This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X575, 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 SU50X575
The AirTAC SU32~50 Standard Cylinder SU50X575 is a double-acting profile-type standard cylinder with a Ø50mm bore and 575mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X575, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X575
The AirTAC SU50X575 is a discontinued double-acting profile-type cylinder with a 50mm bore and 575mm stroke. It delivers 982 N push force at 0.5 MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X575, a direct alternative retaining the exact body, stroke, force, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, superseding the legacy CS1-B/DS1-B switches, and offers a new SAUF valve-integrated variant. Note this non-magnetic SKU cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X575 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 SAU50X575 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 SU50X575 Is Used
Material Diversion
Actuates diverter gates on packaging lines, using the 982 N push force to reliably pivot heavy cardboard cartons at speed.
Vertical Lifting
Raises lightweight tote bins up to 50 kg in pick-and-place cells, requiring an external guide to manage the 575mm stroke side-load.
Clamp Actuation
Drives mid-force clamping fixtures on machining stations, taking advantage of the adjustable 21mm cushions to soften end-of-stroke impact.
Replacing the Airtac SU32~50 Standard Cylinder SU50X575 with the SAU50X575
To replace the SU50X575, order the SAU50X575. Verify your 1/4" port thread (PT, G, or NPT), M16x1.5 rod-end, and SC-series mounting (LB/FA/FB/CA/CB). If moving up, the 63mm bore yields 1559 N push at 0.5 MPa; sizing down, the 40mm bore yields 628 N. At 575mm stroke, use an external guide to prevent rod bending and side-load wear. The air cushion only decelerates the piston; it does not hold load on air loss, so add a pilot-operated check valve or external rod lock for vertical loads. This non-magnet version cannot support switches.
Replacement checklist
- ✓ Same bore / stroke → SAU50X575
- ✓ 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 SU50X575 FAQ
Yes, the SU50X575 is discontinued. The direct replacement is the AirTAC SAU50X575. It matches the 50mm bore, 575mm stroke, 1/4" port, output force, and SC-series mounting accessories, fitting the same application directly.
It delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept sensors; the SAU50X575 replacement uses CMSG/DMSG/EMSG switches.
