This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X190, 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 SU50X190
The AirTAC Airtac SU32~50 Standard Cylinder SU50X190 is a double-acting profile-type standard cylinder with a Ø50mm bore and 190mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X190, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X190
The AirTAC SU50X190 is a discontinued double-acting profile-type cylinder with a 50mm bore and 190mm stroke. Delivering 982N push force at 0.5MPa via a 1/4" port, its extruded aluminum barrel is more compact than an ISO 15552 unit of the same bore. AirTAC replaced this EOL unit with the SAU50X190, a direct replacement retaining the exact body, force, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade adds current CMSG/DMSG/EMSG switch compatibility for -S variants and introduces the SAUF built-in-valve option. Note that standard cushions only decelerate; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X190 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 SAU50X190 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 SU50X190 Is Used
Package Diverting
Actuates diverting arms on packaging lines, utilizing the 982N push force to redirect cartons efficiently.
Pallet Stopping
Serves as a pneumatic stop gate for lightweight pallets, benefiting from the compact profile body.
Clamp Actuation
Drives mid-force clamping fixtures for machining, providing reliable 50kg vertical lift holding dynamics.
Replacing the Airtac SU32~50 Standard Cylinder SU50X190 with the SAU50X190
To replace the SU50X190, order the SAU50X190, verifying the 50mm bore, 190mm stroke, 1/4" port, and M16x1.5 rod thread. This non-magnetic SKU cannot take a switch; if sensing is needed, specify an SAU50X190S and migrate from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For force context, the 50mm bore yields 982N push at 0.5MPa (safe load ~589N), while the neighboring 63mm bore provides 1559N. At 190mm stroke, side-load risks are low, but always guide the load to prevent rod bending. The cylinder will not hold load without air; add a pilot-operated check valve if needed. The SAUF valve-integrated variant is available if you want to simplify piping.
Replacement checklist
- ✓ Same bore / stroke → SAU50X190
- ✓ 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 SU50X190 FAQ
Yes, the SU50X190 is discontinued. The direct replacement is the AirTAC SAU50X190. It matches the original 50mm bore, 190mm stroke, 982N force, 1/4" port, and SC-series mounting accessories, but uses current CMSG/DMSG/EMSG sensors for magnetic variants.
The 50mm bore delivers 982N push and 825N pull at 0.5MPa, 1374N at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. Because this specific SKU lacks a magnet (-S), it cannot accept a sensor; you must order a magnetic version to use switches.
