This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X35, 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 SU50X35
The AirTAC Airtac SU32~50 Standard Cylinder SU50X35 is a double-acting profile-type standard cylinder with a Ø50mm bore and 35mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X35, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X35
The AirTAC SU50X35 is a discontinued double-acting profile-type cylinder with a 50mm bore and 35mm stroke. It delivers 982N push and 825N pull at 0.5MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X35, a direct upgrade sharing the exact same extruded body dimensions, M16x1.5 rod thread, output force and SC-series mounting accessories.
Because this 35mm stroke SKU lacks a magnet, it cannot accept position sensors. If sensing is required, the SAU replacement adds a modern magnetic groove for CMSG/DMSG/EMSG switches (the SU line used older CS1-B/DS1-B units). The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, a feature the original SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X35 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 SAU50X35 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 SU50X35 Is Used
Short-Stroke Clamping
Ideal for holding parts during machining, delivering 982N of clamping force at 0.5MPa within a tight 35mm travel envelope.
Package Diverting
Provides a fast 30-800mm/s actuation to push cartons off a conveyor belt, with a compact profile body that fits under tight guards.
Pallet Stop Gate
Acts as a reliable stop mechanism in pallet flow systems, using its 825N pull force to retract the gate and let pallets pass.
Replacing the Airtac SU32~50 Standard Cylinder SU50X35 with the SAU50X35
To replace the SU50X35, order the SAU50X35 by confirming the 50mm bore, 35mm stroke, 1/4" port, and PT/G/NPT thread choice. Reuse your existing SC-series mounting brackets. Since this specific SKU has no magnet (-S), it cannot support sensing; if you need position feedback, specify an SAU50X35S and upgrade to CMSG/DMSG/EMSG switches. For force context, stepping down to a 40mm bore yields 628N push, while stepping up to a 63mm bore provides 1559N. A plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve for held loads. The 35mm stroke is short enough that rod bending is negligible, but always guide the load to prevent side-loading.
Replacement checklist
- ✓ Same bore / stroke → SAU50X35
- ✓ 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 SU50X35 FAQ
Yes, the AirTAC SU50X35 is discontinued. The direct replacement is the SAU50X35, which matches the 50mm bore, 35mm stroke, 1/4" port, force output, and SC-series mounting accessories.
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 air cushion only decelerates the piston near stroke end; it does not hold the load on air loss, so use an external rod lock for vertical safety.
