This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X175TC, 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 SU40X175TC
The AirTAC SU32~50 Standard Cylinder SU40X175TC is a double-acting profile-type standard cylinder with a Ø40mm bore and 175mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X175TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X175TC
The AirTAC SU40X175TC is a discontinued double-acting profile-type cylinder with a 40mm bore and 175mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore and delivers 628 N push force at 0.5 MPa. The direct replacement is the SAU40X175TC, matching the bore, stroke, 1/4" port, and SC-series TC mounting.
Because this non-magnetic SKU lacks a sensor groove switch, it cannot take a magnetic piston sensor. The SAU upgrade also introduces the SAUF built-in 4M solenoid valve option, which the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X175TC 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 SAU40X175TC 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 SU40X175TC Is Used
Package Diverting
Uses the 175mm stroke and 628 N push force at 0.5 MPa to push cartons cleanly off a main belt line via the TC mount.
Pallet Stopper Gate
Acts as a compact profile-body stopper for lightweight pallets, handling a safe 377 N working load without external tie-rods.
Component Clamping
Secures 32 kg vertical workpieces during machining, relying on the 40mm bore's 528 N pull force and adjustable cushions.
Replacing the Airtac SU32~50 Standard Cylinder SU40X175TC with the SAU40X175TC
To replace this discontinued SU40X175TC, order the SAU40X175TC. Verify your 1/4" port (default PT thread), M12x1.25 rod end, and the SC-series TC mounting interface, which all carry over directly. If downsizing, a 32mm bore yields 402 N push at 0.5 MPa; if upsizing, a 50mm bore provides 982 N. This non-magnetic SKU cannot accept a sensor, but if you ever need position detection on the SAU, you must add the -S option and use CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B). A plain cylinder drifts on air loss—the 21mm cushions only decelerate near stroke end—so add an external rod lock or pilot-operated check valve for load holding. For high-temperature environments up to 150 C, select the Viton H seal option.
Replacement checklist
- ✓ Same bore / stroke → SAU40X175TC
- ✓ 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 SU40X175TC FAQ
Yes, the AirTAC SU40X175TC is discontinued. The direct replacement is the SAU40X175TC. It matches the 40mm bore, 175mm stroke, 628 N force, 1/4" port, and SC-series TC mounting accessories perfectly.
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa it pushes 879 N, and the theoretical max is 128 kgf at 1.0 MPa. This specific SKU is non-magnetic and cannot take a sensor. If sensing is needed on the SAU replacement, add the -S option, which uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
