This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD63X450S, 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 SUD63X450S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X450S is a double-acting profile-type standard cylinder with a Ø63mm bore and 450mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD63X450S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X450S
The AirTAC SUD63X450S is a discontinued double-acting profile cylinder where a rod exits both ends on one piston, making the push and pull force equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. It features a 63mm bore, 450mm stroke, a 20mm rod, and a 3/8 inch port. The direct replacement is the SAUD63X450S, which matches the bore, stroke, force, and FA/LB mounting while upgrading to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B switches used here.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, this design provides excellent anti-rotation stability. Note that a plain cylinder does not hold loads on air loss; the 21mm adjustable cushions only decelerate near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X450S 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 SAUD63X450S 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.
Where the Airtac SUD Series Double Rod Cylinder SUD63X450S Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously from a single piston, utilising the equal both-ways force to ensure balanced cutting pressure on both sides.
Anti-Rotation Transfer Pusher
Pushes workpieces along a conveyor without rotational drift, using the twin rods to maintain strict alignment during the 450mm transfer stroke.
Symmetric Sorting Diverter
Diverts packages on a high-speed sorting line where the rear rod carries a sensor cam, allowing external position tracking without blocking the primary work area.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X450S with the SAUD63X450S
To replace this discontinued SUD63X450S, order the SAUD63X450S direct (insert an A after the leading S) for identical 63mm bore, 450mm stroke, 3/8 inch port, and equal-both-ways force. When sizing both ways, verify the 1402 N @0.5 MPa output fits your load, or step to neighbouring bores (50mm or 80mm) to scale force. Choose a double-rod cylinder when you need anti-rotation resistance or must drive two tools from one piston. Mounting is limited to Basic, FA, and LB (SC-series compatible only). For the 450mm stroke, add external guides to prevent rod bending under side loads. If using the -S magnet, change legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG on the SAUD.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X450S
- ✓ 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 SUD63X450S FAQ
Yes, the SUD63X450S is discontinued. The direct replacement is the SAUD63X450S, which shares the same 63mm bore, 450mm stroke, 3/8 inch port, and FA/LB mounting. You simply insert an A after the leading S. The main upgrade is that the SAUD uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
Because it is a double-rod cylinder, the force is equal both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. It uses a 3/8 inch port, a 20mm piston rod, and has a 21mm adjustable cushion at each end.
