This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X650STC, 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 SU80X650STC
The AirTAC Airtac SU63-100 Standard Cylinder SU80X650STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 650mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X650STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X650STC
The AirTAC SU80X650STC is a discontinued double-acting profile-type cylinder with an 80mm bore and 650mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, operating at 30-800mm/s through a 3/8" port. The direct replacement is the SAU80X650STC, matching the bore, stroke, force, and TC mounting exactly.
The SAU upgrade switches the -S magnet to modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B, and introduces the SAUF built-in-valve option. The 650mm stroke requires external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X650STC 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 SAU80X650STC 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 SU80X650STC Is Used
Pallet Diversion
Pushes heavy pallets laterally across transfer lines using the 2513N push force, while the TC mount handles the rotational moment during transit.
Press Ejection
Ejects dense stamped parts from machinery beds, relying on adjustable end cushions to decelerate the 25mm rod before impact.
Replacing the Airtac SU63-100 Standard Cylinder SU80X650STC with the SAU80X650STC
To replace this SU80X650STC, order the SAU80X650STC keeping the 80mm bore, 650mm stroke, 3/8" port, M20x1.5 rod thread, and TC mounting. If sizing alternatives, a 63mm bore gives 1559N push at 0.5MPa while a 100mm bore yields 3927N. Because the 650mm stroke is long, add external guides to prevent rod bending. The -S magnet requires changing legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate; use an external rod lock or pilot-operated check valve to hold loads, or consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X650STC
- ✓ 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 SU80X650STC FAQ
Yes, the SU80X650STC is discontinued. The direct replacement is the SAU80X650STC, which shares the same 80mm bore, 650mm stroke, 3/8" port, and TC mounting. You must upgrade any -S magnet sensors from the old CS1-B/DS1-B to the current CMSG/DMSG/EMSG family.
At 0.5MPa it provides 2513N push and 2268N pull; at 0.7MPa push is 3518N; at 0.9MPa push is 4523N; and the theoretical maximum is 513kgf at 1.0MPa. The cylinder does not hold load without live air, so an external rod lock is needed for holding.
