This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X175, 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 SU80X175
The AirTAC SU63-100 Standard Cylinder SU80X175 is a double-acting profile-type standard cylinder with a Ø80mm bore and 175mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X175, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X175
The AirTAC SU80X175 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 175 mm stroke. Delivering 2513 N push force at 0.5 MPa, it features an extruded aluminium barrel that is more compact than an ISO 15552 cylinder of the same size. The direct replacement is the SAU80X175, matching the 2513 N force, 3/8" port, M20x1.5 rod thread and SC-series mounting.
This non-magnetic SKU cannot accept a sensor. The SAU upgrade adds current CMSG/DMSG/EMSG switch compatibility (the SU used legacy CS1-B/DS1-B) and a SAUF built-in 4M valve option. Note that air cushions only decelerate; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X175 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 SAU80X175 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 SU80X175 Is Used
Package Diverting
Actuates diverting arms on 3/8" port pneumatic lines to push 128 kg packed cartons off a main conveyor belt at high speed.
Pallet Stopping
Deploys a heavy-duty end-stop to halt loaded pallets, using the 2513 N push force at 0.5 MPa to absorb kinetic energy safely.
Press Ejection
Ejects formed metal components from a press bed, utilising the 175 mm stroke and 2268 N pull force to retract the tooling cleanly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X175 with the SAU80X175
To replace the SU80X175, order the SAU80X175 direct equivalent, verifying the 3/8" port, M20x1.5 thread, 28 mm cushions, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU lacks a magnet (-S), it cannot support sensing; if position detection is needed, specify an SAU80X175S and switch to CMSG/DMSG/EMSG sensors. Sizing both ways: dropping to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to 100 mm provides 3927 N. For automated valve control, consider the SAUF80X175 variant with its integrated solenoid. Remember, a standard cylinder drifts without live air—install a pilot-operated check valve for load holding. At 175 mm stroke, rod bending is low, but always guide the load to prevent side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU80X175
- ✓ 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 SU80X175 FAQ
Yes, the SU80X175 is discontinued. The direct replacement is the AirTAC SAU80X175. It shares the same 80 mm bore, 175 mm stroke, 2513 N output force, 3/8" port, and SC-series mounting accessories, so it fits the same application without mechanical modifications.
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 maximum theoretical force of 513 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor. If sensing is required, order the SAU80X175S replacement, which uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
