This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X150CA, 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 SU50X150CA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X150CA is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X150CA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X150CA
The AirTAC SU50X150CA is a discontinued double-acting profile-type cylinder with a 50mm bore and 150mm stroke. Delivering 982N push force at 0.5MPa through a 1/4" port, its direct replacement is the SAU50X150CA, matching the bore, stroke, force, and SC-series CA mounting. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same size.
This no-magnet SKU cannot take a sensor. The SAU upgrade switches to CMSG/DMSG/EMSG switches and adds a SAUF built-in-valve option the SU lacked. Cushions only decelerate; use a rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X150CA 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 SAU50X150CA 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 SU50X150CA Is Used
Clamping Fixtures
Securing workpieces during machining using the CA clevis mount, allowing pivoting alignment while holding against tooling vibration.
Gate Operation
Opening and closing access gates or safety doors, utilizing the compact profile body to fit within tight machine guarding envelopes.
Replacing the Airtac SU32~50 Standard Cylinder SU50X150CA with the SAU50X150CA
To replace the SU50X150CA, order the SAU50X150CA: it matches the 50mm bore, 150mm stroke, 1/4" port, M16x1.5 rod thread, and CA mounting. Since this SKU lacks the -S magnet, it cannot accept a sensor; if you need position detection on the SAU, you must order the -S version and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. At 150mm stroke, side-load and rod-bending risks are low, but always guide the load. For higher force needs, the 63mm bore yields 1559N push at 0.5MPa; for lighter loads, the 40mm bore gives 628N. Remember, the air cushion only decelerates the piston near stroke end—it will not hold a load on air loss, so add an external rod lock or pilot-operated check valve for vertical holding. The SAUF variant offers a built-in 4M solenoid valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU50X150CA
- ✓ 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 SU50X150CA FAQ
Yes, the AirTAC SU50X150CA is discontinued. The direct replacement is the SAU50X150CA. It shares the identical 50mm bore, 150mm stroke, 982N output force, 1/4" port, and SC-series CA mounting, so it bolts right in.
This double-acting cylinder delivers 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a sensor. The SAU replacement with -S uses CMSG/DMSG/EMSG switches.
