This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X100SCA, 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 SU50X100SCA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X100SCA is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X100SCA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X100SCA
The AirTAC SU50X100SCA is a discontinued double-acting profile-type cylinder with a 50mm bore and 100mm stroke. It delivers 982N push force at 0.5MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X100SCA, a direct upgrade retaining the exact bore, stroke, output force, and SC-series CA mounting interface.
Because the extruded aluminium body has no external rods, it is shorter than a standard ISO cylinder of the same size. The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the SU's legacy CS1-B/DS1-B switches, and adds a SAUF built-in-valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X100SCA 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 SAU50X100SCA 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 SU50X100SCA Is Used
Clamping Fixtures
Applies the 982N push force at 0.5MPa to secure medium workpieces during machining operations.
Package Diverting
Uses the 100mm stroke to push cartons off a main conveyor belt line at up to 800mm/s.
Material Stops
Acts as a pneumatic stop gate for pallets, handling the 50kg vertical lift capacity safely.
Replacing the Airtac SU32~50 Standard Cylinder SU50X100SCA with the SAU50X100SCA
To replace the SU50X100SCA, order the SAU50X100SCA. Verify your 1/4" port threads (PT, G, or NPT) and the M16x1.5 rod end. The CA mounting accessory is reused directly. If downsizing, a 40mm bore yields 628N push at 0.5MPa; if upsizing, a 63mm bore provides 1559N. The -S magnet on this SKU means you must migrate from CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate the load; for fail-safe holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X100SCA
- ✓ 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 SU50X100SCA FAQ
Yes, the SU50X100SCA is discontinued. The direct replacement is the SAU50X100SCA, which shares the same 50mm bore, 100mm stroke, 1/4" port, and CA mounting. You must upgrade your sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG family.
This double-acting cylinder has a 1/4" air port. It generates 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical maximum of 200kgf at 1.0MPa. The 21mm adjustable cushions only decelerate the load; they do not hold position without live air.
