This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD63X150, 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 SUD63X150
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X150 is a double-acting profile-type standard cylinder with a Ø63mm bore and 150mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD63X150, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X150
The AirTAC SUD63X150 is a discontinued double-acting profile cylinder featuring a rod exiting both ends, yielding equal push and pull force of 1402 N at 0.5 MPa. It uses a 63mm bore, 150mm stroke, and a 3/8 inch port. The direct replacement is the SAUD63X150, retaining the exact bore, stroke, and mounting. Because two rods secure the piston, the design resists rotation and lets the back rod drive a second tool or sensor cam.
Buyers should note this non-magnetic SKU cannot accept switches, whereas the SAUD upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. A plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X150 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 SAUD63X150 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 SUD63X150 Is Used
Dual-Tool Machining
Drive two opposing machining heads simultaneously with equal force in both directions, utilizing the twin rods for perfectly synchronized tool actuation.
Anti-Rotation Transfer
Prevent piston rotation during lateral part pushing on a conveyor line, ensuring the end effector remains perfectly aligned without external guides.
Symmetric Clamping
Clamp workpieces from both sides equally using the extended rear rod, maintaining balanced pressure and centering the component during packaging.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X150 with the SAUD63X150
To replace this discontinued SUD63X150, order the SAUD63X150 direct, which matches the 63mm bore, 150mm stroke, 3/8 inch port, and FA/LB mounting. Size both directions by checking neighbour bores, as the double-rod construction ensures force is equal both ways (1402 N at 0.5 MPa). Choose a double-rod model when you need anti-rotation or must drive two tools. Since this specific SKU lacks a magnet, it cannot take sensors, but upgrading to the SAUD lets you use CMSG/DMSG/EMSG switches. For this 150mm stroke, ensure your side-load alignment is correct to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X150
- ✓ 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 SUD63X150 FAQ
Yes, the SUD63X150 is discontinued. The direct replacement is the SAUD63X150, which shares the same 63mm bore, 150mm stroke, 3/8 inch port, and FA/LB mounting. The SAUD also supports current CMSG/DMSG/EMSG sensors.
Because it is a double-rod cylinder, the force is equal both ways: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
