This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X10, 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 SU50X10
The AirTAC Airtac SU32~50 Standard Cylinder SU50X10 is a double-acting profile-type standard cylinder with a Ø50mm bore and 10mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X10, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X10
The AirTAC SU50X10 is a discontinued double-acting profile-type cylinder with a 50 mm bore and 10 mm stroke. Delivering 982 N push force at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. AirTAC replaced this EOL model with the SAU50X10, a direct upgrade retaining the exact bore, stroke, output force, 1/4 inch port, and SC-series mounting footprint.
The SAU replacement introduces modern CMSG/DMSG/EMSG sensors, superseding the legacy CS1-B/DS1-B switches, and adds an optional SAUF built-in 4M valve the original SU lacked. Note this specific SKU lacks a magnet, so it cannot accept a position switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X10 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 SAU50X10 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 SU50X10 Is Used
Short-Stroke Clamping
Ideal for holding aluminum extrusions or sheet metal parts during CNC machining using the 982 N push force over the 10 mm travel.
Package Diverting
Provides rapid 10 mm actuation to push small cartons off a packaging line, operating efficiently at 30-800 mm/s speeds.
Part Ejection
Delivers a fast, compact ejection stroke for small molded components out of a press, fitting tight machinery envelopes.
Replacing the Airtac SU32~50 Standard Cylinder SU50X10 with the SAU50X10
To replace the SU50X10, order the SAU50X10 direct equivalent, verifying your 1/4" port thread (PT, G, or NPT) and SC-series mounting accessories like LB or FA. Because this non-magnetic SKU lacks a sensor groove piston, it cannot take a switch; if sensing is needed, order an SAU50X10-S and migrate to CMSG/DMSG/EMSG switches. For higher loads, the 63 mm bore yields 1559 N push at 0.5 MPa, while smaller 40 mm bores offer 628 N. Remember, a standard cylinder drifts without live air—the 21 mm cushions only decelerate near stroke end—so install an external rod lock or pilot-operated check valve for load holding. The SAUF valve-integrated variant can simplify cycle plumbing if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X10
- ✓ 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 SU50X10 FAQ
Yes, the SU50X10 is discontinued. The direct replacement is the AirTAC SAU50X10. It matches the 50 mm bore, 10 mm stroke, 982 N force, 1/4" port, and SC-series mounting. The SAU body uses current CMSG/DMSG/EMSG sensors and offers an optional SAUF built-in valve.
The 50 mm bore features a 1/4" air port and a 20 mm piston rod. It delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa. This specific non-S SKU cannot accept a magnetic sensor.
