This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X210CA, 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 SU50X210CA
The AirTAC SU32~50 Standard Cylinder SU50X210CA is a double-acting profile-type standard cylinder with a Ø50mm bore and 210mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X210CA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X210CA
The AirTAC SU50X210CA is a discontinued double-acting profile-type cylinder with a 50mm bore, 210mm stroke, and a 1/4" port. Delivering 982 N of push force at 0.5 MPa, it features an extruded aluminum barrel that is shorter and more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this end-of-life unit with the SAU50X210CA, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series CA mounting interface.
Because this specific SKU lacks a magnet (-S), it cannot accept a sensor. If sensing is needed on the SAU upgrade, note that the legacy CS1-B/DS1-B switches are replaced by the current CMSG/DMSG/EMSG family. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X210CA 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 SAU50X210CA 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 SU50X210CA Is Used
Package Diverting
Actuates diverting arms on packaging lines, using the 982 N push force at 0.5 MPa to redirect cartons reliably without requiring the full 1.0 MPa maximum pressure.
Clamping Fixtures
Secures workpieces during machining operations via the CA mount, where the 21mm adjustable air cushions absorb shock at the 210mm stroke endpoints.
Replacing the Airtac SU32~50 Standard Cylinder SU50X210CA with the SAU50X210CA
To replace the SU50X210CA, order the SAU50X210CA. Verify your 1/4" port thread (PT, G, or NPT) and confirm the CA mounting accessory from the AirTAC SC series. Since this original SKU has no magnet, it cannot hold a piston switch; the SAU upgrade uses CMSG/DMSG/EMSG sensors if you add the -S option. For loads requiring 1374 N at 0.7 MPa, this 50mm bore is ideal, whereas stepping down to a 40mm bore drops push force to 628 N. At a 210mm stroke, ensure adequate guide support to prevent rod bending and side-load damage. Remember that a standard cylinder does not hold load without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for fail-safe holding. The SAUF valve-integrated variant is also available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU50X210CA
- ✓ 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 SU50X210CA FAQ
Yes, the SU50X210CA is discontinued. The direct replacement is the SAU50X210CA. It matches the original 50mm bore, 210mm stroke, 1/4" port, output force, and SC-series CA mounting, while offering a more modern sensor groove design.
This 50mm bore cylinder provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept sensors; the SAU replacement uses CMSG/DMSG/EMSG switches if ordered with the -S magnet option.
