This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X65, 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 SU50X65
The AirTAC Airtac SU32~50 Standard Cylinder SU50X65 is a double-acting profile-type standard cylinder with a Ø50mm bore and 65mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X65, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X65
The AirTAC SU50X65 is a discontinued double-acting profile-type cylinder with a 50mm bore and 65mm stroke. It delivers 982N push force at 0.5MPa via a 1/4 inch port. AirTAC replaced this unit with the SAU50X65, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting compatibility.
Because this is a non-magnet SKU, it cannot accept a sensor. If sensing is needed, the SAU replacement requires the current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X65 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 SAU50X65 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 SU50X65 Is Used
Clamping Mechanisms
Ideal for mid-tier clamping tasks requiring a 65mm stroke, delivering a safe 589N working load to secure workpieces during machining operations.
Package Diverting
Provides reliable actuation for diverting medium-weight packages on a production line, utilizing the compact profile body to save valuable machine space.
Replacing the Airtac SU32~50 Standard Cylinder SU50X65 with the SAU50X65
To replace the SU50X65, order the SAU50X65 and confirm your 1/4 inch port thread (PT, G, or NPT) plus the M16x1.5 rod-end and SC-series mounting hardware. This non-magnet SKU cannot support a switch; if you need position sensing, specify an SAU50X65S and migrate to CMSG/DMSG/EMSG sensors. For higher loads, the 63mm bore yields 1559N push at 0.5MPa; for lighter duty, the 40mm bore yields 628N. Note that a plain cylinder drifts on air loss—the 21mm cushions only decelerate—so add an external rod lock for held loads. The SAUF variant adds a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU50X65
- ✓ 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 SU50X65 FAQ
Yes, the AirTAC SU50X65 is discontinued. The direct replacement is the SAU50X65. It shares the identical 50mm bore, 65mm stroke, 982N force, 1/4 inch port, and SC-series mounting, so it fits the same application without modifications.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. The 21mm cushions only decelerate the piston near stroke end; a plain cylinder cannot hold a load on air loss, so use an external rod lock for vertical holding.
