This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X150S in place of this model. 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 SUD63X150S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X150S 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 drop-in replacement is the SAUD63X150S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X150S
The AirTAC SUD63X150S is a double-acting, double-rod profile cylinder featuring a 63mm bore and 150mm stroke. A piston rod exits both ends of the extruded aluminium barrel, meaning push and pull forces are equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This model is discontinued; the exact drop-in replacement is the SAUD63X150S, which matches the 3/8" port, M16x1.5 rod thread, and 21mm cushions.
The double-rod design prevents piston rotation and allows the rear rod to carry a sensor cam for synchronized tracking. With a 1402 N force at 0.5 MPa, the computed safe working load is roughly 841 N, translating to a vertical lift capacity of about 71 kg with a 2:1 margin. This SUD variant includes a piston magnet for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X150S 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 SAUD63X150S produces the same force from the same bore — a true drop-in on output. 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 SUD63X150S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from a single compact profile body, utilizing the equal both-ways force to ensure balanced cutting or clamping pressure.
Anti-Rotation Transfer Gate
Uses the twin-rod architecture to prevent piston twist during lateral package diversion on a high-speed conveyor line, ensuring smooth mechanical movement.
Synchronized Lift Platform
Employs the back rod to mount a sensor cam for precise position tracking while lifting 71 kg loads vertically with a safe 2:1 working margin.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X150S with the SAUD63X150S
To replace the discontinued SUD63X150S, specify the SAUD63X150S drop-in equivalent, which retains the exact bore, stroke, 3/8" port, and FA/LB mounting. Because force is equal both ways, size it by checking both directions against neighbouring bores (e.g., 50mm or 80mm) to match your load. Choose a double-rod cylinder when you need anti-rotation stability or want to drive two tools simultaneously. If upgrading, note the -S sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. For strokes of 300mm or longer, verify the side-load limits to prevent guide wear. Remember, air cushions only decelerate the piston near end-of-stroke; they do not hold loads on air loss, so add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X150S
- ✓ 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 SUD63X150S FAQ
Yes, the SUD63X150S is discontinued. The exact drop-in replacement is the SAUD63X150S, which matches the 63mm bore, 150mm stroke, 3/8" port, and FA/LB mounting. You simply insert an A after the leading S. The SAUD upgrade also offers the SAUF built-in-valve variant the SU line lacked.
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. The 63mm bore dictates a 3/8" air port, a 20mm piston rod, an M16x1.5 rod thread, and 21mm adjustable air cushions at each end.
