This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X213S, 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 SU50X213S
The AirTAC SU32~50 Standard Cylinder SU50X213S is a double-acting profile-type standard cylinder with a Ø50mm bore and 213mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X213S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X213S
The AirTAC SU50X213S is a discontinued double-acting profile cylinder with a 50mm bore and 213mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. The direct replacement is the SAU50X213S, matching the body, stroke, force, port and SC-series mounts.
This 213mm stroke is nonstandard (standard intervals are 200mm and 250mm). The -S suffix means a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X213S 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 SAU50X213S 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 SU50X213S Is Used
Package Diverting
Pushes cartons at 90 degrees on a sorting line using the 982N push force at 0.5 MPa, with the 213mm stroke clearing the belt width.
Pallet Stop Gate
Acts as a pneumatic stop for lightweight pallets, where the 50kg vertical lift capacity handles gravity-fed buffer queues safely.
Component Clamping
Secures aluminum housings for machining operations, taking advantage of the compact profile body to save space in tight fixtures.
Replacing the Airtac SU32~50 Standard Cylinder SU50X213S with the SAU50X213S
To replace this discontinued SU50X213S, order the SAU50X213S. Confirm the 1/4" port, M16x1.5 rod thread, PT/G/NPT thread choice, and SC-series mounting. Because it has -S, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If sizing down, a 40mm bore gives 628N push; if sizing up, a 63mm bore yields 1559N. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. With a 213mm stroke, ensure guide rails prevent rod bending under side loads. If you need self-switching, explore the SAUF variant with its built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X213S
- ✓ 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 SU50X213S FAQ
Yes, the SU50X213S is end-of-life. The direct replacement is the SAU50X213S. It matches the 50mm bore, 213mm stroke, 1/4" port, output force and SC-series mounting accessories. You simply order the SAU equivalent.
It provides 982N push and 825N pull at 0.5 MPa, 1374N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must switch to CMSG/DMSG/EMSG sensors.
