This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X85, 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 SU100X85
The AirTAC SU63-100 Standard Cylinder SU100X85 is a double-acting profile-type standard cylinder with a Ø100mm bore and 85mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X85, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X85
The AirTAC SU100X85 is a discontinued double-acting profile-type cylinder with an 85mm stroke. Delivering 3927N push force at 0.5MPa, it uses a 25mm piston rod and a 1/2in port. The direct replacement is the SAU100X85, matching the bore, stroke, force, port and SC-series mounting.
This extruded aluminium body is more compact than an ISO 15552 equivalent. The SAU upgrade switches to CMSG/DMSG/EMSG sensors and adds a SAUF valve option. This non-magnet SKU takes no switch, and air cushions only decelerate, so use a rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X85 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X85 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 SU100X85 Is Used
Heavy Press Clamping
Ideal for securing heavy metal components during machining, using its 3927N push force at 0.5MPa to hold parts firmly in jigs.
Pallet Load Shifting
Provides the robust thrust needed to push loaded pallets or heavy containers across transfer lines in logistics hubs.
Stamping Ejection
Delivers reliable ejection force to push finished stamped parts out of heavy-duty presses in manufacturing plants.
Replacing the Airtac SU63-100 Standard Cylinder SU100X85 with the SAU100X85
To replace the SU100X85, order the SAU100X85. Confirm the 1/2in port, M20x1.5 rod thread and PT thread type. This non-magnet SKU cannot accept a sensor; if you previously used an -S variant, the SAU uses CMSG/DMSG/EMSG switches instead of CS1-B/DS1-B. If you need integrated control, the SAUF variant offers a built-in valve. A plain cylinder drifts on air loss, so add an external rod lock for holding. At 85mm stroke, side-load is minimal, but sizing down to an 80mm bore (2513N push at 0.5MPa) or up to a 100mm bore (3927N) depends on your load.
Replacement checklist
- ✓ Same bore / stroke → SAU100X85
- ✓ 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 SU100X85 FAQ
Yes, the AirTAC SU100X85 is discontinued. The direct replacement is the SAU100X85. It matches the 100mm bore, 85mm stroke, 3927N output force, 1/2in port and SC-series mounting accessories exactly.
It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and a maximum theoretical force of 801kgf at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
