This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X190S, 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 SU40X190S
The AirTAC SU32~50 Standard Cylinder SU40X190S is a double-acting profile-type standard cylinder with a Ø40mm bore and 190mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X190S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X190S
The AirTAC SU40X190S is a discontinued double-acting profile-type cylinder with a 40mm bore and 190mm stroke. It delivers 628N push force at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU40X190S, a direct alternative retaining the exact bore, stroke, force, port and SC-series mounting.
The extruded aluminium body is more compact than an ISO 15552 equivalent. Note the -S magnet used legacy CS1-B/DS1-B switches; the SAU successor uses CMSG/DMSG/EMSG sensors and adds a SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X190S 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 SAU40X190S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 40 | Bore size in mm. |
| ×190 | 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 SU40X190S Is Used
Component Clamping
Secures medium workpieces during machining, using the 628N push force to hold parts firmly against a fixture stop.
Package Diverting
Extends 190mm to push cartons off a main conveyor belt, with the compact profile saving valuable machine space.
Pallet Stopper Gate
Acts as a pneumatic stop gate on low-friction roller conveyors, handling loads safely up to the 32kg vertical limit.
Replacing the Airtac SU32~50 Standard Cylinder SU40X190S with the SAU40X190S
To replace this SU40X190S, order the SAU40X190S. Verify your 1/4" port, M12x1.25 rod thread, and SC-series mounting. Because this SKU has the -S magnet, plan to upgrade from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. If sizing alternatives, a 32mm bore yields 402N push at 0.5MPa, while a 50mm bore provides 982N. For loads needing 190mm travel, ensure guidance to prevent rod bending. A plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for secure holding. The SAUF variant offers a built-in 4M solenoid valve if self-switching is desired.
Replacement checklist
- ✓ Same bore / stroke → SAU40X190S
- ✓ 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 SU40X190S FAQ
Yes, the SU40X190S is discontinued. The direct replacement is the AirTAC SAU40X190S. It shares the identical 40mm bore, 190mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it fits the same application directly.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must use the current CMSG/DMSG/EMSG sensor family.
