This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X125 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X125 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 SUD32X125
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X125 is a double-acting profile-type standard cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X125, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X125
The AirTAC SUD32X125 is a double-acting, double-rod profile cylinder featuring a 32mm bore and 125mm stroke. A rod exits both ends on a single piston, meaning push and pull force are equal both ways at 345N @0.5 MPa, 483N @0.7 MPa, and 621N @0.9 MPa. This model is discontinued and the exact drop-in replacement is the SAUD32X125, which matches the 1/8" port, M10x1.25 rod thread, and FA/LB mounting. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the rear rod can carry a sensor cam or drive two tools simultaneously while providing anti-rotation stability, this design excels in compact setups. Based on the 345N @0.5 MPa rating, the computed safe working load is ~207N (60% of force), yielding a vertical lift capacity of ~18kg with a 2:1 margin. This non-magnet SKU cannot take a switch, but the SAUD upgrade accepts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Note that air cushions only decelerate near stroke end; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X125 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 SAUD32X125 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. |
| ×125 | 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 SUD32X125 Is Used
Dual-Tool Transfer
Uses both extending rods to push and pull two separate workpieces simultaneously, ensuring perfectly synchronized timing without adding a second cylinder.
Anti-Rotation Guide
The twin rods prevent piston rotation during travel, providing precise linear positioning for delicate pick-and-place handling in tight assembly spaces.
Compact Diverting
Fits into narrow machinery profiles to divert products on a belt, using its equal both ways force to push and retract items smoothly.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X125 with the SAUD32X125
To replace this discontinued SUD32X125, use the SAUD32X125 drop-in (insert an A after the leading S) which keeps the 32mm bore, 125mm stroke, and equal-both-ways force. When sizing both ways, verify your load against the 345N @0.5 MPa figure and consider neighbour bores (40mm yields 528N) if more force is needed. Choose a double rod when anti-rotation or driving two tools is required. Mounting is Basic, FA, or LB only (SC-series compatible). For the -S sensor variant, change from CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 125mm stroke (under 300mm), side-load alignment is standard, but always verify guide tolerances.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X125
- ✓ 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 SUD32X125 FAQ
Yes, the SUD32X125 is discontinued. The exact drop-in replacement is the SAUD32X125, which matches the 32mm bore, 125mm stroke, 1/8" port, and equal-both-ways force. The SAUD also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
Because it is a double-rod cylinder, the push and pull force are equal both ways: 345N @0.5 MPa, 483N @0.7 MPa, and 621N @0.9 MPa. The safe working load is ~207N (60% of the 345N figure), allowing a vertical lift of ~18kg with a 2:1 margin.
