This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X600S, 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 SU63X600S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X600S is a double-acting profile-type standard cylinder with a Ø63mm bore and 600mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X600S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X600S
The AirTAC SU63X600S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 600 mm stroke. Delivering 1559 N push force at 0.5 MPa, its direct replacement is the SAU63X600S, retaining the same body dimensions, 3/8" port, and SC-series mounting. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches, whereas the SAU replacement upgrades to current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never had. Note that a 600 mm stroke requires external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X600S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU63X600S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU63X600S Is Used
Vertical Lift Gate
Raises a 79 kg material gate using the 1559 N thrust at 0.5 MPa, requiring a pilot-operated check valve to prevent drifting on air loss.
Multi-Station Indexing
Transfers 60 kg assembly fixtures between stations over 600 mm, relying on adjustable end cushions to decelerate the moving mass smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X600S with the SAU63X600S
To replace this discontinued SU63X600S, order the SAU63X600S, confirming the 63 mm bore, 600 mm stroke, M16x1.5 rod thread, and 3/8" port. Retain your SC-series mounting accessories, as they fit the SAU unchanged. If downsizing, a 50 mm bore yields 982 N push at 0.5 MPa; if upsizing, an 80 mm bore provides 2513 N. The -S magnet means you must switch from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For the 600 mm stroke, add external guides to prevent rod bending. This cylinder will not hold a load without live air; use an external rod lock or pilot-operated check valve for holding, as cushions only decelerate. Consider the SAUF variant if you need a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X600S
- ✓ 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 SU63X600S FAQ
Yes, the SU63X600S is discontinued. The direct replacement is the AirTAC SAU63X600S. It matches the 63 mm bore, 600 mm stroke, 1559 N force, 3/8" port, and SC-series mounting. You simply order the SAU equivalent.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf theoretical max at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are retired; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
