This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X235, 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 SU63X235
The AirTAC Airtac SU63-100 Standard Cylinder SU63X235 is a double-acting profile-type standard cylinder with a Ø63mm bore and 235mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X235, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X235
The AirTAC SU63X235 is a discontinued double-acting profile-type cylinder featuring a 63mm bore and 235mm stroke. Built with an extruded aluminum barrel and adjustable air cushions at both ends, it delivers 1559N push force at 0.5MPa via a 3/8" port. The direct replacement is the SAU63X235, preserving the original body, stroke, output force, and SC-series mounting footprint.
Because this stroke exceeds the 1500mm standard maximum, 235mm is a nonstandard stroke. Note this SKU lacks a magnet, so it cannot accept sensors; if upgrading to an SAU-S, switches change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG. The SAU family also adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X235 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 SAU63X235 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 SU63X235 Is Used
Package Diversion
Actuates routing gates on 3/8" ported lines to redirect 79kg palletized goods with reliable 1559N push force.
Vertical Lift Stops
Controls intermediate stopping positions on 235mm stroke lifts, requiring external check valves to hold loads safely.
Replacing the Airtac SU63-100 Standard Cylinder SU63X235 with the SAU63X235
To replace this SU63X235, order the SAU63X235 direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. Since this is a nonstandard 235mm stroke, confirm availability. If sizing alternatives, the neighboring 50mm bore yields 982N push while the 80mm provides 2513N at 0.5MPa. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. For faster cycling, explore the SAUF variant with its built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X235
- ✓ 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 SU63X235 FAQ
Yes, the AirTAC SU63X235 is discontinued. The direct replacement is the SAU63X235, matching the 63mm bore, 235mm stroke, 1559N force, 3/8" port, and SC-series mounting.
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, meaning it cannot accept sensors; upgrading to an SAU-S changes switches from CS1-B/DS1-B to CMSG/DMSG/EMSG.
