This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X100S 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 SUD80X100S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X100S 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 SAUD80X100S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X100S
The AirTAC SUD80X100S is a double-acting, double-rod profile cylinder featuring an extruded aluminium barrel that is shorter than an ISO 15552 unit of the same bore. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push and pull force are equal. This discontinued model is directly replaced by the SAUD80X100S, which retains the 80mm bore, 100mm stroke, 3/8" port, and FA/LB mounting interface.
With a 25mm piston rod, M20x1.5 rod-end thread, and 28mm adjustable air cushions at each end, it delivers equal force of 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa. The double-rod design prevents rotation and allows the back rod to carry a sensor cam. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches; the SAUD replacement uses current CMSG/DMSG/EMSG sensors. For sizing, the safe working load is roughly 1361N (60% of the 0.5MPa force), yielding a vertical lift capacity of about 116kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the cushion only decelerates, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X100S 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 SAUD80X100S 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 SUD80X100S Is Used
Twin-Tool Workholding
Drives two opposing tools simultaneously from a single piston, utilising the equal both-ways force to machine both faces of a part without requiring a second cylinder.
Anti-Rotation Transfer
Transfers parts across a conveyor belt using the double-rod geometry to resist torsional twisting and maintain precise alignment during the push and pull strokes.
Cam-Actuated Gauging
Uses the rear extending rod to carry a sensor cam, triggering external position switches to verify stroke completion and part dimensions before the main tool advances.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X100S with the SAUD80X100S
To replace the discontinued SUD80X100S, order the drop-in SAUD80X100S, which matches the 80mm bore, 100mm stroke, 3/8" port, and FA/LB mounting. When sizing both ways, verify the equal push/pull force fits your needs; if 2268N at 0.5MPa is excessive, step down to the 63mm bore (1402N), or if insufficient, step up to the 100mm bore (3681N). A double rod is right when you need anti-rotation, equal both-ways force, or a back rod to drive a second tool. Because this unit has a -S magnet, you must change from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the SAUD. For this 100mm stroke, side-load is minimal, but for strokes >=300mm ensure guide alignment to prevent binding. Mounting is compatible with the AirTAC SC series only.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X100S
- ✓ 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 SUD80X100S FAQ
Yes, the SUD80X100S is discontinued. The exact drop-in replacement is the SAUD80X100S. It offers the same 80mm bore, 100mm stroke, 3/8" port, and FA/LB mounting. You will need to upgrade the position switches from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG sensors used by the SAUD.
The double-rod design provides equal force both ways: 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa. It operates at speeds between 30 and 800 mm/s. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa and a temperature range of -20 to +70 C.
