This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X900TC, 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 SU80X900TC
The AirTAC SU63-100 Standard Cylinder SU80X900TC is a double-acting profile-type standard cylinder with a Ø80mm bore and 900mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X900TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X900TC
The AirTAC SU80X900TC is a discontinued double-acting profile-type cylinder with an 80mm bore and 900mm stroke. It delivers 2513N push force at 0.5MPa via a 3/8" port. AirTAC replaced it with the SAU80X900TC direct replacement, matching the exact bore, stroke, output, port, and SC-series TC mounting.
The SAU upgrade switches to current CMSG/DMSG/EMSG sensors, whereas this legacy SU used CS1-B/DS1-B switches. This no-magnet SKU cannot take a sensor. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X900TC 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 SAU80X900TC 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 SU80X900TC Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across a 900mm gap on a production line using 2513N of thrust at 0.5MPa.
Pallet Positioning Gate
Acts as a high-force stopper or diverter on a TC-mounted logistics conveyor, handling substantial inertial loads.
Large Assembly Press
Provides steady clamping or pressing force for large component fabrication, relying on adjustable 28mm cushions for end-of-stroke deceleration.
Replacing the Airtac SU63-100 Standard Cylinder SU80X900TC with the SAU80X900TC
To replace this SU80X900TC, order the SAU80X900TC direct equivalent, verifying the 80mm bore, 900mm stroke, 3/8" port, M20x1.5 rod thread, and TC mounting. Because this SKU lacks a magnet, it cannot accept a sensor; if sensing is needed, specify an SAU -S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. If you need higher force, the 100mm bore offers 3927N push at 0.5MPa; for less, the 63mm bore provides 1559N. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve. At 900mm stroke, use external guides to prevent rod bending under side loads. The SAUF variant adds a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU80X900TC
- ✓ 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 SU80X900TC FAQ
Yes, the AirTAC SU80X900TC is discontinued. The direct replacement is the SAU80X900TC. It matches the 80mm bore, 900mm stroke, 2513N force, 3/8" port, and TC mounting. You also gain the option of the SAUF built-in-valve variant.
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 a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches, unlike the legacy CS1-B/DS1-B.
