This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1300, 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 SU50X1300
The AirTAC SU32~50 Standard Cylinder SU50X1300 is a double-acting profile-type standard cylinder with a Ø50mm bore and 1300mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1300, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1300
The AirTAC SU50X1300 is a discontinued double-acting profile-type cylinder with a 50mm bore and 1300mm stroke. Because 1300mm exceeds the 1200mm standard maximum for this bore, it is a non-standard, made-to-order length.
AirTAC replaced the SU line with the SAU50X1300, a direct replacement retaining the exact bore, stroke, force, 1/4" port, and SC-series mounting. The SAU upgrade adopts modern CMSG/DMSG/EMSG sensors and introduces the SAUF built-in 4M solenoid valve variant. Note this specific SKU lacks a magnet (-S), so it cannot accept any magnetic switch. For the 1300mm length, external guides are strongly recommended to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X1300 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 SAU50X1300 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU32~50 Standard Cylinder SU50X1300 Is Used
Long-Stroke Diversion
Pushes packages across extended conveyor lanes, utilizing the full 1300mm travel with external guides to prevent rod deflection.
High-Bay Pusher
Actuates pallets or totes in automated storage systems where a 50kg vertical lift capacity at 0.5 MPa is sufficient.
Material Transfer Arm
Moves workpieces between machining stations, relying on the 982 N push force and adjustable 21mm end cushions for smooth stops.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1300 with the SAU50X1300
To replace this discontinued SU50X1300, order the SAU50X1300 direct equivalent, verifying your 1/4" port thread (PT/G/NPT), M16x1.5 rod-end, and SC-series mounting (LB/FA/FB/CA/CB). Since this is a non-standard 1300mm stroke exceeding the 1200mm max, expect made-to-order lead times and ensure external guides are fitted to prevent rod-bending on long strokes. If sizing alternatives, a 40mm bore provides 628 N push @0.5 MPa, while a 63mm bore offers 1559 N. A plain cylinder drifts on air loss—the 21mm cushions only decelerate—so add an external rod lock or pilot-operated check valve for load holding. If self-switching is needed, the SAUF integrates a valve the SU lacked; just note this no-magnet SKU cannot mount legacy CS1-B/DS1-B or modern CMSG/DMSG/EMSG switches.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1300
- ✓ 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 SU50X1300 FAQ
Yes, the SU50X1300 is discontinued. The direct replacement is the AirTAC SAU50X1300. It shares the identical 50mm bore, 1300mm stroke, 982 N push force at 0.5 MPa, 1/4" port, and SC-series mounting accessories, so it drops directly into the same application.
This 50mm bore cylinder 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 magnetic switches (legacy CS1-B/DS1-B or the SAU's CMSG/DMSG/EMSG). The SAU replacement also offers the SAUF built-in valve variant.
