This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X145, 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 SU100X145
The AirTAC Airtac SU63-100 Standard Cylinder SU100X145 is a double-acting profile-type standard cylinder with a Ø100mm bore and 145mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X145, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X145
The AirTAC SU100X145 is a discontinued double-acting profile-type cylinder with a 100mm bore and 145mm stroke. Delivering 3927 N push force at 0.5 MPa, it features an extruded aluminium barrel and adjustable end cushions. The direct replacement is the SAU100X145, matching the bore, stroke, 1/2" port, and SC-series mounting.
This SAU upgrade reuses the same body profile but introduces CMSG/DMSG/EMSG sensors and an optional SAUF built-in valve. Note this base SU SKU lacks a magnet and cannot accept switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X145 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 SAU100X145 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 SU100X145 Is Used
Heavy Pressing
Applies the 3927 N push force at 0.5 MPa for seating heavy bearings or pressing large mechanical components.
Mold Clamping
Secures large injection molds using the 100mm bore power class, relying on external check valves for hold.
Replacing the Airtac SU63-100 Standard Cylinder SU100X145 with the SAU100X145
To replace the SU100X145, order the SAU100X145. Verify the 1/2" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) are retained. Because this is a non-magnet SKU, it cannot hold a sensor; if sensing is needed, specify an SAU-S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For loads needing 5497 N at 0.7 MPa, this 100mm bore is ideal, while a 80mm bore offers 3518 N. A plain cylinder drifts on air loss, so add an external rod lock for holding. The SAUF variant integrates a valve if desired.
Replacement checklist
- ✓ Same bore / stroke → SAU100X145
- ✓ 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 SU100X145 FAQ
Yes, the SU100X145 is discontinued. The direct replacement is the SAU100X145, offering identical 100mm bore, 145mm stroke, force, 1/2" port, and SC-series mounting.
It has a 1/2" port. Force outputs are 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N at 0.9 MPa, and an 801 kgf maximum at 1.0 MPa.
