This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X335, 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 SU63X335
The AirTAC Airtac SU63-100 Standard Cylinder SU63X335 is a double-acting profile-type standard cylinder with a Ø63mm bore and 335mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X335, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X335
The AirTAC SU63X335 is a discontinued double-acting profile-type cylinder with a 63mm bore and 335mm stroke. It delivers 1559N push force at 0.5MPa via a 3/8" port. The direct replacement is the SAU63X335, matching the bore, stroke, output force, and SC-series mounting.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors, unlike this legacy unit. This SKU lacks a magnet and cannot take a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X335 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 SAU63X335 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 SU63X335 Is Used
Package Diversion
Pushes heavy cartons at 90 degrees on a sorting line using the 1559N push force, with the 335mm stroke clearing adjacent lanes.
Pallet Stopper
Acts as a pneumatic stop for inbound pallets, absorbing kinetic energy via the adjustable cushions before downstream processing.
Press Ejection
Ejects formed metal parts from a press bed, requiring the 1402N pull force to retract the 20mm rod through the 335mm cycle.
Replacing the Airtac SU63-100 Standard Cylinder SU63X335 with the SAU63X335
To replace this discontinued SU63X335, order the SAU63X335 direct equivalent. Confirm the 3/8" port, M16x1.5 rod thread, and SC-series mounting. Because this is a non-magnet SKU, it cannot accept a sensor. If sizing alternatives, the 50mm bore yields 982N push while the 80mm yields 2513N at 0.5MPa. For the 335mm stroke, use external guides to prevent rod bending from side loads. Note that air cushions only decelerate; use an external rod lock or pilot-operated check valve to hold loads. The SAUF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X335
- ✓ 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 SU63X335 FAQ
Yes, the SU63X335 is discontinued. The direct replacement is the SAU63X335, offering the same 63mm bore, 335mm stroke, force, 3/8" port, and SC-series mounting compatibility.
It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf max at 1.0MPa. This specific SKU has no magnet and cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
