This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X950, 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 SU80X950
The AirTAC SU63-100 Standard Cylinder SU80X950 is a double-acting profile-type standard cylinder with a Ø80mm bore and 950mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X950, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X950
The AirTAC SU80X950 is a discontinued double-acting profile-type cylinder with an 80mm bore and 950mm stroke. Delivering 2513N push and 2268N pull at 0.5MPa, its extruded aluminum barrel is more compact than an ISO 15552 unit of the same size. AirTAC replaced it with the SAU80X950, a direct upgrade retaining the exact bore, stroke, output force, 3/8 inch port, and SC-series mounting.
This non-magnetic SKU cannot accept a sensor, whereas the SAU upgrade supports modern CMSG/DMSG/EMSG switches (the SU line used legacy CS1-B/DS1-B). Note that a standard cylinder drifts without live air; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X950 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 SAU80X950 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 SU80X950 Is Used
Pallet Diversion
Pushes heavy pallets off a main conveyor line using 2513N of thrust at 0.5MPa, with the 950mm stroke clearing wide transfer zones.
Long-Stroke Ejection
Ejects molded parts from deep press beds, utilizing the 28mm adjustable air cushions at both ends to decelerate the 25mm rod smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X950 with the SAU80X950
To replace the discontinued SU80X950, order the SAU80X950 direct equivalent, verifying your 3/8 inch port threads (PT, G, or NPT) and SC-series mounting hardware. Because this 950mm stroke exceeds typical compact lengths, add external guide rails to prevent rod bending and premature seal wear under side loads. If downsizing is possible, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore provides 3927N. This non-magnetic version cannot take switches, but if you need position sensing, the SAU replacement requires CMSG/DMSG/EMSG sensors rather than the old CS1-B/DS1-B. For holding loads mid-stroke, add a pilot-operated check valve, as cushions only decelerate at end-of-travel. The SAUF variant also offers a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU80X950
- ✓ 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 SU80X950 FAQ
Yes, the AirTAC SU80X950 is discontinued and end-of-life. The direct replacement is the SAU80X950. It shares the identical 80mm bore, 950mm stroke, output force, 3/8 inch port, and SC-series mounting accessories, so it fits the same application without modification.
This double-acting cylinder has a 3/8 inch port and a 25mm piston rod. It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical maximum of 513kgf at 1.0MPa. It operates at 30-800mm/s.
