This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X600SLB, 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 SU80X600SLB
The AirTAC SU63-100 Standard Cylinder SU80X600SLB is a double-acting profile-type standard cylinder with a Ø80mm bore and 600mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X600SLB, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X600SLB
The AirTAC SU80X600SLB is a discontinued double-acting profile-type cylinder with an 80mm bore and 600mm stroke. AirTAC replaced this legacy unit with the SAU80X600SLB, a direct replacement retaining the exact 3/8 inch port, M20x1.5 rod thread, 25mm piston rod, and SC-series LB mounting interface.
Upgrading to the SAU80X600SLB keeps the identical profile body, bore, stroke, and output force, but moves the -S magnet sensing to the modern CMSG/DMSG/EMSG switch family (the old SU used CS1-B/DS1-B). The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, a self-switching option the SU never offered. This extruded aluminium profile is shorter and more compact than an ISO 15552 cylinder of the same bore, operating at 30-800mm/s with 28mm adjustable cushions at both ends.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X600SLB 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 SAU80X600SLB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×600 | Stroke length in mm. |
| -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 SU80X600SLB Is Used
Heavy Carton Diversion
Pushes heavy palletized cartons off a main packaging line using the 2513N thrust at 0.5MPa, with the 600mm stroke reaching across a wide conveyor belt.
Large Press Ejection
Ejects formed metal parts from a 80-ton press bed, utilizing the LB mount to fix the body rigidly against the heavy machine frame.
Replacing the Airtac SU63-100 Standard Cylinder SU80X600SLB with the SAU80X600SLB
To replace the discontinued SU80X600SLB, order the SAU80X600SLB direct equivalent, verifying your 3/8 inch port threads (PT/G/NPT) and the SC-series LB mounting accessory. Because this unit has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to the current CMSG/DMSG/EMSG sensors on the SAU. Sizing both ways: if you need less force, the 63mm bore yields 1559N push at 0.5MPa; if you need more, the 100mm bore yields 3927N. A plain cylinder does not hold load on air loss—the cushion only decelerates near stroke end—so fit an external rod lock or pilot-operated check valve for suspended loads. At 600mm stroke, prevent rod bending by guiding the load externally to avoid side-load forces. If valve integration is desired, explore the SAUF built-in-valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU80X600SLB
- ✓ 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 SU80X600SLB FAQ
Yes, the SU80X600SLB is discontinued. The direct replacement is the SAU80X600SLB. It shares the identical 80mm bore, 600mm stroke, 3/8 inch port, 513kgf max force, and SC-series LB mounting, fitting the same application. You simply order the SAU80X600SLB.
The SAU80X600SLB provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf maximum at 1.0MPa. Because your old SU-S magnet worked with CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors on the SAU replacement.
