This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X75STC, 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 SU100X75STC
The AirTAC Airtac SU63-100 Standard Cylinder SU100X75STC 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 SAU100X75STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X75STC
The AirTAC SU100X75STC is a discontinued double-acting profile-type cylinder with a 100 mm bore and 75 mm stroke, delivering 3927 N push force at 0.5 MPa. The direct replacement is the SAU100X75STC, which preserves the exact bore, stroke, output force, 1/2" port, and SC-series mounting interface.
This compact extruded-aluminium body is shorter than an ISO 15552 cylinder of the same bore. The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches, and adds the SAUF built-in-valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X75STC 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 SAU100X75STC 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 SU100X75STC Is Used
Heavy Press Ejection
Provides the high push force needed to eject dense metal stampings from a hydraulic press bed.
Pallet Diversion
Uses the TC mount and 75 mm stroke to push heavy loaded pallets onto a secondary packaging line.
Bulk Container Gating
Actuates a heavy physical gate to control the flow of bulk material totes at a distribution hub.
Replacing the Airtac SU63-100 Standard Cylinder SU100X75STC with the SAU100X75STC
To replace this SU100X75STC, order the SAU100X75STC and confirm the 100 mm bore, 75 mm stroke, 1/2" port, M20x1.5 rod thread, and TC mounting. The built-in magnet (-S) means you must switch from the old CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. If sizing alternatives, a neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore hits 5497 N at 0.7 MPa. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated option can simplify actuation if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU100X75STC
- ✓ 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 SU100X75STC FAQ
Yes, the SU100X75STC is discontinued. The direct replacement is the SAU100X75STC, matching the 100 mm bore, 75 mm stroke, force, 1/2" port, and TC mounting.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 801 kgf max at 1.0 MPa. The -S magnet used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
