This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X200 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X200 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 SUD80X200
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X200 is a double-acting profile-type standard cylinder with a Ø80mm bore and 200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X200, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X200
The AirTAC SUD80X200 is a double-acting, double-rod profile cylinder featuring an extruded aluminium barrel. Because a rod exits both ends on one piston, push and pull force are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This SUD model is discontinued; the exact drop-in replacement is the SAUD80X200, matching the 80mm bore, 200mm stroke, 3/8" port, and FA/LB mounting. This SKU has no magnet and cannot take a sensor.
The dual-rod design prevents rotation and lets the back rod drive a second tool simultaneously. Based on the 2268 N @0.5 MPa output, the safe working load is roughly 1361 N, yielding a vertical lift capacity of about 116 kg with a 2:1 margin. The cylinder operates at 0.15-1.0 MPa with adjustable 28mm cushions. Note that air cushions only decelerate the piston near stroke end; an external rod lock is required to hold loads safely.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X200 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 SAUD80X200 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 SUD80X200 Is Used
Dual-Station Machining
Drives two opposing machining heads simultaneously using both rod ends, maintaining equal force and preventing rotational drift during clamping.
Inline Transfer Pusher
Pushes workpieces from one conveyor lane to another with equal push and pull force, using the through-rod geometry to maintain precise alignment.
Vertical Lift Gate
Actuates a heavy vertical gate where the equal both-ways 2268 N @0.5 MPa force provides consistent lifting and lowering without sagging.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X200 with the SAUD80X200
To replace the discontinued SUD80X200, install the drop-in SAUD80X200, which preserves the 80mm bore, 200mm stroke, 3/8" port, M20x1.5 rod thread, and FA/LB mounting. When sizing both ways, verify your force requirements against the equal both-ways output of 2268 N @0.5 MPa; if you need less force, step down to the 63mm bore, or step up to the 100mm bore for more. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one actuator. This non-magnetic SKU cannot accept sensors, but upgrading to the SAUD allows modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For this 200mm stroke, ensure your mechanical setup accommodates side-load limits. A plain cylinder drifts on air loss, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X200
- ✓ 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 SUD80X200 FAQ
Yes, the SUD80X200 is discontinued. The exact drop-in replacement is the SAUD80X200, which matches the 80mm bore, 200mm stroke, 3/8" port, and FA/LB mounting. The SAUD also supports current CMSG/DMSG/EMSG sensors, whereas this legacy SUD used CS1-B/DS1-B switches.
The SUD80X200 features a 3/8" port and delivers equal force both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. It has a 25mm rod, M20x1.5 rod thread, and 28mm adjustable cushions at each end.
