This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X150S 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 SUD32X150S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X150S is a double-acting profile-type standard cylinder with a Ø32mm bore and 150mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X150S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X150S
The AirTAC SUD32X150S is a discontinued double-acting double-rod profile cylinder with a 32mm bore and 150mm stroke. A rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal at 345N @0.5MPa, 483N @0.7MPa, and 621N @0.9MPa. The exact drop-in replacement is the SAUD32X150S, which matches the 1/8 port, M10x1.25 rod thread, and 21mm cushion. This extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the rear rod can carry a sensor cam while the front rod drives a tool, the double-rod design prevents rotation and enables compact dual-work operations. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches; the SAUD replacement upgrades to current CMSG/DMSG/EMSG sensors. Based on the 345N @0.5MPa figure, the safe working load is roughly 207N (60%), translating to a vertical lift capacity of about 18kg with a 2:1 margin. Note that air cushions only decelerate near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X150S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUD32X150S 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.

| 32 | Bore size in mm. |
| ×150 | 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 SUD32X150S Is Used
Dual-Tool Transfer
Simultaneously drives and synchronises two separate pick-and-place tools from a single compact profile body.
Anti-Rotation Guiding
The twin rods exiting both ends prevent piston rotation without external guides, ensuring precise linear tracking.
Compact Cam Positioning
Uses the rear rod to carry a sensor cam while the front rod handles the primary work in tight machinery layouts.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X150S with the SAUD32X150S
To replace the discontinued SUD32X150S, order the drop-in SAUD32X150S, which preserves the 32mm bore, 150mm stroke, equal both-ways force, and FA/LB mounting compatibility with the AirTAC SC series. Size both directions by comparing neighbouring bores, as the equal push and pull force dictates the true capacity. Choose a double-rod cylinder when anti-rotation or driving two tools is required. If using the -S magnet, swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors. For this 150mm stroke (under 300mm), side-load alignment is straightforward, but always verify guiding for longer strokes.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X150S
- ✓ 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 SUD32X150S FAQ
Yes, the SUD32X150S is discontinued. The exact drop-in replacement is the SAUD32X150S, which matches the 32mm bore, 150mm stroke, 1/8 port, and equal both-ways force. You only need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, force is equal both ways: 345N @0.5MPa, 483N @0.7MPa, and 621N @0.9MPa. The fixed port size for the 32mm bore is 1/8 inch. The safe working load is approximately 207N at 0.5MPa.
