This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X160H, 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 SU50X160H
The AirTAC SU32~50 Standard Cylinder SU50X160H is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X160H, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X160H
The AirTAC SU50X160H is a discontinued double-acting profile-type cylinder with a 50mm bore and 160mm stroke. Built with an extruded aluminium barrel, it is more compact than an ISO 15552 unit of the same size while sharing AirTAC SC-series mounting accessories. This high-temperature variant uses Viton H seals for 0 to 150 C environments.
Because the SU series is end-of-life, the direct replacement is the SAU50X160H. It matches the original 50mm bore, 160mm stroke, 1/4" port, M16x1.5 rod thread, and 21mm cushions perfectly. The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a new SAUF built-in-valve option the SU line never had. Note this SKU lacks a magnet, so it cannot accept position switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X160H 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 SAU50X160H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×160 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU50X160H Is Used
Hot End Ejection
Ideal for pushing parts at 982 N in 0 to 150 C zones using the Viton H seal, handling ejection tasks near ovens or heat tunnels safely.
Transfer Diverting
Provides 825 N pull force at 0.5 MPa to actuate routing gates on packaging lines, with a 160mm stroke clearing standard product profiles.
Replacing the Airtac SU32~50 Standard Cylinder SU50X160H with the SAU50X160H
To replace this SU50X160H, order the SAU50X160H direct equivalent. Confirm the 1/4" port (PT/G/NPT) and your SC-series mounting (LB/FA/FB/CA/CB) carry over directly. Since this is a no-magnet SKU, it cannot take a sensor; if you need position detection on the SAU, add the -S suffix and migrate to CMSG/DMSG/EMSG switches. Sizing both ways: a 40mm bore gives 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N. This 160mm stroke is under the 300mm side-load threshold, but always guide the rod to prevent bending. For loads that must stay put on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. If you want to simplify plumbing, explore the SAUF variant with its integrated 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X160H
- ✓ 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 SU50X160H FAQ
Yes, the SU50X160H is discontinued. The direct replacement is the AirTAC SAU50X160H. It offers identical 50mm bore, 160mm stroke, 1/4" port, output force, and SC-series mounting compatibility, while adding modern sensor and valve options.
At 0.5 MPa it pushes 982 N and pulls 825 N; at 0.7 MPa it pushes 1374 N, with a theoretical max of 200 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept position switches. The SAU replacement supports CMSG/DMSG/EMSG sensors if you specify the -S option.
