This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD63X110, 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 SUD63X110
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X110 is a double-acting profile-type standard cylinder with a Ø63mm bore and 110mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD63X110, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X110
The AirTAC SUD63X110 is a double-acting, double-rod profile cylinder featuring a 63mm bore and 110mm stroke. Because a rod exits both ends on one piston, push and pull force are equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This discontinued extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore and uses a 3/8" port with a 20mm rod. The direct replacement is the SAUD63X110, retaining the same bore, stroke, force, port, and FA/LB mounting.
The double-rod design provides anti-rotation stability and lets the back rod carry a sensor cam or drive two tools simultaneously. Note this SKU lacks a magnet (no -S) and cannot take a magnetic switch. A plain cylinder does not hold loads on air loss; the air cushion only decelerates near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X110 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 SAUD63X110 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 SUD63X110 Is Used
Dual-Tool Transfer
Drives two opposing grippers simultaneously using both rod ends to pick and place parts on a conveyor line.
Anti-Rotation Press
Prevents piston rod twist during a pressing operation, ensuring the tool face remains perfectly aligned.
Symmetric Ejector
Ejects finished components from a machining fixture using equal push and pull force without stroke deflection.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X110 with the SAUD63X110
To replace the discontinued SUD63X110, use the SAUD63X110 direct. The SAU family uses current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. Because force is equal both ways, size both directions by checking neighbour bores. The double-rod layout is right when you need anti-rotation or a back rod to drive two tools. Mounting is Basic, FA, or LB only (matching SC series). For stroke >=300, verify side-load limits. This non-magnetic SKU cannot take switches.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X110
- ✓ 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 SUD63X110 FAQ
Yes, the SUD63X110 is discontinued. The direct replacement is the SAUD63X110, which shares the same 63mm bore, 110mm 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: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. Operating speed is 30-800 mm/s. The cylinder uses a 20mm rod with M16x1.5 thread and a 21mm adjustable air cushion at each end.
