This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X35N, 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 SU50X35N
The AirTAC SU32~50 Standard Cylinder SU50X35N 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 SAU50X35N, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X35N
The AirTAC SU50X35N is a discontinued double-acting profile-type cylinder with a 50mm bore and 35mm stroke. Delivering 982N push force at 0.5MPa, it features an extruded aluminum barrel and adjustable air cushions at both ends. The direct replacement is the SAU50X35N, matching the exact bore, stroke, output force, 1/4" port, and SC-series mounting.
This NBR-sealed unit operates from -20 to +70C. Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade switches to CMSG/DMSG/EMSG switches for -S variants and adds a SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X35N 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 SAU50X35N 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 SU50X35N Is Used
Clamping Mechanisms
Provides 982N of clamping thrust at 0.5MPa for securing mid-weight machined components during milling or drilling operations.
Package Diverting
Executes short 35mm strokes to push small to medium parcels off a main conveyor line into sorting chutes efficiently.
Stopper Gates
Acts as a pneumatic stop in material handling systems, halting pallets or product totes momentarily at inspection stations.
Replacing the Airtac SU32~50 Standard Cylinder SU50X35N with the SAU50X35N
To replace this SU50X35N, order the SAU50X35N direct equivalent, verifying the 50mm bore, 35mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. This non-magnetic SKU cannot accept switches; if sensing is needed, specify an -S SAU model and migrate to CMSG/DMSG/EMSG sensors. For higher loads, a 63mm bore yields 1559N push at 0.5MPa. Note that air cushions only decelerate the piston; use an external rod lock or pilot-operated check valve to hold loads securely. The SAUF variant integrates a 4M valve if space is tight.
Replacement checklist
- ✓ Same bore / stroke → SAU50X35N
- ✓ 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 SU50X35N FAQ
Yes, the AirTAC SU50X35N is discontinued. The direct replacement is the SAU50X35N, offering identical 50mm bore, 35mm stroke, 982N force, 1/4" port, and SC-series mounting compatibility.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa push is 1374N, with a theoretical max of 200kgf at 1.0MPa. This specific SKU has no magnet and cannot accept sensors; the SAU -S variant uses CMSG/DMSG/EMSG switches.
