This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X195SFA, 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.

The AirTAC SU32~50 Standard Cylinder SU50X195SFA is a double-acting profile-type standard cylinder with a Ø50mm bore and 195mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X195SFA, which matches its bore, stroke, force and mounting.
The AirTAC SU50X195SFA is a discontinued double-acting profile-type cylinder with a 50 mm bore and 195 mm stroke. It delivers 982 N push force at 0.5 MPa through a 1/4 inch port. AirTAC replaced this unit with the SAU50X195SFA, a direct upgrade sharing the exact same body dimensions, output, and SC-series FA mounting accessories.
When upgrading, note that your -S magnet equipped SU used legacy CS1-B or DS1-B switches, whereas the SAU replacement requires current CMSG, DMSG, or EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X195SFA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X195SFA 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. |
| ×195 | 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.
Provides 982 N of push force at 0.5 MPa to secure mid-weight workpieces during machining operations.
Uses the 195 mm stroke to push cartons off a main conveyor belt into secondary packaging lanes.
To replace your SU50X195SFA, order the SAU50X195SFA. Confirm the 50 mm bore, 195 mm stroke, M16x1.5 rod thread, and 1/4 inch port (default PT). The FA mounting is an SC-series accessory that transfers directly. Because this SKU includes the -S magnet, you must swap your old CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the new cylinder. If sizing alternatives, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa, while the 63 mm bore offers 1559 N. A plain cylinder does not hold load without live air; the 21 mm cushions only decelerate, so add an external rod lock or pilot-operated check valve for vertical holding. For higher flow control needs, consider the SAUF built-in valve variant.
Replacement checklist
Yes, the SU50X195SFA is discontinued. The direct replacement is the SAU50X195SFA. It matches the 50 mm bore, 195 mm stroke, 1/4 inch port, output force, and SC-series FA mounting interface, so it fits the same application directly.
The 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because this model has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG, DMSG, or EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU50X195SFA replacement — usually within 7-8 hours.
