This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X72S, 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 SU50X72S
The AirTAC SU32~50 Standard Cylinder SU50X72S is a double-acting profile-type standard cylinder with a Ø50mm bore and 72mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X72S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X72S
The AirTAC SU50X72S is a discontinued double-acting profile-type cylinder with a 50mm bore and 72mm stroke. Delivering 982N push force at 0.5MPa via a 1/4" port, its extruded aluminum body is more compact than an ISO 15552 unit. AirTAC's direct replacement is the SAU50X72S, matching the exact bore, stroke, force, and SC-series mounts.
The SAU upgrade switches the -S magnet from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors, and introduces the SAUF valve-integrated option the SU lacked. Note that air cushions only decelerate; use a rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X72S 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 SAU50X72S 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 SU50X72S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×72 | 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 SU50X72S Is Used
Clamp Actuation
Provides 982N push force at 0.5MPa for securing mid-weight workpieces during CNC machining or welding operations.
Package Diverting
Uses the 72mm stroke to push cartons off a main conveyor belt line, handling the 50kg vertical lift capacity easily.
Gate Positioning
Drives short-throw sorting gates in distribution centers, relying on the compact profile body to fit tight spaces.
Replacing the Airtac SU32~50 Standard Cylinder SU50X72S with the SAU50X72S
To replace the SU50X72S, order the SAU50X72S direct equivalent, verifying the 1/4" port, M16x1.5 rod thread, and SC-series mounting hardware. Because this SKU includes the -S magnet, you must upgrade your switches: the legacy CS1-B/DS1-B sensors are replaced by CMSG/DMSG/EMSG on the SAU. If dropping down to a 40mm bore yields 628N (insufficient), stepping up to a 63mm bore provides 1559N. For load holding on air loss, add an external rod lock, as cushions only decelerate. The SAUF variant offers a built-in valve if needed. At 72mm stroke, side-load risks are low, but ensure front mounting alignment.
Replacement checklist
- ✓ Same bore / stroke → SAU50X72S
- ✓ 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 SU50X72S FAQ
Yes, the AirTAC SU50X72S is discontinued and end-of-life. The direct replacement is the SAU50X72S. It shares the same 50mm bore, 72mm stroke, 1/4" port, output force, and SC-series mounting accessories, fitting the exact same application.
The 50mm bore provides 982N push and 825N pull at 0.5MPa, 1374N at 0.7MPa, and a 200kgf max at 1.0MPa. Because this is an -S magnet model, the old CS1-B/DS1-B switches do not fit the SAU replacement; you must use CMSG/DMSG/EMSG sensors.
