This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X75, 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 SU100X75
The AirTAC Airtac SU63-100 Standard Cylinder SU100X75 is a double-acting profile-type standard cylinder with a Ø100mm bore and 75mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X75, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X75
The AirTAC SU100X75 is a discontinued double-acting profile cylinder featuring a 100mm bore and 75mm stroke. Delivering 3927 N push force at 0.5 MPa, it uses an extruded aluminum barrel that is more compact than a same-bore ISO 15552 unit. AirTAC replaced this end-of-life unit with the SAU100X75 direct replacement, preserving the exact 1/2" port, M20x1.5 rod thread, output force, and SC-series mounting footprint.
Because this specific SKU lacks a magnet (-S), it cannot accept position sensors. The SAU upgrade modernizes sensing by using CMSG/DMSG/EMSG switches on magnetized variants, and introduces the SAUF built-in 4M valve option absent from the original SU line.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X75 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X75 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 SU100X75 Is Used
Heavy Stamping Press
Drives heavy-duty stamping and forming dies requiring substantial push force over a short 75mm travel distance.
Pallet Redirector
Actuates robust routing gates on high-capacity conveyor lines, easily handling the inertia of loaded pallets.
Mold Clamping Station
Secures large injection molds or heavy industrial fixtures during processing using its 200 kg vertical lift capability.
Replacing the Airtac SU63-100 Standard Cylinder SU100X75 with the SAU100X75
To replace the SU100X75, order the SAU100X75. Verify your 1/2" port (PT/G/NPT) and SC-series mounting (LB/FA/FB/CA/CB). Since this non-magnetic SKU cannot hold a sensor, order an SAU100X75S if you need switches (note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG). For load holding, add an external rod lock or pilot-operated check valve, as cushions only decelerate. If downsizing, a 80mm bore yields 2513 N push at 0.5 MPa; if upsizing, note the 100mm bore already hits 5497 N at 0.7 MPa. Consider the SAUF variant for integrated valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU100X75
- ✓ 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 SU100X75 FAQ
Yes, the SU100X75 is discontinued. The direct replacement is the AirTAC SAU100X75. It matches the original 100mm bore, 75mm stroke, 1/2" port, output force, and SC-series mounting accessories, so it fits the same application directly.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept position switches; the SAU replacement uses CMSG/DMSG/EMSG sensors on its -S variants.
