This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X40H, 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 SU63X40H
The AirTAC Airtac SU63-100 Standard Cylinder SU63X40H is a double-acting profile-type standard cylinder with a Ø63mm bore and 40mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X40H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X40H
The AirTAC SU63X40H is a discontinued double-acting profile-type cylinder with a 63 mm bore, 40 mm stroke, and Viton H high-temperature seals rated for 0 to 150 C. Delivering 1559 N push force at 0.5 MPa through a 3/8" port, its extruded aluminum body is more compact than a same-bore ISO 15552 unit. AirTAC replaced this EOL unit with the SAU63X40H direct replacement, matching the exact bore, stroke, output force, port size, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept position sensors. The SAU upgrade retains the physical dimensions but uses modern CMSG/DMSG/EMSG switches on magnetized variants, and introduces the SAUF built-in 4M solenoid valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X40H 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 SAU63X40H 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 SU63X40H Is Used
Hot Stamp Ejection
Uses the 1559 N push force at 0.5 MPa to eject parts from heated molds, leveraging the Viton H seals to withstand 150 C ambient radiant heat.
High-Temp Diverting
Short 40 mm stroke actuates a diverting gate near industrial ovens, where the compact profile body fits tight conveyor framing without tie-rod interference.
Clamp and Release
Secures workpieces during thermal welding processes, providing repeatable clamping while the high-temp seals resist degradation from nearby heating elements.
Replacing the Airtac SU63-100 Standard Cylinder SU63X40H with the SAU63X40H
To replace the SU63X40H, order the SAU63X40H direct equivalent, verifying the 63 mm bore, 40 mm stroke, M16x1.5 rod thread, and 3/8" port. Reuse your existing AirTAC SC-series mounting accessories like LB, FA, or TC brackets. This non-magnetic SKU cannot support sensors; if you need position detection on the new SAU, add the -S option and migrate from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. If your application requires integrated flow control, explore the SAUF variant with its built-in valve. For loads needing 2182 N at 0.7 MPa, this 63 mm bore is ideal, but if you need less force, step down to a 50 mm bore. Remember, the air cushion only decelerates the piston near stroke end; it will not hold a load on air loss, so add an external rod lock or pilot-operated check valve for vertical safety. The 40 mm stroke is short, so side-load rod-bending risks are minimal.
Replacement checklist
- ✓ Same bore / stroke → SAU63X40H
- ✓ 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 SU63X40H FAQ
Yes, the SU63X40H is discontinued. The direct replacement is the AirTAC SAU63X40H. It shares the identical 63 mm bore, 40 mm stroke, 3/8" port, Viton H high-temp seals, and SC-series mounting footprint, so it bolts right in. The SAU line also adds the option for a built-in valve (SAUF) which the SU lacked.
At 0.5 MPa it provides 1559 N push and 1402 N pull force, increasing to 2182 N push at 0.7 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot accept position sensors. If sensing is required on the SAU replacement, you must order a -S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
