This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X350SH, 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 SU50X350SH
The AirTAC SU32~50 Standard Cylinder SU50X350SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 350mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X350SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X350SH
The AirTAC SU50X350SH is a discontinued double-acting profile cylinder with a 50mm bore, 350mm stroke, and Viton H high-temperature seals (0-150 C). Delivering 982 N push force at 0.5 MPa, its direct replacement is the SAU50X350SH. This upgrade preserves the original 1/4" port, M16x1.5 rod thread, and SC-series mounting, meaning no mechanical changes are needed for your machine. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.
Because the -S magnet is present, this legacy unit used CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line lacked. Note that the air cushion only decelerates the piston; it does not hold the load if air pressure drops.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X350SH 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 SAU50X350SH produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU50X350SH
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×350 | 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 SU50X350SH Is Used
Hot End Diverting
Ideal for routing 50 kg workpieces on high-temperature packaging lines where the Viton H seal survives 150 C ambient heat.
Extended Reach Pressing
Provides 982 N of push force over a 350mm travel for assembling components located deep inside machinery frames.
Replacing the Airtac SU32~50 Standard Cylinder SU50X350SH with the SAU50X350SH
To replace this SU50X350SH, order the SAU50X350SH direct equivalent, confirming the 50mm bore, 350mm stroke, 1/4" port, and PT/G/NPT thread choice. The -S magnet means you must switch out legacy CS1-B/DS1-B switches for modern CMSG/DMSG/EMSG sensors. If you need integrated airflow control, explore the SAUF valve-integrated variant. For sizing alternatives, a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore provides 1559 N. At 350mm stroke, prevent rod bending by guiding the load externally to avoid side-load stress. A plain cylinder drifts without live air; for load holding, install an external rod lock or pilot-operated check valve, as the cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAU50X350SH
- ✓ 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 SU50X350SH FAQ
Yes, the SU50X350SH is discontinued. The direct replacement is the SAU50X350SH. It matches the 50mm bore, 350mm stroke, 1/4" port, output force, and SC-series mounting, but requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
The 50mm bore features a 1/4" air port. At 0.5 MPa it provides 982 N push and 825 N pull force. At 0.7 MPa push is 1374 N, and at 0.9 MPa it is 1767 N. The theoretical maximum force is 200 kgf at 1.0 MPa.
