This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X25H, 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 SU80X25H
The AirTAC SU63-100 Standard Cylinder SU80X25H is a double-acting profile-type standard cylinder with a Ø80mm bore and 25mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X25H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X25H
The AirTAC SU80X25H is a discontinued double-acting profile-type cylinder featuring an extruded aluminum barrel and adjustable air cushions at both ends. Designed for high-temperature environments, the -H seal option utilizes Viton FKM to operate reliably from 0 to 150 degrees Celsius.
AirTAC replaced this end-of-life unit with the SAU80X25H, a direct replacement retaining the exact 80 mm bore, 25 mm stroke, 3/8 inch port, and SC-series mounting. The upgrade introduces current CMSG/DMSG/EMSG sensors and a new SAUF built-in-valve variant the SU line lacked. Note this specific SKU lacks a magnet and cannot accept sensing switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X25H carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X25H 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 SU80X25H Is Used
Hot Stamp Ejection
Short 25 mm stroke pushes finished parts from heated dies, leveraging the Viton seal to withstand ambient temperatures up to 150 degrees Celsius without degrading.
High-Temp Diverting
Actuates diverter arms near ovens or thermal tunnels where standard NBR seals would fail, providing 2513 N of thrust to redirect heavy packages.
Clamping in Foundries
Secures castings for machining operations in hot environments, using its robust 80 mm profile body to deliver firm 1508 N safe working clamping force.
Replacing the Airtac SU63-100 Standard Cylinder SU80X25H with the SAU80X25H
To replace the discontinued SU80X25H, order the SAU80X25H, confirming the 80 mm bore, 25 mm stroke, 3/8 inch port, M20x1.5 rod thread, and SC-series mounting accessories. Because this high-temp Viton cylinder has no magnet (-S), it cannot support position sensing; if switches are needed, specify an SAU magnet option and migrate to CMSG/DMSG/EMSG sensors. For force sizing, the 80 mm bore yields 2513 N push at 0.5 MPa, while the neighboring 63 mm bore offers 1559 N. Remember that a standard cylinder drifts without live air—the cushion only decelerates—so install an external rod lock or pilot-operated check valve for load holding. The SAUF valve-integrated variant is also available if compact self-switching is desired.
Replacement checklist
- ✓ Same bore / stroke → SAU80X25H
- ✓ 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 SU80X25H FAQ
Yes, the AirTAC SU80X25H is discontinued. The direct replacement is the SAU80X25H, which matches the 80 mm bore, 25 mm stroke, 3/8 inch port, output force, and SC-series mounting. You simply order the SAU equivalent.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot accept legacy CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors if sensing is added.
