This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X500S, 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 SU63X500S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X500S is a double-acting profile-type standard cylinder with a Ø63mm bore and 500mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X500S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X500S
The AirTAC SU63X500S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 500 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU63X500S, a direct upgrade retaining the exact bore, stroke, force, port, and SC-series mounting.
The compact extruded aluminum body is shorter than an ISO 15552 cylinder of the same bore. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors, and the SAU line adds a SAUF built-in valve option.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X500S 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 SU63X500S Is Used
Long-Stroke Diverting
Pushes packages across a 500 mm lane transition on a sorting line, utilizing the 1559 N thrust to overcome friction without lateral binding.
Multi-Stage Ejection
Extends 500 mm to eject machined parts from a deep fixture, relying on adjustable end cushions to decelerate the 20 mm rod smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X500S with the SAU63X500S
To replace this SU63X500S, order the SAU63X500S direct equivalent. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting accessories remain compatible. If sizing alternatives, the adjacent 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N. Because this is a 500 mm stroke, use external guides to prevent rod bending and side-load damage. The -S magnet means you must upgrade from CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate the load; for secure holding on air loss, install an external rod lock or pilot-operated check valve. The SAUF variant offers a built-in 4M solenoid valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU63X500S
- ✓ 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 SU63X500S FAQ
Yes, the SU63X500S is discontinued. The direct replacement is the AirTAC SAU63X500S. It matches the 63 mm bore, 500 mm stroke, 3/8" port, and SC-series mounting. The main upgrade is that the -S magnet now requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
This double-acting cylinder has a 3/8" air port. At 0.5 MPa it provides 1559 N push and 1402 N pull force. At 0.7 MPa push is 2182 N, and at 0.9 MPa it is 2805 N. The theoretical maximum force is 318 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
