This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X100 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 SUD80X100
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X100 is a double-acting profile-type standard cylinder with a Ø80mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X100, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X100
The AirTAC SUD80X100 is a double-acting profile cylinder featuring a 25 mm rod exiting both ends, yielding equal push and pull force of 2268 N at 0.5 MPa. This 80 mm bore unit uses a 3/8 inch port and 28 mm adjustable cushions. As a discontinued model, its exact drop-in replacement is the SAUD80X100, retaining the same compact profile body, stroke, and FA/LB mounting.
Because the rear rod can drive a second tool or carry a sensor cam, double-rod designs excel at anti-rotation. Based on the 2268 N output, the safe working load is roughly 1361 N, translating to a 116 kg vertical lift with a 2:1 margin. Note this non-magnetic SKU cannot accept switches. The SAUD upgrade switches to CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X100 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 SAUD80X100 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 SUD80X100 Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously from one piston, utilising the equal both-ways force to maintain balanced cutting pressure.
Anti-Rotation Transfer Gate
Uses the twin rods to prevent mechanical twist during rapid package diversion on a high-speed sorting line.
Compact Vertical Lifter
Lifts a 116 kg payload with a 2:1 safety margin using the 0.5 MPa equal force, saving space with its short profile barrel.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X100 with the SAUD80X100
To replace the discontinued SUD80X100, install the drop-in SAUD80X100, which matches the 80 mm bore, 100 mm stroke, 3175 N equal-both-ways force at 0.7 MPa, and FA/LB mounts. If sizing both ways, check the 63 mm and 100 mm neighbour bores to meet your equal force requirements. A double rod is right when you need anti-rotation or must drive two tools. This non-magnetic SKU cannot take sensors, but the SAUD accepts current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear. A plain cylinder drifts on air loss; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X100
- ✓ 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 SUD80X100 FAQ
Yes, the SUD80X100 is discontinued. The exact drop-in replacement is the SAUD80X100, which matches the 80 mm bore, 100 mm stroke, 3/8 inch port, and FA/LB mounting.
The 3/8 inch ported SUD80X100 provides equal push and pull force of 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The air cushion only decelerates the load near stroke end and does not hold it without live air.
