This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X625, 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 SU80X625
The AirTAC SU63-100 Standard Cylinder SU80X625 is a double-acting profile-type standard cylinder with a Ø80mm bore and 625mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X625, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X625
The AirTAC SU80X625 is a discontinued double-acting profile-type cylinder with an 80mm bore and 625mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, operating at 30-800mm/s through a 3/8" port. AirTAC replaced this unit with the SAU80X625, a direct sharing the exact body, force, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches, and adds the SAUF built-in-valve option. This SKU lacks a magnet, so it cannot accept switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X625 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 SAU80X625 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 SU80X625 Is Used
Heavy Conveyor Diverting
Drives large heavy-duty diverters on packaging lines, using the 2513N push force at 0.5MPa to reliably push heavy cartons off the main belt.
Pallet Stopper Gate
Acts as a robust pneumatic stop for pallets entering a wrapper, where the 625mm stroke extends across the lane and the compact profile saves floor space.
Material Press Fixture
Provides consistent clamping pressure for holding large composite panels during secondary machining, safely operating within the 1508N working load limit.
Replacing the Airtac SU63-100 Standard Cylinder SU80X625 with the SAU80X625
To replace the SU80X625, order the SAU80X625. Verify your 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU has no magnet (-S), it cannot support sensing; if you need position detection, specify an SAU80X625S and migrate to CMSG/DMSG/EMSG switches. The SAU family also offers the SAUF variant with a built-in 4M solenoid valve. For sizing, a 63mm bore provides 1559N [email protected], while a 100mm bore yields 3927N. With a 625mm stroke, use external guides to prevent rod bending and side-load damage. Note that a plain cylinder drifts on air loss; the 28mm cushions only decelerate near stroke end, so use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X625
- ✓ 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 SU80X625 FAQ
Yes, the SU80X625 is discontinued. The direct replacement is the AirTAC SAU80X625. It shares the identical 80mm bore, 625mm stroke, 3/8" port, output force, and SC-series mounting, so it fits the same application without modifications.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a theoretical max of 513kgf at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept magnetic switches; the SAU replacement uses CMSG/DMSG/EMSG sensors.
