This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X770SCA, 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 SU50X770SCA
The AirTAC SU32~50 Standard Cylinder SU50X770SCA is a double-acting profile-type standard cylinder with a Ø50mm bore and 770mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X770SCA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X770SCA
The AirTAC SU50X770SCA is a discontinued double-acting profile-type cylinder with a 50mm bore, 770mm stroke, and a CA mounting interface. It delivers 982 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this end-of-life unit with the SAU50X770SCA, a direct replacement retaining the exact bore, stroke, force, and SC-series mounting footprint.
The SAU upgrade switches the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in valve option the SU line lacked. Note that standard cylinders drift without live air; the cushions only decelerate, so use an external rod lock for holding.

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 SAU50X770SCA 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 SU50X770SCA Is Used
Long-Stroke Diversion
Pushes packages across transfer lines using the 770mm stroke, relying on external guides to prevent rod bending during lateral extension.
CA-Mount Assembly Press
Applies up to 1374 N of push force at 0.7 MPa for seating components, utilizing the clevis mount to accommodate angular alignment.
Replacing the Airtac SU32~50 Standard Cylinder SU50X770SCA with the SAU50X770SCA
To replace this SU50X770SCA with the SAU50X770SCA, verify the 50mm bore, 770mm stroke, 1/4" port, M16x1.5 rod thread, and CA mounting accessory. Because this SKU includes the -S magnet, prepare to upgrade your legacy CS1-B/DS1-B switches to the SAU-compatible CMSG/DMSG/EMSG family. When sizing, the 50mm bore yields 982 N push at 0.5 MPa; stepping down to a 40mm bore drops thrust to 628 N, while an 80mm bore provides 2513 N. The 770mm stroke demands external guides to prevent rod bending and side-load damage. For loads that must stay put during air loss, add a pilot-operated check valve or external rod lock, as the air cushion only decelerates. If self-switching is needed, explore the SAUF variant with its integrated 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X770SCA
- ✓ 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 SU50X770SCA FAQ
Yes, the SU50X770SCA is discontinued. The direct replacement is the AirTAC SAU50X770SCA. It matches the 50mm bore, 770mm stroke, 982 N force at 0.5 MPa, 1/4" port, and CA mounting. You will only need to upgrade your sensors from the old CS1-B/DS1-B to the new CMSG/DMSG/EMSG family.
This double-acting cylinder features a 1/4" port and generates 982 N push and 825 N pull at 0.5 MPa. At 0.7 MPa it pushes 1374 N, and the theoretical maximum force is 200 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
