This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X80TC, 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 SU40X80TC
The AirTAC Airtac SU32~50 Standard Cylinder SU40X80TC is a double-acting profile-type standard cylinder with a Ø40mm bore and 80mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X80TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X80TC
The AirTAC SU40X80TC is a discontinued double-acting profile-type cylinder with an 80 mm stroke and 40 mm bore. It delivers 628 N push and 528 N pull at 0.5 MPa via a 1/4" port. AirTAC replaced this unit with the SAU40X80TC, a direct upgrade retaining the exact bore, stroke, force, port and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU replacement adds modern CMSG/DMSG/EMSG switch compatibility and a new SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X80TC 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 SAU40X80TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 SU40X80TC Is Used
Package Diversion
Pushes lightweight cartons off a belt line using 628 N at 0.5 MPa, with the 80 mm stroke providing precise lateral transfer.
Pallet Stop Gate
Acts as a compact TC-mounted stopper for low-profile pallets, leveraging the shorter profile body to fit tight conveyor frames.
Clamp Actuation
Secures small aluminium parts for machining, applying a safe 377 N working load without deforming the workpiece.
Replacing the Airtac SU32~50 Standard Cylinder SU40X80TC with the SAU40X80TC
To replace this discontinued SU40X80TC, order the SAU40X80TC direct equivalent, verifying the 1/4" port, M12x1.25 rod thread and TC mounting. Since this specific SKU has no magnet, it cannot support sensing; if detection is needed, an SAU -S variant uses CMSG/DMSG/EMSG switches. Sizing both ways: a 32 mm bore offers 402 N push at 0.5 MPa, while a 50 mm bore provides 982 N. Note that a plain cylinder drifts on air loss—the 21 mm cushions only decelerate the stroke end, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU40X80TC
- ✓ 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 SU40X80TC FAQ
Yes, the SU40X80TC is discontinued. The direct replacement is the AirTAC SAU40X80TC, which shares the same 40 mm bore, 80 mm stroke, 1/4" port, output force and TC mounting. You simply order the SAU equivalent.
It provides 628 N push and 528 N pull at 0.5 MPa, 879 N at 0.7 MPa, 1130 N at 0.9 MPa, and a 128 kgf max at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot take a sensor; the SAU -S variant supports CMSG/DMSG/EMSG switches.
