This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X260, 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 SU63X260
The AirTAC Airtac SU63-100 Standard Cylinder SU63X260 is a double-acting profile-type standard cylinder with a Ø63mm bore and 260mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X260, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X260
The AirTAC SU63X260 is a discontinued double-acting profile-type cylinder with a 63mm bore and 260mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, utilizing a 3/8 inch port and a 20mm piston rod with M16x1.5 threading. AirTAC replaced this end-of-line unit with the SAU63X260, a direct alternative retaining the exact profile body, force output, and SC-series mounting footprint.
Because this specific SKU lacks a magnet, it cannot accept any position sensors. Upgrading to the SAU63X260 allows you to add current CMSG/DMSG/EMSG switches if needed, and opens up the SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X260 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 SAU63X260 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU63-100 Standard Cylinder SU63X260 Is Used
Mid-Range Package Diversion
Provides the 1559N push force needed to actuate heavy-duty routing gates on high-speed packaging lines without overshooting.
Pallet Component Staging
Offers a compact 260mm stroke to push standardized totes or sub-assemblies into position at workstation loading zones.
Clamp Actuation
Delivers reliable holding pressure for medium-weight aluminum fixture clamps during automated machining cycles.
Replacing the Airtac SU63-100 Standard Cylinder SU63X260 with the SAU63X260
To replace this discontinued SU63X260, order the SAU63X260 and verify your 3/8 inch port thread (PT, G, or NPT) alongside your SC-series mounting hardware. Since this original SKU has no magnet, it cannot hold a switch; the SAU replacement allows adding CMSG/DMSG/EMSG sensors. If comparing neighbouring bores, a 50mm bore yields 982N push at 0.5MPa while an 80mm bore yields 2513N, so the 63mm at 1559N is optimal for mid-range loads. Note that a plain cylinder drifts without live air—the cushions only decelerate near stroke ends—so use an external rod lock or pilot-operated check valve for secure load holding. At 260mm stroke, side-load and rod-bending forces are moderate, so ensure adequate guide alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAU63X260
- ✓ 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 SU63X260 FAQ
Yes, the SU63X260 is discontinued. The direct replacement is the AirTAC SAU63X260. It matches the 63mm bore, 260mm stroke, 3/8 inch port, output force, and SC-series mounting accessories perfectly, so no mechanical redesign is required.
The 63mm bore generates 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. Because this specific SU63X260 SKU lacks a magnet, it cannot accept legacy CS1-B/DS1-B switches; the SAU replacement supports modern CMSG/DMSG/EMSG sensors.
