This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X50TC, 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 SU40X50TC
The AirTAC SU32~50 Standard Cylinder SU40X50TC is a double-acting profile-type standard cylinder with a Ø40mm bore and 50mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X50TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X50TC
The AirTAC SU40X50TC is a discontinued double-acting profile-type cylinder with a 40mm bore, 50mm stroke, and a 1/4" port. Delivering 628N push force at 0.5MPa, it uses an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same size. AirTAC replaced this unit with the SAU40X50TC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series TC mounting.
Because this specific SKU lacks a magnet, it cannot accept a position sensor. If sensing is required, the SAU replacement enables the current CMSG/DMSG/EMSG switch family (the SU line used legacy CS1-B/DS1-B). The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X50TC 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 SAU40X50TC 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 SU40X50TC Is Used
Package Diverting
Ideal for 50mm stroke diverting arms on packaging lines, providing 628N push at 0.5MPa to reliably redirect cartons without overshoot.
Gate Actuation
Actuates compact sorting gates using the TC mount, fitting neatly into existing frames with its shorter profile-type body.
Replacing the Airtac SU32~50 Standard Cylinder SU40X50TC with the SAU40X50TC
To replace the SU40X50TC, order the SAU40X50TC. Verify your 1/4" port thread (PT, G, or NPT) and the M12x1.25 rod-end thread. The TC mounting is an SC-series accessory that carries over directly. Since this SKU has no magnet (-S), it cannot hold a sensor; upgrading to an SAU-S model allows modern CMSG/DMSG/EMSG switches. For load holding, note that the air cushions only decelerate the piston at stroke end—a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve. If you need more force, the 50mm bore offers 982N push at 0.5MPa; if less is acceptable, the 32mm bore provides 402N. The SAUF valve-integrated option can simplify plumbing if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU40X50TC
- ✓ 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 SU40X50TC FAQ
Yes, the SU40X50TC is discontinued. The direct replacement is the SAU40X50TC. It shares the same 40mm bore, 50mm stroke, 1/4" port, output force, and SC-series TC mounting, so it bolts directly into the same application.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches if you order an -S version.
