This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD63X300, 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 SUD63X300
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X300 is a double-acting profile-type standard cylinder with a Ø63mm bore and 300mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD63X300, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X300
The AirTAC SUD63X300 is a double-acting, double-rod profile cylinder featuring a 63mm 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 1402N @0.5MPa, 1962N @0.7MPa, and 2523N @0.9MPa. This discontinued model uses an extruded aluminum profile barrel, a 20mm rod, M16x1.5 rod threads, and a 3/8" port. As a direct replacement, the SAUD63X300 matches the exact bore, stroke, force, port, and FA/LB mounting.
This non-magnetic SKU (no -S suffix) cannot take a sensor, whereas the SAUD upgrade supports current CMSG/DMSG/EMSG sensors (this legacy unit used CS1-B/DS1-B). The dual-rod design drives two tools simultaneously and provides anti-rotation stability. Note that air cushions only decelerate the piston near stroke end; a plain cylinder drifts on air loss, so use an external rod lock for load holding. At 300mm stroke, external guides are recommended to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X300 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUD63X300 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 SUD Series Double Rod Cylinder SUD63X300 Is Used
Dual-Tool Drive
Drives two opposing tools simultaneously from one body, utilizing the equal push and pull force on both rod ends for synchronized gripping.
Transfer Pusher
Pushes parts across a conveyor using the 3/8" port cylinder, relying on adjustable cushions to decelerate the 300mm stroke smoothly.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X300 with the SAUD63X300
To replace the discontinued SUD63X300, use the SAUD63X300 direct: it preserves the 63mm bore, 300mm stroke, 3/8" port, and FA/LB mounting. When sizing both ways, neighboring bores (50mm or 80mm) alter the equal-both-ways force, so stick with 63mm if 1402N @0.5MPa is required. A double rod is right when you need anti-rotation stability or must drive two tools from one cylinder. This non-magnetic SKU cannot take a switch; the SAUD upgrade uses CMSG/DMSG/EMSG sensors (legacy was CS1-B/DS1-B). For this 300mm stroke, add external guides to manage side-load and rod-bending risks.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X300
- ✓ 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 SUD63X300 FAQ
Yes, the SUD63X300 is discontinued. The direct replacement is the SAUD63X300, which matches the 63mm bore, 300mm stroke, 3/8" port, and FA/LB mounting.
Force is equal both ways at 1402N @0.5MPa, 1962N @0.7MPa, and 2523N @0.9MPa. The port is 3/8". Air cushions only decelerate; use an external rod lock for load holding.
