This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X300SN, 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 SU50X300SN
The AirTAC SU32~50 Standard Cylinder SU50X300SN is a double-acting profile-type standard cylinder with a Ø50mm bore and 300mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X300SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X300SN
The AirTAC SU50X300SN is a discontinued double-acting profile-type cylinder with a 50mm bore and 300mm stroke. It delivers 982N push force at 0.5MPa via a 1/4 inch port. AirTAC replaced this unit with the SAU50X300SN, a direct alternative retaining the exact bore, stroke, force, port and SC-series mounting.
This unit includes a piston magnet (-S) for legacy CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The NBR seal (-N) suits -20 to +70C. The SAU line also adds a SAUF valve-integrated variant the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X300SN 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 SAU50X300SN 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 SU50X300SN Is Used
Package Diversion
Pushes 50kg cartons at 90 degrees on a sorting line using the 300mm stroke, relying on the 982N thrust at 0.5MPa.
Clamp Actuation
Extends 300mm to position workholding clamps on an assembly fixture, taking advantage of the compact profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU50X300SN with the SAU50X300SN
To replace this SU50X300SN, order the SAU50X300SN. Confirm the 1/4 inch port, M16x1.5 rod thread, and SC-series mounting accessories (LB/FA/FB/CA/CB) are reused. Because this has a -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For the 300mm stroke, use an external guide to prevent rod bending and side-load wear. If sizing down, a 40mm bore gives 628N push; sizing up, a 63mm bore yields 1559N. The air cushion only decelerates; for load holding on air loss, add an external rod lock or pilot-operated check valve. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X300SN
- ✓ 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 SU50X300SN FAQ
Yes, the SU50X300SN is discontinued. The direct replacement is the SAU50X300SN. It matches the 50mm bore, 300mm stroke, 982N force, 1/4 inch port and SC-series mounting. The only change is the sensor family: the SAU uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
The 50mm bore uses a 1/4 inch port with an M16x1.5 rod thread. At 0.5MPa it provides 982N push and 825N pull force. At 0.7MPa push is 1374N, and the theoretical maximum is 200kgf at 1.0MPa. Operating speed is 30-800mm/s.
