This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X85, 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 SU80X85
The AirTAC Airtac SU63-100 Standard Cylinder SU80X85 is a double-acting profile-type standard cylinder with a Ø80mm bore and 85mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X85, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X85
The AirTAC SU80X85 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 85 mm stroke. It delivers 2513 N push force at 0.5 MPa and features a 25 mm piston rod with M20x1.5 threads and a 3/8" port. AirTAC replaced this EOL unit with the SAU80X85, a direct replacement retaining the exact same body dimensions, force, port size, and SC-series mounting accessories.
Buyers upgrading to the SAU80X85 gain compatibility with modern CMSG/DMSG/EMSG sensors, whereas this legacy SU used CS1-B/DS1-B switches. Because this specific SKU lacks a magnet, it cannot accept any sensor. The extruded aluminum profile is more compact than a same-bore ISO 15552 unit.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X85 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 SAU80X85 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 SU80X85 Is Used
Heavy-Duty Clamping
Secures large steel fabrications during welding or machining, utilizing the 2513 N push force at 0.5 MPa to hold rigid workpieces firmly in place.
Pallet Diverting
Actuates heavy diverting arms on packaging lines, providing the robust 80 mm bore output needed to push fully loaded pallets onto secondary tracks.
Carton Ejection
Ejects dense or heavy product cartons from sorting conveyors, where the 128 kg vertical lift capacity and compact profile body fit neatly into tight transfer spaces.
Replacing the Airtac SU63-100 Standard Cylinder SU80X85 with the SAU80X85
To replace the discontinued SU80X85, order the SAU80X85, confirming the 80 mm bore, 85 mm stroke, 3/8" port, and M20x1.5 rod thread. If stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa (close to this unit's 2513 N), while an 100 mm bore provides 3927 N. Since this non-magnetic SKU cannot take a switch, order an SAU80X85-S if you need position sensing, noting you must migrate to CMSG/DMSG/EMSG switches. The SAUF variant offers a built-in 4M valve the SU lacked. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. At 85 mm stroke, rod bending is minimal, but always guide the load to prevent side-loading.
Replacement checklist
- ✓ Same bore / stroke → SAU80X85
- ✓ 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 SU80X85 FAQ
Yes, the AirTAC SU80X85 is discontinued. The direct replacement is the SAU80X85. It matches the 80 mm bore, 85 mm stroke, 3/8" port, 25 mm rod, and SC-series mounting hardware. You also gain the option of the SAUF built-in valve variant.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. Because this specific SKU has no magnet (-S), it cannot accept sensors; the SAU-S replacement uses CMSG/DMSG/EMSG switches.
