This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X205, 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 SU80X205
The AirTAC Airtac SU63-100 Standard Cylinder SU80X205 is a double-acting profile-type standard cylinder with a Ø80mm bore and 205mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X205, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X205
The AirTAC SU80X205 is a discontinued double-acting profile-type cylinder with an 80mm bore and 205mm stroke. As a nonstandard stroke, it requires precise sizing, delivering 2513N push and 2268N pull at 0.5MPa. AirTAC replaced this EOL unit with the SAU80X205, a direct alternative retaining the exact 3/8 port, M20x1.5 rod thread, and SC-series mounting footprint.
This extruded aluminum barrel is shorter than an ISO 15552 equivalent. Since this SKU lacks a magnet, it cannot accept sensors; the SAU upgrade uses CMSG/DMSG/EMSG switches, and adds a SAUF built-in-valve option. Note the cushion only decelerates; use a rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X205 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 SAU80X205 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 SU80X205 Is Used
Mid-Tonnage Stamping
Ideal for driving medium-tonnage stamping or riveting presses, utilizing the 2513N push force at 0.5MPa to form components reliably.
Heavy Package Diverting
Actuates heavy-duty diverter arms on packaging lines, where the 205mm stroke provides the reach needed to redirect large cartons.
Replacing the Airtac SU63-100 Standard Cylinder SU80X205 with the SAU80X205
To replace this discontinued SU80X205 with the SAU80X205, verify your 80mm bore, 205mm stroke, 3/8 port, and SC-series mounting. This nonstandard 205mm stroke requires checking side-load limits; use guide rails to prevent rod bending. Sizing both ways: a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. Without a -S magnet, this SKU cannot take a sensor. For load holding on air loss, add an external rod lock, as cushions only decelerate. The SAUF valve-integrated variant is available if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X205
- ✓ 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 SU80X205 FAQ
Yes, the SU80X205 is discontinued. The direct replacement is the AirTAC SAU80X205, matching the 80mm bore, 205mm stroke, 3/8 port, and SC-series mounting.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a max of 513kgf at 1.0MPa. This non-magnetic SKU cannot take sensors; the SAU replacement uses CMSG/DMSG/EMSG switches.
