This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1050S, 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 SU50X1050S
The AirTAC SU32~50 Standard Cylinder SU50X1050S is a double-acting profile-type standard cylinder with a Ø50mm bore and 1050mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1050S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1050S
The AirTAC SU50X1050S is a discontinued double-acting profile-type cylinder with a 50mm bore and 1050mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this EOL unit with the SAU50X1050S, a direct sharing the same body, force, and SC-series mounts.
Because this is a 1050mm nonstandard stroke exceeding the 1200mm max standard, you must use external guides to prevent rod bending. The -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU uses CMSG/DMSG/EMSG sensors. The SAUF valve-integrated option is also new.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X1050S 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 SAU50X1050S 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 SU50X1050S Is Used
Long-Stroke Material Push
Ideal for transferring products across wide conveyor belts where the 982N push force at 0.5MPa easily handles standard carton weights.
High-Bay Diversion
Useful in automated storage for actuating diverter arms at height, provided external guides support the 1050mm stroke to prevent rod bending.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1050S with the SAU50X1050S
To replace this discontinued SU50X1050S, order the SAU50X1050S direct. Verify your 1/4" port, M16x1.5 rod thread, and SC-series mounts. Since the -S magnet is present, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. At 1050mm, external guides are mandatory to prevent rod bending. If sizing down, a 40mm bore gives 628N push; sizing up to 63mm yields 1559N. A plain cylinder drifts on air loss, so use a rod lock for held loads. Consider the SAUF variant for a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1050S
- ✓ 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 SU50X1050S FAQ
Yes, the SU50X1050S is discontinued. The direct replacement is the SAU50X1050S, which shares the exact 50mm bore, 1050mm stroke, 982N force, 1/4" port, and SC-series mounting accessories.
It provides 982N push and 825N pull at 0.5MPa, 1374N at 0.7MPa, and a 200kgf max at 1.0MPa. The -S magnet used legacy CS1-B/DS1-B switches; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
