This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X50SCB, 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 SU50X50SCB
The AirTAC SU32~50 Standard Cylinder SU50X50SCB 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 SAU50X50SCB, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X50SCB
The AirTAC SU50X50SCB is a discontinued double-acting profile-type cylinder with a 50mm bore and 50mm stroke, delivering 982N push force at 0.5MPa. AirTAC replaced it with the SAU50X50SCB direct replacement, matching the exact bore, stroke, 1/4" port, and SC-series CB mounting. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same size.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this model's legacy CS1-B/DS1-B switches, and offers a new SAUF built-in-valve variant. Note that air cushions only decelerate; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X50SCB 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 SAU50X50SCB 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 SU50X50SCB Is Used
Short-Stroke Clamping
Ideal for holding parts during machining, delivering 982N of push force at 0.5MPa within a compact 50mm stroke.
Package Diverting
Provides reliable actuation for pushing light to medium cartons off a conveyor belt using the CB clevis mount.
Replacing the Airtac SU32~50 Standard Cylinder SU50X50SCB with the SAU50X50SCB
To replace the SU50X50SCB, order the SAU50X50SCB. Confirm the 50mm bore, 50mm stroke, 1/4" port (PT/G/NPT), M16x1.5 rod thread, and CB mounting. Because this SKU has a magnet (-S), you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. If sizing alternatives, the neighboring 40mm bore yields 628N push at 0.5MPa, while the 63mm bore yields 1559N. For any load that must be held without live air, the cushion will not lock the piston; install a pilot-operated check valve or external rod lock. The SAUF variant adds a built-in 4M solenoid valve if you need self-switching. At 50mm stroke, side-load bending is minimal, but always guide the load rigidly.
Replacement checklist
- ✓ Same bore / stroke → SAU50X50SCB
- ✓ 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 SU50X50SCB FAQ
Yes, the SU50X50SCB is discontinued. The direct replacement is the SAU50X50SCB. It shares the identical 50mm bore, 50mm stroke, 982N force, 1/4" port, and SC-series CB mounting. You simply order the SAU equivalent.
The 50mm bore provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. Because this model includes a magnet (-S), note that the SAU replacement switches from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
