This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X110, 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 SU50X110
The AirTAC SU32~50 Standard Cylinder SU50X110 is a double-acting profile-type standard cylinder with a Ø50mm bore and 110mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X110, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X110
The AirTAC SU50X110 is a discontinued double-acting profile-type cylinder with a 50mm bore and 110mm stroke. Delivering 982N push force at 0.5MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same size. AirTAC replaced it with the direct replacement SAU50X110, matching the exact bore, stroke, 1/4" port, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches, and adds a SAUF built-in valve option the SU lacked. Since this SKU has no magnet, it cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X110 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 SAU50X110 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 SU50X110 Is Used
Clamping Fixtures
Ideal for holding medium workpieces during machining, utilizing the 982N push force at 0.5MPa for rigid, stable clamping on automated lines.
Package Diverting
Provides reliable actuation for sorting light-to-medium packages on material handling conveyors, benefiting from the compact 50mm profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU50X110 with the SAU50X110
To replace this discontinued SU50X110, order the SAU50X110. Verify your 1/4" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) which carry over directly. This non-magnetic SKU cannot take a switch; if sensing is needed, specify an SAU50X110-S and use current CMSG/DMSG/EMSG switches. For loads needing 1767N at 0.9MPa, step up to a 63mm bore; if under 628N, a 40mm bore suffices. Remember, the air cushion only decelerates; use an external rod lock or pilot-operated check valve to hold loads securely.
Replacement checklist
- ✓ Same bore / stroke → SAU50X110
- ✓ 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 SU50X110 FAQ
Yes, the AirTAC SU50X110 is discontinued. The direct replacement is the SAU50X110. It shares the identical 50mm bore, 110mm stroke, 982N force at 0.5MPa, 1/4" port, and SC-series mounting, so it fits your existing application directly.
The 50mm bore provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. The air cushions only decelerate the piston; the cylinder will not hold a load without air. Use an external rod lock or pilot-operated check valve for load holding.
