This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X450SN, 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 SU50X450SN
The AirTAC SU32~50 Standard Cylinder SU50X450SN is a double-acting profile-type standard cylinder with a Ø50mm bore and 450mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X450SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X450SN
The AirTAC SU50X450SN is a discontinued double-acting profile cylinder featuring a 50mm bore, 450mm stroke, NBR seals, and a piston magnet. It delivers 982N push and 825N pull at 0.5MPa. The direct replacement is the SAU50X450SN, matching the 1/4" port, M16x1.5 rod thread, and SC-series mounting.
Because the 450mm stroke is long, use external guides to prevent rod bending. Note the SAU upgrade uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B, and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X450SN 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 SAU50X450SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacing the Airtac SU32~50 Standard Cylinder SU50X450SN with the SAU50X450SN
To replace this discontinued SU50X450SN, order the SAU50X450SN direct equivalent, confirming the 1/4" port, M16x1.5 thread, and NBR seals. If sizing down, a 40mm bore gives 628N push at 0.5MPa; if sizing up, a 63mm bore yields 1559N. For the 450mm stroke, add external guides to handle side loads and prevent rod bending. The -S magnet means your old CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU. This cylinder will not hold a load without air; use a pilot-operated check valve or rod lock. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X450SN
- ✓ 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 SU50X450SN FAQ
Yes, the SU50X450SN is discontinued. The direct replacement is the SAU50X450SN, offering the same 50mm bore, 450mm stroke, 982N force, 1/4" port, and SC-series mounting compatibility.
It provides 982N push and 825N pull at 0.5MPa, 1374N at 0.7MPa, and a 200kgf max at 1.0MPa. The -S magnet worked with CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
