This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X300SH, 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 SU50X300SH
The AirTAC SU32~50 Standard Cylinder SU50X300SH 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 SAU50X300SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X300SH
The AirTAC SU50X300SH is a discontinued double-acting profile cylinder with a 50mm bore, 300mm stroke, and a high-temp Viton H seal rated for 0-150 C. Delivering 982 N push at 0.5 MPa, it uses a compact extruded aluminum body that is shorter than an ISO 15552 cylinder of the same bore. The direct replacement is the SAU50X300SH, matching the 1/4" port, M16x1.5 rod thread, and SC-series mounting.
When upgrading to the SAU50X300SH, the body, bore, stroke, and force remain identical. Two key changes apply: the SAU adds an optional SAUF variant with a built-in 4M solenoid valve the SU lacked, and the -S magnet switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X300SH 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 SAU50X300SH 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 SU50X300SH Is Used
Hot Product Diversion
Uses the 982 N push force and 300mm reach to push heated packaged goods across transfer plates, leveraging the Viton H seal for ambient thermal resilience.
Vertical Pallet Lifts
Raises 50 kg loads through a 300mm vertical stroke, requiring an external guide to prevent rod bending on the long 50mm bore profile body.
Press Ejection Systems
Ejects molded parts from warm zones using the 825 N pull force at 0.5 MPa, relying on adjustable end cushions to decelerate fast ejection moves.
Replacing the Airtac SU32~50 Standard Cylinder SU50X300SH with the SAU50X300SH
To replace the SU50X300SH, order the SAU50X300SH direct equivalent, verifying the 50mm bore, 300mm stroke, 1/4" port, and high-temp Viton H seal. Because this SKU has a magnet (-S), you must upgrade your switches: the legacy CS1-B/DS1-B sensors are replaced by the CMSG/DMSG/EMSG family on the SAU. For load handling, note that a plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for holding. At 300mm stroke, prevent rod bending by guiding the load externally to avoid side-load forces. If downsizing, a 40mm bore yields 628 N push; if upsizing, a 63mm bore provides 1559 N. The SAUF valve-integrated option can simplify plumbing if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU50X300SH
- ✓ 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 SU50X300SH FAQ
Yes, the AirTAC SU50X300SH is discontinued. The direct replacement is the SAU50X300SH. It provides identical bore, stroke, output force, 1/4" port, and SC-series mounting compatibility, while adding the SAUF built-in-valve option.
The 50mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf max at 1.0 MPa. Because this model includes a magnet (-S), upgrading to the SAU requires changing legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
