This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD63X300H, 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 SUD63X300H
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X300H 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 SAUD63X300H, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X300H
The AirTAC SUD63X300H is a double-acting, double-rod profile cylinder featuring a 63mm bore, 300mm stroke, and Viton H high-temperature seals rated for 0 to 150 C. 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 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The 3/8 inch port and M16x1.5 rod thread are fixed by the bore. This SUD series is discontinued and the direct replacement is the SAUD63X300H, sharing the same body, bore, stroke, force, and FA/LB mounting.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, double-rod designs offer excellent anti-rotation properties. Note that this specific SKU lacks a magnet and cannot take a magnetic switch. The SAUD successor upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X300H 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 SAUD63X300H 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 SUD63X300H Is Used
High-Temperature Press Ejection
Drives opposing ejector pins in a hot stamping press, utilising the Viton H 150 C seals and equal both ways push/pull force to extract parts reliably.
Dual-Sided Transfer Pusher
Simultaneously indexes two parallel conveyor lanes using both rod ends, ensuring perfectly synchronised material handling without torsional deflection.
Guided Vertical Lift Gate
Actuates a heavy access hatch where the second rod prevents rotation and the 71 kg vertical lift capacity at 0.5 MPa safely balances the gate mass.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X300H with the SAUD63X300H
To replace the discontinued SUD63X300H, specify the SAUD63X300H as a direct retaining the 63mm bore, 300mm stroke, 3/8 port, and equal-both-ways force. When sizing both ways, verify your force requirements against the 1402 N @0.5 MPa output, or step to neighbouring bores (50mm or 80mm) if margins allow. A double rod is right when you need anti-rotation, a back rod to carry a sensor cam, or to drive two tools. Mounting is limited to Basic, FA, and LB (SC-series compatible only). As this SKU has no magnet, the SAUD upgrade shifts sensing from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For the 300mm stroke, use external guides to prevent rod bending and side-load wear. Finally, air cushions only decelerate near stroke end; for load holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X300H
- ✓ 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 SUD63X300H FAQ
Yes, the SUD63X300H is discontinued. The direct replacement is the SAUD63X300H, which matches the 63mm bore, 300mm stroke, 3/8 port, and FA/LB mounting. The SAUD also offers the SAUF built-in-valve variant the SU line lacked.
Force is equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The cylinder does not hold loads on air loss; the 21mm adjustable cushion only decelerates near stroke end. Use an external rod lock for held loads.
