This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD63X160, 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 SUD63X160
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X160 is a double-acting profile-type standard cylinder with a Ø63mm bore and 160mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD63X160, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X160
The AirTAC SUD63X160 is a discontinued double-acting double-rod profile cylinder. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The direct replacement is the SAUD63X160, which matches the 63mm bore, 160mm stroke, 3/8" port, and FA/LB mounting. This non-magnetic SKU cannot take a sensor.
The double-rod design prevents rotation and lets the back rod drive a second tool. The SAUD upgrade switches to current CMSG/DMSG/EMSG sensors. A plain cylinder drifts on air loss; the cushion only decelerates, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X160 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 SAUD63X160 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUD Series Double Rod Cylinder SUD63X160
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×160 | 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 SUD63X160 Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously using both extending and retracting rod ends, maintaining equal 1962 N force at 0.7 MPa.
Anti-Rotation Transfer Gate
The twin-rod architecture prevents mechanical twist during lateral package diversion on a 3/8" port powered profile cylinder assembly.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X160 with the SAUD63X160
To replace the discontinued SUD63X160, order the direct replacement SAUD63X160, which keeps the 63mm bore, 160mm stroke, M16x1.5 rod thread, 3/8" port, and FA/LB mounting. Size both directions by checking equal force across neighbor bores. Choose a double-rod when you need anti-rotation or to drive two tools. This non-magnetic SKU takes no sensor; the SAUD uses CMSG/DMSG/EMSG sensors. For this 160mm stroke, verify side-load alignment. The cushion only decelerates; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X160
- ✓ 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 SUD63X160 FAQ
Yes, the SUD63X160 is discontinued. The direct replacement is the SAUD63X160, which matches the 63mm bore, 160mm stroke, 3/8" port, and FA/LB mounting. The SAUD also adds compatibility with current CMSG/DMSG/EMSG sensors.
Because it is a double-rod cylinder, 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. This non-magnetic SKU cannot take a sensor.
