This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X885S, 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 SU50X885S
The AirTAC Airtac SU32~50 Standard Cylinder SU50X885S is a double-acting profile-type standard cylinder with a Ø50mm bore and 885mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X885S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X885S
The AirTAC SU50X885S is a discontinued double-acting profile-type cylinder with a 50mm bore and 885mm stroke. It delivers 982N push and 825N pull at 0.5MPa via a 1/4" port. AirTAC replaced this end-of-line unit with the SAU50X885S, a direct replacement retaining the exact bore, stroke, force, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to supersede the legacy CS1-B/DS1-B switches used on this -S magnet model, and adds an optional SAUF built-in 4M valve. Because the 885mm stroke exceeds 300mm, external guides are recommended to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X885S 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 SAU50X885S 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 SU50X885S Is Used
Long-Stroke Diversion
Pushes packages across transfer lines using the full 885mm travel, relying on the adjustable end cushions to decelerate the 50mm bore smoothly.
Automated Press Clamping
Secures workpieces during machining operations, utilizing the compact extruded aluminum profile to save space in tight cell layouts.
Replacing the Airtac SU32~50 Standard Cylinder SU50X885S with the SAU50X885S
To replace this SU50X885S with the SAU50X885S, verify the 50mm bore, 885mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. The -S piston magnet necessitates a sensor family change from CS1-B/DS1-B to CMSG/DMSG/EMSG. If you need higher force, the neighboring 63mm bore yields 1559N push at 0.5MPa; for lighter loads, the 40mm bore provides 628N. Note that a plain cylinder drifts on air loss, so fit an external rod lock for held loads. Finally, an 885mm stroke mandates external guides to absorb side-load and prevent rod bending. Consider the SAUF variant if you want a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X885S
- ✓ 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 SU50X885S FAQ
Yes, the SU50X885S is discontinued. The direct replacement is the AirTAC SAU50X885S. It matches the 50mm bore, 885mm stroke, 1/4" port, output force, and SC-series mounting accessories perfectly.
This double-acting cylinder delivers 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
