This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X65, 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 SU80X65
The AirTAC Airtac SU63-100 Standard Cylinder SU80X65 is a double-acting profile-type standard cylinder with a Ø80mm bore and 65mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X65, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X65
The AirTAC SU80X65 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 65 mm stroke. It delivers 2513 N of push force at 0.5 MPa through a 3/8 inch port. AirTAC replaced this legacy unit with the SAU80X65, a direct alternative retaining the exact same bore, stroke, output force, port size, and SC-series mounting footprint.
Because this is a non-magnet SKU, it cannot accept position sensors. The SAU upgrade also drops the legacy CS1-B/DS1-B switches for modern CMSG/DMSG/EMSG sensors. The SAU line additionally introduces the SAUF variant featuring a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X65 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 SAU80X65 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 SU80X65 Is Used
Press Fit Assembly
Drives bearings or pins into housings, utilizing the 2513 N push force at 0.5 MPa for reliable insertion without overstressing components.
Pallet Diversion
Actuates heavy diverting arms on packaging lines to redirect loaded pallets, taking advantage of the compact 80 mm profile body.
Gate Operation
Opens and closes heavy security or access gates on automated storage systems, where the 128 kg vertical lift margin handles the weight easily.
Replacing the Airtac SU63-100 Standard Cylinder SU80X65 with the SAU80X65
To replace this discontinued SU80X65, order the SAU80X65 direct equivalent, verifying your 3/8 inch port threads (PT, G, or NPT) and SC-series mounting hardware. Since this specific SKU lacks a magnet, it cannot hold a sensor; if you require position detection on the new unit, you must select an SAU80X65-S and use CMSG/DMSG/EMSG switches. For loads needing 3518 N at 0.7 MPa, this 80 mm bore is correct, but if your application only requires 1374 N, stepping down to a 50 mm bore saves space and air. Note that a standard cylinder drifts without live air—the cushions only decelerate the piston—so fit an external rod lock or pilot-operated check valve for secure load holding. At 65 mm stroke, side-load risks are minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same bore / stroke → SAU80X65
- ✓ 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 SU80X65 FAQ
Yes, the SU80X65 is discontinued. The direct replacement is the AirTAC SAU80X65. It matches the 80 mm bore, 65 mm stroke, 2513 N force, 3/8 inch port, and SC-series mounting, so it drops right into the same application.
The 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Because this specific SKU has no magnet, it cannot accept sensors; the SAU replacement with a magnet uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
