnetic sensor. The SAU upgrade introduces the SAUF built-in 4M valve option, which the SU line never offered.
The 1/4 inch port and M12x1.25 rod thread carry over identically. Because this is a non-magnetic SKU, if you previously used legacy CS1-B or DS1-B switches, note that the SAU replacement requires current CMSG, DMSG, or EMSG sensors on its -S variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X100H 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 SAU40X100H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×100 | Stroke length in mm. |
| -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 SU40X100H Is Used
Hot Stamp Ejection
Uses the Viton H high-temperature seal to survive 150C ambient heat near heated platens while pushing lightweight stamped parts off a fixture.
Divert Gate Actuation
Provides 628N push at 0.5MPa to pivot a sorting gate on a packaging line, safely within the 377N working load for continuous daily cycling.
Pallet Stopper Arm
Acts as a 100mm stroke stop for 32kg pallet loads on a gravity conveyor, relying on the compact profile body to fit tight vertical spaces.
Replacing the Airtac SU32~50 Standard Cylinder SU40X100H with the SAU40X100H
To replace this discontinued SU40X100H, order the SAU40X100H, which matches the 40mm bore, 100mm stroke, 1/4 inch port, M12x1.25 rod thread, and SC-series mounting. This SKU has no magnet (-S) and therefore cannot support a sensor; if sensing is needed on the new unit, specify an SAU40X100HS and migrate to CMSG, DMSG, or EMSG switches. The Viton H seal provides 0-150C heat resistance. If your force needs are lower, a 32mm bore gives 402N push at 0.5MPa; for higher loads, a 50mm bore yields 982N. Remember that a plain cylinder drifts without live air—the cushion only decelerates near stroke end—so fit an external rod lock or pilot-operated check valve for secure load holding. For self-switching without external plumbing, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU40X100H
- ✓ 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 SU40X100H FAQ
Yes, the SU40X100H is discontinued. The direct replacement is the SAU40X100H. It provides identical bore, stroke, output force, 1/4 inch port, and SC-series mounting compatibility, meaning it fits the same application directly.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, 1130N at 0.9MPa, and a theoretical max of 128kgf at 1.0MPa. A plain cylinder does not hold a load without live air—the cushion only decelerates—so use an external rod lock for holding.
