This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X125 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X125 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 SUD80X125
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X125 is a double-acting profile-type standard cylinder with a Ø80mm bore and 125mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X125, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X125
The AirTAC SUD80X125 is a discontinued double-acting profile cylinder featuring a rod exiting both ends. This design yields equal force in both directions, rated at 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The exact drop-in replacement is the SAUD80X125, matching the 80mm bore, 125mm stroke, 3/8 inch port, and mounting. This SKU lacks a magnet and cannot accept sensors.
Because the second rod acts as an anti-rotation guide and can drive a second tool simultaneously, it is highly effective for compact multi-action stations. Based on the 2268 N output at 0.5 MPa, the computed safe working load is approximately 1361 N, translating to a vertical lift capacity of roughly 116 kg with a 2:1 margin. Note that a plain cylinder drifts on air loss; the 28 mm adjustable cushions only decelerate near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X125 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUD80X125 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 SUD80X125 Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously with equal 2268 N force at 0.5 MPa, ensuring balanced cutting or forming without requiring a second cylinder.
Anti-Rotation Transfer Gate
Uses the twin rod structure to prevent mechanical twist during rapid 30-800 mm/s part diversion on high-speed packaging lines.
Compact Vertical Lifter
Lifts loads up to 116 kg with a 2:1 safety margin, fitting into tight machine frames due to the extruded aluminium profile barrel being shorter than standard alternatives.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X125 with the SAUD80X125
To replace the discontinued SUD80X125, order the SAUD80X125 drop-in, which retains the 3/8 inch port, M20x1.5 rod thread, and FA/LB mounting. Size both directions by checking the 2268 N force at 0.5 MPa against your load, stepping to neighbouring bores if margins require. A double rod is right when you need anti-rotation or dual-tool driving. Since this SKU is non-magnetic, it cannot take sensors; if upgrading to an -S SAUD, switch from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. For strokes >=300, verify side-load line limits.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X125
- ✓ 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 SUD80X125 FAQ
Yes, the SUD80X125 is discontinued. The exact drop-in replacement is the SAUD80X125, which matches the 80mm bore, 125mm stroke, 3/8 inch port, and FA/LB mounting.
The 3/8 inch ported double-rod design provides equal force both ways: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 28 mm cushions only decelerate the load; they do not hold it without live air.
