This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X85S, 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 Airtac SU63-100 Standard Cylinder SU100X85S is a double-acting profile-type standard cylinder with a Ø100mm bore and 85mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X85S, which matches its bore, stroke, force and mounting.
The AirTAC SU100X85S is a discontinued double-acting profile-type cylinder with an 85mm stroke and 100mm bore, delivering 3927N push and 3681N pull at 0.5MPa. The direct replacement is the SAU100X85S, matching the 1/2in port, M20x1.5 rod thread, force and SC-series mounts exactly. Note that 85mm is a nonstandard stroke.
The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X85S 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 SAU100X85S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 100 | Bore size in mm. |
| ×85 | Stroke length in mm. |
| -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.
Provides the robust 3927N push force required to eject dense metal stampings from a hydraulic press bed.
Raises and lowers heavy loaded pallet gates, safely moving approximately 200kg vertical loads per cylinder.
Secures large injection mold halves with high holding energy, relying on 1/2in ports for rapid actuation.
To replace this SU100X85S, order the SAU100X85S direct equivalent, keeping the 100mm bore, 85mm nonstandard stroke, 1/2in port, and SC-series mounting hardware. If sizing alternatives, the neighbouring 80mm bore yields 2513N push at 0.5MPa, while the 100mm bore hits 5497N at 0.7MPa. Because this is a nonstandard 85mm stroke, confirm delivery times. A plain cylinder drifts on air loss since the 29mm adjustable cushion only decelerates; use an external rod lock or pilot-operated check valve for held loads. The -S magnet means your old CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU. For self-switching needs, consider the SAUF valve-integrated variant.
Replacement checklist
Yes, the SU100X85S is discontinued. The direct replacement is the SAU100X85S. It matches the 100mm bore, 85mm stroke, 1/2in port, output force, and SC-series mounting accessories. You can install the SAU directly into the same application.
The 100mm bore yields 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and a theoretical max of 801kgf at 1.0MPa. The -S suffix means it has a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades these to current CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU100X85S replacement — usually within 7-8 hours.
