This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD100X175, 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 SUD Series Double Rod Cylinder SUD100X175 is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD100X175, which matches its bore, stroke, force and mounting.
The AirTAC SUD100X175 is a double-acting, double-rod profile cylinder that is officially discontinued. The direct replacement is the SAUD100X175, matching the 100mm bore, 175mm stroke, 1/2" port, and mounting. A rod exits both ends on one piston, meaning push and pull force are equal at 3681N @0.5 MPa, 5153N @0.7 MPa, and 6626N @0.9 MPa. The extruded aluminium barrel is shorter than an ISO 15552 cylinder of the same bore.
This configuration provides anti-rotation stability and lets the back rod drive a second tool. Note this non-magnetic SKU cannot take a sensor. The air cushion only decelerates near stroke end; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X175 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X175 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.
Drives two opposing tools simultaneously from a single piston, ensuring perfectly synchronized clamping and milling operations.
Uses the twin rods to prevent mechanical twist during rapid package diversion on high-speed sorting lines.
To replace the SUD100X175, use the SAUD100X175 direct. It matches the 100mm bore, 175mm stroke, 1/2" port, and FA/LB mounting. If sizing both ways, neighbour bores are 80mm and 100mm; verify your force needs against the equal-both-ways output. A double rod is right when you need anti-rotation or to drive two tools. Because this is a non-magnetic SKU, it cannot take a sensor (the SAUD uses CMSG/DMSG/EMSG sensors). For stroke >=300mm, confirm side-load line limits.
Replacement checklist
Yes, the SUD100X175 is discontinued. The direct replacement is the SAUD100X175, which matches the 100mm bore, 175mm stroke, 1/2" port, and FA/LB mounting.
Force is equal both ways: 3681N @0.5 MPa, 5153N @0.7 MPa, and 6626N @0.9 MPa. The air port is 1/2".
Send us the quantity and destination. We confirm price, stock and lead time on the SAUD100X175 replacement — usually within 7-8 hours.
