This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X20H, 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.

The AirTAC SU63-100 Standard Cylinder SU100X20H is a double-acting profile-type standard cylinder with a Ø100mm bore and 20mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X20H, which matches its bore, stroke, force and mounting.
The AirTAC SU100X20H is a discontinued double-acting profile-type cylinder with a 100mm bore and 20mm stroke. As a high-temperature variant, it uses Viton H (FKM) seals to operate up to 150C, while delivering 3927 N of push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAU100X20H, a direct upgrade retaining the exact 1/2 inch port, M20x1.5 rod thread, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept position sensors. The SAU replacement modernizes sensing with CMSG/DMSG/EMSG switches, and also introduces the SAUF valve-integrated option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X20H carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X20H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Applies 3927 N of clamping force on heated molds using Viton H seals rated for 150C environments.
Drives heavy-duty process valves with a robust 25mm rod, relying on the 1/2 inch port for rapid airflow.
To replace this SU100X20H, order the SAU100X20H. Verify your 1/2 inch port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC) which carry over directly. Since this high-temp Viton H cylinder has no magnet (-S), it cannot use legacy CS1-B/DS1-B switches; if you need sensing on the new SAU, you must specify a magnet and use current CMSG/DMSG/EMSG sensors. If your application requires holding a load without live air, add an external rod lock or pilot-operated check valve, as the adjustable 29mm cushions only decelerate near stroke end. For higher force demands, the 80mm bore offers 2513 N push at 0.5 MPa, while staying within the 30-800 mm/s speed range.
Replacement checklist
Yes, the AirTAC SU100X20H is discontinued. The direct replacement is the SAU100X20H. It shares the same 100mm bore, 20mm stroke, 1/2 inch port, output force, and SC-series mounting, so it fits your existing application directly.
At 0.5 MPa it provides 3927 N push and 3681 N pull force, scaling to 5497 N 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 supports CMSG/DMSG/EMSG sensors when ordered with the -S magnet option.
