This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X170STC, 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 SU50X170STC
The AirTAC SU32~50 Standard Cylinder SU50X170STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 170mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X170STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X170STC
The AirTAC SU50X170STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 170mm stroke. Built with an extruded aluminum barrel, it is shorter than an ISO 15552 cylinder of the same bore while delivering 982 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAU50X170STC, a direct upgrade retaining the exact 1/4" port, M16x1.5 rod thread, and SC-series TC mounting interface.
When migrating to the SAU50X170STC, your body dimensions, bore, stroke, and output force remain identical. The upgrade introduces current CMSG/DMSG/EMSG sensors to replace the older CS1-B/DS1-B switches used on this -S SKU, and the SAU line adds an optional SAUF variant with a built-in 4M solenoid valve the SU series never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X170STC 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 SAU50X170STC 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. |
| ×170 | 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 SU50X170STC Is Used
Package Diverting
Drives diverting arms on packaging lines where the 982 N push force easily redirects cartons at 30-800 mm/s operating speeds.
Clamp Actuation
Secures medium workpieces during machining using the TC mount for stable centerline support against lateral shift.
Replacing the Airtac SU32~50 Standard Cylinder SU50X170STC with the SAU50X170STC
To replace the SU50X170STC, order the SAU50X170STC ensuring your 1/4" port threads (PT/G/NPT) and TC mounting match. Because this SKU includes a magnet, note that your legacy CS1-B/DS1-B switches must change to the SAU's CMSG/DMSG/EMSG sensor family. If sizing alternatives, the neighboring 40mm bore yields 628 N push at 0.5 MPa, while the 63mm bore provides 1559 N. Remember that a standard cylinder drifts without live air; the 21mm adjustable cushions only decelerate near stroke end, so fit an external rod lock or pilot-operated check valve for held loads. At 170mm stroke, rod bending is low, but always guide the load to prevent side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU50X170STC
- ✓ 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 SU50X170STC FAQ
Yes, the SU50X170STC is discontinued. The direct replacement is the AirTAC SAU50X170STC. It shares the same 50mm bore, 170mm stroke, 1/4" port, 982 N output force, and TC mounting, so it drops right into the same application.
The 50mm bore delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N at 0.7 MPa, and a 200 kgf theoretical max at 1.0 MPa. Because this is an -S magnet SKU, the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU upgrade.
