This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X50SN, 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 SU50X50SN
The AirTAC SU32~50 Standard Cylinder SU50X50SN is a double-acting profile-type standard cylinder with a Ø50mm bore and 50mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X50SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X50SN
The AirTAC SU50X50SN is a discontinued double-acting profile-type cylinder with a 50mm bore and 50mm stroke. Built with an extruded aluminum barrel, it is shorter and more compact than an ISO 15552 cylinder of the same bore. It delivers 982 N push force at 0.5 MPa and uses a 1/4" port. The direct replacement is the SAU50X50SN, which matches the original bore, stroke, output force, port size, and SC-series mounting.
When upgrading to the SAU equivalent, the body and mechanics remain identical, but the legacy CS1-B/DS1-B sensors used on this -S magnet model are replaced by the current CMSG/DMSG/EMSG switch family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered. The -N seal denotes NBR rubber, operating reliably from -20 to +70 C.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X50SN 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 SAU50X50SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 50 | Bore size in mm. |
| ×50 | Stroke length in mm. |
| -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 SU50X50SN Is Used
Component Clamping
Secures mid-weight machined parts during milling or drilling, utilizing the 982 N push force at 0.5 MPa for rigid workholding.
Package Diverting
Actuates sorting pop-up arms on packaging lines, where the 50 kg vertical lift capacity easily manages boxed goods routing.
Pallet Stop Gates
Controls pallet flow on roller conveyors by raising and lowering stop gates, benefiting from the compact profile body design.
Replacing the Airtac SU32~50 Standard Cylinder SU50X50SN with the SAU50X50SN
To replace the discontinued SU50X50SN, order the SAU50X50SN direct equivalent, confirming the 50mm bore, 50mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting hardware. Because this SKU includes the -S magnet, you must switch from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. If your application requires integrated flow control, explore the SAUF variant which features a built-in 4M solenoid valve. For sizing alternatives, the neighboring 40mm bore yields 628 N push at 0.5 MPa, while the 63mm bore provides 1559 N. Remember that a plain cylinder does not hold load without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X50SN
- ✓ 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 SU50X50SN FAQ
Yes, the SU50X50SN is discontinued. The direct replacement is the SAU50X50SN. It shares the same 50mm bore, 50mm stroke, 1/4" port, output force, and SC-series mounting accessories, allowing a direct physical swap.
The 50mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors on the new SAU unit.
