This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X15, 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 SU50X15
The AirTAC Airtac SU32~50 Standard Cylinder SU50X15 is a double-acting profile-type standard cylinder with a Ø50mm bore and 15mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X15, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X15
The AirTAC SU50X15 is a discontinued double-acting profile-type cylinder with a 50mm bore and 15mm stroke. It delivers 982N push force at 0.5MPa through a 1/4" port. AirTAC replaced this with the SAU50X15, a direct upgrade retaining the exact body, stroke, force, and SC-series mounting.
This compact extruded-aluminium barrel is shorter than same-bore ISO cylinders. The SAU upgrade switches to CMSG/DMSG/EMSG sensors and adds a SAUF valve-integrated option. Note: this no-magnet SKU cannot accept a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X15 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 SAU50X15 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 SU50X15 Is Used
Short-Stroke Clamping
Ideal for holding parts during machining, delivering 982N of push force at 0.5MPa within a tight 15mm travel envelope.
Package Diverting
Provides rapid 15mm actuation to push small to medium cartons off a production line at speeds between 30 and 800mm/s.
Ejector Mechanism
Compact profile body fits neatly into tight machine frames to eject finished components from a fixture with precise motion.
Replacing the Airtac SU32~50 Standard Cylinder SU50X15 with the SAU50X15
To replace this discontinued SU50X15, order the SAU50X15 keeping the 50mm bore, 15mm stroke, M16x1.5 rod thread, and 1/4" port. Because this SKU lacks a magnet (-S), it cannot accept a sensor; if you need position detection, select an SAU50X15S and use CMSG/DMSG/EMSG switches (the SU used CS1-B/DS1-B). For sizing, a 40mm bore gives 628N [email protected], while a 63mm bore gives 1559N. The cushion only decelerates; use an external rod lock or pilot-operated check valve to hold loads. For high-cycle automation, consider the SAUF variant with its built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X15
- ✓ 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 SU50X15 FAQ
Yes, the AirTAC SU50X15 is discontinued. The direct replacement is the SAU50X15. It matches the 50mm bore, 15mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it fits the same application without modification.
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 adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. For load holding on air loss, use an external rod lock or pilot-operated check valve.
