This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1350, 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 SU50X1350
The AirTAC SU32~50 Standard Cylinder SU50X1350 is a double-acting profile-type standard cylinder with a Ø50mm bore and 1350mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1350, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1350
The AirTAC SU50X1350 is a discontinued double-acting profile-type cylinder with a 50mm bore and 1350mm stroke. Because 1350mm exceeds the 1200mm standard maximum for this bore, it is a non-standard, made-to-order item. It delivers 982 N push force at 0.5 MPa and features a 1/4" port.
The direct replacement is the SAU50X1350, matching the body, stroke, force, port and SC-series mounting. This SKU lacks a magnet (-S) and cannot take a sensor. The SAU upgrade uses current CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X1350 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 SAU50X1350 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 SU50X1350 Is Used
Long-Reach Diversion
Pushes heavy packages across a wide conveyor belt sorting line using the 1350mm stroke and 982 N push force at 0.5 MPa.
Material Transfer
Transfers automotive components between distant workstations, utilizing the 1/4" port and compact profile body to save space.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1350 with the SAU50X1350
To replace this SU50X1350, order the SAU50X1350 direct equivalent, confirming the 50mm bore, 1350mm non-standard stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. Since this is a no-S SKU, it cannot accept a magnetic sensor. For sizing, a 40mm bore gives 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N. At 1350mm, the stroke exceeds the 1200mm standard maximum, requiring a made-to-order configuration. Prevent rod bending on this long stroke by using an external guide to absorb side loads. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1350
- ✓ 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 SU50X1350 FAQ
Yes, the AirTAC SU50X1350 is discontinued. The direct replacement is the SAU50X1350, which shares the same 50mm bore, 1350mm stroke, 982 N force, 1/4" port, and SC-series mounting accessories.
It delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf max at 1.0 MPa. This specific SKU has no magnet and cannot accept a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches on its -S variants.
