This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X50CA, 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 SU63-100 Standard Cylinder SU80X50CA
The AirTAC Airtac SU63-100 Standard Cylinder SU80X50CA is a double-acting profile-type standard cylinder with a Ø80mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X50CA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X50CA
The AirTAC SU80X50CA is a discontinued double-acting profile-type cylinder with an 80mm bore and 50mm stroke, delivering 2513N push force at 0.5MPa. AirTAC replaced it with the SAU80X50CA, a direct upgrade retaining the exact bore, stroke, 3/8" port, and SC-series CA mounting.
This extruded aluminium body is shorter than an ISO 15552 equivalent. Since this SKU lacks a magnet, it cannot accept sensors, whereas the SAU upgrade supports modern CMSG/DMSG/EMSG switches. Note that cushions only decelerate; use a rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X50CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X50CA 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 SU63-100 Standard Cylinder SU80X50CA Is Used
Heavy Stamp Ejection
Provides 2513N of push at 0.5MPa to eject stamped metal parts from a press die, utilizing the CA clevis mount to handle pivoting articulation.
Pallet Diverting
Swings a heavy lane diverter on a packaging conveyor line, where the compact profile body saves space and the 50mm stroke moves the guide quickly.
Bin Lift Actuation
Drives a short 50mm lifting lever to tilt bulk component bins, safely moving loads up to 1508N without exceeding a 0.5MPa working pressure.
Replacing the Airtac SU63-100 Standard Cylinder SU80X50CA with the SAU80X50CA
To replace this discontinued SU80X50CA, order the SAU80X50CA to match the 80mm bore, 50mm stroke, 3/8" port, M20x1.5 rod thread, and CA mounting. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore gives 3927N. Because this non-magnetic SKU cannot take a sensor, position detection requires external limits. The SAU family also adds the SAUF built-in 4M valve option absent from the SU line. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. The 50mm stroke avoids rod-bending side-load risks seen in long strokes.
Replacement checklist
- ✓ Same bore / stroke → SAU80X50CA
- ✓ 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 SU63-100 Standard Cylinder SU80X50CA FAQ
Yes, the AirTAC SU80X50CA is discontinued. The direct replacement is the SAU80X50CA. It shares the identical 80mm bore, 50mm stroke, 2513N force, 3/8" port, and CA mounting, so it fits the same application directly.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf maximum at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept piston sensors; the SAU replacement uses CMSG/DMSG/EMSG switches.
