This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X125, 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 SU80X125
The AirTAC SU63-100 Standard Cylinder SU80X125 is a double-acting profile-type standard cylinder with a Ø80mm bore and 125mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X125, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X125
The AirTAC SU80X125 is a discontinued double-acting profile-type cylinder with an 80mm bore and 125mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, utilizing a 25mm rod and 3/8" port. The direct replacement is the SAU80X125, matching the body, force, and SC-series mounting.
Because it lacks a magnet, this specific SKU cannot accept a sensor. The SAU upgrade switches to CMSG/DMSG/EMSG switches for -S variants, and introduces the SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X125 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 SAU80X125 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 SU80X125 Is Used
Press Fit Assembly
Applies the 2513N push force at 0.5MPa to seat bearings and pins in automated machining lines without requiring a full hydraulic press.
Pallet Diverting
Uses the 125mm stroke to push heavy product pallets off a main conveyor belt, leveraging the compact profile to fit tight transfer spaces.
Carton Stacking
Lifts packaging cartons up to the 128kg vertical lift limit, relying on the adjustable 28mm air cushions to decelerate the 80mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X125 with the SAU80X125
To replace the SU80X125, order the SAU80X125, confirming the 80mm bore, 125mm stroke, 3/8" port, and M20x1.5 rod thread. Since this is a non-magnet SKU, it cannot take a sensor; if sensing is needed, order an -S SAU and note the switch family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If you need integrated flow control, the SAUF variant adds a built-in valve. Downsize to a 63mm bore (1559N [email protected]) for lighter loads, or upsize to 100mm (3927N) for heavier ones. This cylinder will not hold a load without air; use an external rod lock for safety.
Replacement checklist
- ✓ Same bore / stroke → SAU80X125
- ✓ 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 SU80X125 FAQ
Yes, the AirTAC SU80X125 is discontinued. The direct replacement is the SAU80X125. It provides the same 80mm bore, 125mm stroke, 3/8" port, output force, and SC-series mounting compatibility.
It provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf maximum at 1.0MPa. This specific SKU has no magnet, so it cannot accept a sensor; the SAU -S variant uses CMSG/DMSG/EMSG switches.
