This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X113S, 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 SU40X113S
The AirTAC SU32~50 Standard Cylinder SU40X113S is a double-acting profile-type standard cylinder with a Ø40mm bore and 113mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X113S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X113S
The AirTAC SU40X113S is a discontinued double-acting profile cylinder with a 40mm bore and 113mm stroke. It delivers 628N push force at 0.5MPa via a 1/4 inch port. AirTAC replaced this legacy unit with the SAU40X113S, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
The extruded aluminum profile body is more compact than an ISO 15552 cylinder of the same bore. Because this SKU includes a magnet (-S), it originally used CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X113S 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 SAU40X113S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU40X113S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×113 | 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 SU40X113S Is Used
Small Part Ejection
Provides 628N of push force at 0.5MPa to reliably eject machined small components from a fixture.
Package Diverting
Uses the 113mm stroke to push light packages off a main conveyor belt line onto a sorting branch.
Pallet Stopper Gate
Acts as a compact profile-body stopper gate for low-profile pallets moving through an assembly cell.
Replacing the Airtac SU32~50 Standard Cylinder SU40X113S with the SAU40X113S
To replace this discontinued SU40X113S, order the SAU40X113S. Verify your 1/4 inch port thread (PT, G, or NPT) and M12x1.25 rod-end thread. The 113mm stroke is a non-standard length but falls well under the 1200mm maximum, so it is fully supported. If downsizing to a 32mm bore, note the thrust drops to 402N at 0.5MPa; upsizing to a 50mm bore increases thrust to 982N. The -S magnet means you must migrate from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. A plain cylinder drifts without live air, as the 21mm adjustable cushions only decelerate near stroke end; use an external rod lock or pilot-operated check valve for secure load holding. For applications needing integrated control, explore the SAUF valve-cylinder variant.
Replacement checklist
- ✓ Same bore / stroke → SAU40X113S
- ✓ 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 SU40X113S FAQ
Yes, the SU40X113S is discontinued. The direct replacement is the SAU40X113S. It shares the identical 40mm bore, 113mm stroke, 1/4 inch port, output force, and SC-series mounting accessories, so it fits the same application without mechanical modifications.
At 0.5MPa it provides 628N push and 528N pull force, 879N push at 0.7MPa, 1130N push at 0.9MPa, and a maximum theoretical force of 128kgf at 1.0MPa. Because this is an -S magnet model, the original CS1-B/DS1-B switches are obsolete; the SAU replacement requires CMSG/DMSG/EMSG sensors.
