This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X550SH, 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 SU50X550SH
The AirTAC SU32~50 Standard Cylinder SU50X550SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 550mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X550SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X550SH
The AirTAC SU50X550SH is a discontinued double-acting profile-type cylinder with a 50mm bore and 550mm stroke. It delivers 982N push force at 0.5MPa through a 1/4" port. AirTAC replaced it with the direct replacement SAU50X550SH, matching the bore, stroke, force, port, and SC-series mounting.
This unit includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU50X550SH replacement upgrades to CMSG/DMSG/EMSG sensors. The H seal provides 0-150C Viton heat resistance.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X550SH 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 SAU50X550SH 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 SU50X550SH Is Used
Extended Transfer Push
Pushes products across 550mm gaps between conveyor belts, requiring external guide rails to prevent rod bending during the long stroke.
Replacing the Airtac SU32~50 Standard Cylinder SU50X550SH with the SAU50X550SH
To replace this SU50X550SH, order the SAU50X550SH direct equivalent, verifying the 50mm bore, 550mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. The -H Viton seal handles 0-150C heat. Sizing both ways: a 40mm bore gives 628N [email protected], while a 63mm bore yields 1559N. For the 550mm stroke, use external guides to prevent rod bending and side-load wear. This plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve for load holding. The SAUF built-in-valve variant is available on the SAU line if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X550SH
- ✓ 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 SU50X550SH FAQ
Yes, the SU50X550SH is discontinued. The direct replacement is the SAU50X550SH, which shares the same 50mm bore, 550mm stroke, 982N force, 1/4" port, and SC-series mounting accessories.
The 50mm bore provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a 200kgf max at 1.0MPa. The -S magnet on this legacy SU works with CS1-B/DS1-B switches, but the SAU50X550SH replacement requires CMSG/DMSG/EMSG sensors.
