This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X400H, 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 SU80X400H
The AirTAC SU63-100 Standard Cylinder SU80X400H is a double-acting profile-type standard cylinder with a Ø80mm bore and 400mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X400H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X400H
The AirTAC SU80X400H is a discontinued double-acting profile cylinder with an extruded aluminium barrel and a 400 mm stroke. As a high-temperature variant, it uses Viton H seals to operate up to 150 C. Generating 2513 N push force at 0.5 MPa, its direct replacement is the SAU80X400H, which matches the 80 mm bore, 25 mm rod, 3/8 inch port, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade retains the physical footprint but uses modern CMSG/DMSG/EMSG switches, and introduces the SAUF built-in valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X400H 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 SAU80X400H 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 SU80X400H Is Used
High-Temperature Ejection
Ejecting molded parts from hot environments using the Viton H seal rated for 150 C, delivering 2513 N push force at 0.5 MPa.
400mm Linear Actuation
Driving heavy 400 mm linear traversing motions where the 80 mm bore and 3/8 inch port provide stable airflow for industrial handling.
Replacing the Airtac SU63-100 Standard Cylinder SU80X400H with the SAU80X400H
To replace this discontinued SU80X400H, order the SAU80X400H direct equivalent, verifying the 80 mm bore, 400 mm stroke, 3/8 inch port, M20x1.5 rod thread, and SC-series mounting. If sizing alternatives, the adjacent 63 mm bore yields 1559 N push while the 100 mm bore reaches 3927 N at 0.5 MPa. This cylinder is double-acting with a 30-800 mm/s speed range. A plain cylinder does not hold load without live air; use an external rod lock or pilot-operated check valve for holding. The cushion only decelerates near stroke end. At 400 mm, prevent rod bending by supporting the load with an external guide. The Viton H seal supports 0-150 C.
Replacement checklist
- ✓ Same bore / stroke → SAU80X400H
- ✓ 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 SU80X400H FAQ
Yes, the AirTAC SU80X400H is discontinued. The direct replacement is the SAU80X400H, which offers the same 80 mm bore, 400 mm stroke, 2513 N push force at 0.5 MPa, 3/8 inch port, and SC-series mounting compatibility.
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 and cannot take a sensor; the SAU replacement supports CMSG/DMSG/EMSG switches.
