This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD100X300, 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 SUD Series Double Rod Cylinder SUD100X300
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X300 is a double-acting profile-type standard cylinder with a Ø100mm bore and 300mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD100X300, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X300
The AirTAC SUD100X300 is a double-acting, double-rod profile cylinder featuring a 100mm bore and 300mm stroke. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 3681N @0.5 MPa, 5153N @0.7 MPa, and 6626N @0.9 MPa. This legacy model is discontinued; the direct replacement is the SAUD100X300, retaining the 1/2 inch port, M20x1.5 rod thread, and 29mm adjustable cushions.
Because the second rod drives a tool or sensor cam from the back, it offers anti-rotation stability without needing a separate guide. This non-magnetic SKU cannot take a switch. Note that air cushions only decelerate near stroke end; a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X300 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 SAUD100X300 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 100 | Bore size in mm. |
| ×300 | 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.
Where the Airtac SUD Series Double Rod Cylinder SUD100X300 Is Used
Dual-Tool Machining Station
Simultaneously drives opposing tools from both rod ends, utilizing the equal both-ways force to machine parts efficiently on a single axis.
Anti-Rotation Transfer Gate
Uses the double-rod geometry to prevent mechanical rotation during high-speed package transfers, ensuring precise alignment without external guides.
Symmetric Clamping Fixture
Applies 3681N of equal clamping force from opposite sides at 0.5 MPa, securely holding heavy workpieces for industrial assembly.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X300 with the SAUD100X300
To replace the discontinued SUD100X300, use the SAUD100X300 direct: same profile body, 100mm bore, 300mm stroke, equal-both-ways force, 1/2 port, and FA/LB mounting. If you need to size both ways, check the 80mm and 100mm bores to match your exact force requirements. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools simultaneously. This non-magnetic SKU cannot take a sensor; if upgrading to SAUD with an -S suffix, switch from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. For this 300mm stroke, add external guides to prevent rod-bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X300
- ✓ 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 SUD Series Double Rod Cylinder SUD100X300 FAQ
Yes, the SUD100X300 is discontinued. The direct replacement is the SAUD100X300, which matches the 100mm bore, 300mm stroke, equal-both-ways force, 1/2 port, and FA/LB mounting.
The 1/2 inch port feeds equal both-ways force of 3681N @0.5 MPa, 5153N @0.7 MPa, and 6626N @0.9 MPa.
