This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X375, 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 SU50X375
The AirTAC Airtac SU32~50 Standard Cylinder SU50X375 is a double-acting profile-type standard cylinder with a Ø50mm bore and 375mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X375, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X375
The AirTAC SU50X375 is a discontinued double-acting profile-type cylinder with a 50mm bore and 375mm stroke. It delivers 982 N push force at 0.5 MPa through a 1/4 inch port. AirTAC replaced this unit with the SAU50X375, a direct alternative retaining the exact bore, stroke, force, and SC-series mounting footprint.
The SAU upgrade adopts current CMSG/DMSG/EMSG sensors, unlike this legacy unit which cannot accept a magnetic switch (no -S option). The SAU family also introduces the SAUF valve-integrated variant, an option the original SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X375 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X375 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 SU50X375 Is Used
Package Diverting
Pushes medium-weight cartons off a main belt line using the 982 N push force at 0.5 MPa, with the 375mm stroke clearing guide rails.
Pallet Positioning
Indexes empty pallets into a wrapping station, where the 50 kg vertical lift capacity handles light positioning tasks safely.
Gate Actuation
Opens and closes machine safety gates, requiring external guides to support the rod over the 375mm travel distance.
Replacing the Airtac SU32~50 Standard Cylinder SU50X375 with the SAU50X375
To replace the SU50X375, order the SAU50X375, confirming the 1/4 inch port, M16x1.5 rod thread, and SC-series mounting hardware. Because this 375mm stroke is long, use an external guide to prevent rod bending and side-load wear. For higher force needs, the neighbouring 63mm bore offers 1559 N push at 0.5 MPa; for lighter duties, the 40mm bore provides 628 N. Note that a plain cylinder drifts without live air—the cushion only decelerates—so add a pilot-operated check valve or external rod lock to hold loads. The SAUF variant with a built-in valve is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU50X375
- ✓ 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 SU50X375 FAQ
Yes, the AirTAC SU50X375 is discontinued. The direct replacement is the SAU50X375. It matches the 50mm bore, 375mm stroke, 982 N force, 1/4 inch port, and SC-series mounting accessories, so it fits the same application directly.
It delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf maximum at 1.0 MPa. This specific SKU lacks a magnet and cannot take a sensor; the SAU50X375 replacement supports CMSG/DMSG/EMSG switches.
