This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X150H, 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 SU50X150H
The AirTAC SU32~50 Standard Cylinder SU50X150H is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X150H, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X150H
The AirTAC SU50X150H is a discontinued double-acting profile-type cylinder with a 50mm bore, 150mm stroke, and Viton H high-temperature seals rated for 0-150 C. Delivering 982 N push force at 0.5 MPa through a 1/4" port, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. The direct replacement is the SAU50X150H, matching the body, stroke, force, port, and SC-series mounting.
Because this SKU lacks a magnet (-S), it cannot accept position sensors. The SAU upgrade supports modern CMSG/DMSG/EMSG switches and introduces the SAUF built-in 4M solenoid valve variant, which the SU line never offered.

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 SAU50X150H 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 SU50X150H Is Used
Hot End Ejection
Ideal for pushing molded components in high-temperature zones up to 150 C, utilizing the Viton H seals and 982 N thrust at 0.5 MPa for reliable operation.
Heated Product Diverting
Sorts or deflects warm goods along a processing line where a 150mm stroke and compact profile body provide precise movement without excessive footprint.
Replacing the Airtac SU32~50 Standard Cylinder SU50X150H with the SAU50X150H
To replace the SU50X150H, order the SAU50X150H ensuring the 1/4" port, M16x1.5 rod thread, and SC-series mounting hardware match. If stepping up, the 63mm bore yields 1559 N push at 0.5 MPa; stepping down to 40mm provides 628 N. This Viton H model handles 0-150 C environments. Since this non-magnetic SKU cannot take sensors, if detection is needed on the SAU you must add the -S option and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. The 150mm stroke requires attention to side-load alignment; use a guide to prevent rod bending. Note that air cushions only decelerate the piston—they do not hold loads. For static holding during air loss, install an external rod lock or pilot-operated check valve. For faster cycling, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X150H
- ✓ 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 SU50X150H FAQ
Yes, the SU50X150H is discontinued. The direct replacement is the SAU50X150H. It shares the exact same 50mm bore, 150mm stroke, 1/4" port, Viton H high-temp seals, and SC-series mounting, allowing a seamless physical swap.
At 0.5 MPa it provides 982 N push and 825 N pull force, reaching 1374 N push at 0.7 MPa, with a theoretical maximum of 200 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept position switches; the SAU replacement with the -S option uses CMSG/DMSG/EMSG sensors.
