This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X20TC, 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 SU50X20TC
The AirTAC SU32~50 Standard Cylinder SU50X20TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 20mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X20TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X20TC
The AirTAC SU50X20TC is a discontinued double-acting profile-type cylinder with a 50mm bore and 20mm stroke. AirTAC replaced this unit with the SAU50X20TC direct replacement, matching the exact bore, stroke, output force, port size, and SC-series TC mounting.
The SAU upgrade retains the compact extruded aluminum barrel, shorter than an ISO 15552 equivalent, while introducing current CMSG/DMSG/EMSG sensors. This specific SU50X20TC lacks a magnet, so it cannot accept any sensor. The SAU family also adds a SAUF variant with a built-in 4M solenoid valve, an option the original SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X20TC 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 SAU50X20TC 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 SU50X20TC Is Used
Short-Stroke Clamping
Ideal for applying 982N of clamping pressure on machining fixtures where a 20mm stroke secures parts quickly without excessive travel.
Package Diverting
Provides rapid actuation for diverting lightweight packages on a conveyor line, utilizing the TC mount for stable trunnion mounting.
Replacing the Airtac SU32~50 Standard Cylinder SU50X20TC with the SAU50X20TC
To replace the SU50X20TC, order the SAU50X20TC. Verify your 1/4" port thread (PT, G, or NPT), the M16x1.5 rod end, and the SC-series TC mounting accessory. Because this 20mm stroke SKU has no magnet (-S), it cannot support position sensing; if you need switches, select an SAU50X20TC-S and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For sizing, the 50mm bore provides 982N push at 0.5MPa; if less force is needed, a 40mm bore offers 628N, while a 63mm bore provides 1559N. Note that a plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for load holding. The SAUF valve-integrated model is also worth considering for compact self-switching setups.
Replacement checklist
- ✓ Same bore / stroke → SAU50X20TC
- ✓ 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 SU50X20TC FAQ
Yes, the AirTAC SU50X20TC is discontinued. The direct replacement is the SAU50X20TC, which shares the same 50mm bore, 20mm stroke, 982N force, 1/4" port, and SC-series TC mounting. You can install the SAU model directly into your existing setup.
At 0.5MPa it provides 982N push and 825N pull force, increasing to 1374N push at 0.7MPa, with a theoretical max of 200kgf at 1.0MPa. This specific SU50X20TC lacks a magnet, meaning it cannot accept position sensors; if sensing is required, the SAU-S replacement uses CMSG/DMSG/EMSG switches.
