This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X50TC, 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 SU50X50TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 50mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X50TC, which matches its bore, stroke, force and mounting.
The AirTAC SU50X50TC is a discontinued double-acting profile-type cylinder with a 50mm bore and 50mm stroke. It delivers 982N push force at 0.5MPa through a 1/4" port. AirTAC replaced this unit with the SAU50X50TC, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors and a SAUF built-in-valve option the SU lacked. Note this non-magnetic SKU cannot accept a sensor switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X50TC 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 SAU50X50TC 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. |
| ×50 | 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.
Uses the TC mount to push parcels on a 50mm stroke, operating safely within the 589N working load limit for reliable sorting.
Provides 982N of push force at 0.5MPa to secure light workpieces during machining, fitting neatly into compact cells.
Functions as a pneumatic stop in material handling lines, using its 50kg vertical lift capacity to control item flow.
To replace the SU50X50TC, order the SAU50X50TC. Verify your 1/4" port thread (PT, G, or NPT) and the M16x1.5 rod-end. The SC-series TC mounting accessory transfers over directly. If stepping up force, the 63mm bore yields 1559N push at 0.5MPa; stepping down, the 40mm bore gives 628N. Since this SKU lacks a magnet, it cannot support sensing. If holding a load mid-stroke is required, add an external rod lock or pilot-operated check valve, as the 21mm adjustable cushions only decelerate near stroke ends.
Replacement checklist
Yes, the SU50X50TC is discontinued. The direct replacement is the AirTAC SAU50X50TC. It shares the same 50mm bore, 50mm stroke, 982N force, 1/4" port, and TC mounting, so it fits the same application without modification.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor switch. The SAU replacement uses CMSG/DMSG/EMSG sensors on magnetized versions.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU50X50TC replacement — usually within 7-8 hours.
