This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X80SH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X80SH 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 SUD80X80SH
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X80SH is a double-acting profile-type standard cylinder with a Ø80mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X80SH, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X80SH
The AirTAC SUD80X80SH is a double-acting, double-rod profile cylinder featuring an extruded aluminium barrel and a 25 mm rod exiting both ends. Because both faces use the rod-side area, push and pull force are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This bore uses a 3/8" port, M20x1.5 rod thread, and 28 mm adjustable air cushions. The SUD80X80SH is discontinued; the exact drop-in replacement is the SAUD80X80SH, matching the 80 mm bore, 80 mm stroke, force, port, and FA/LB mounting. This SH variant includes a piston magnet for legacy CS1-B/DS1-B sensors and Viton H seals for 0 to 150 C high-temperature operation.
The SAUD upgrade uses current CMSG/DMSG/EMSG sensors and offers the SAUF built-in-valve variant. The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam or drive a second tool simultaneously. For sizing, the safe working load is approximately 1361 N (60% of the 0.5 MPa force), yielding a vertical lift capacity of about 116 kg with a 2:1 margin. Note that air cushions only decelerate the piston near stroke end; an external rod lock or pilot-operated check valve is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X80SH 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 SAUD80X80SH 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 SUD80X80SH Is Used
Dual-Tool Press Station
Drives two independent tooling operations from one piston, using both extending rods to push and pull separate assemblies with equal 2268 N force at 0.5 MPa.
Anti-Rotation Transfer Gate
Uses the twin-rod geometry to prevent mechanical twist during rapid part diversion on a 30-800 mm/s packaging line, ensuring smooth lateral transfers.
High-Temp Vertical Lift
Lifts approximately 116 kg of stacked goods in a 0-150 C heat-shrink tunnel, relying on the Viton H seals and equal both-ways force for stable ascent and descent.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X80SH with the SAUD80X80SH
To replace the discontinued SUD80X80SH, order the drop-in SAUD80X80SH, which preserves the 80 mm bore, 80 mm stroke, 3/8" port, and FA/LB mounting compatibility with the AirTAC SC series. Because force is equal both ways, verify your push and pull loads against the 2268 N @0.5 MPa figure, sizing up or down to neighbouring bores if a different capacity is needed. Choose a double-rod cylinder when anti-rotation stability or a back-rod sensor cam is required. If upgrading, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, carefully manage side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X80SH
- ✓ 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 SUD80X80SH FAQ
Yes, the SUD80X80SH is discontinued. The exact drop-in replacement is the SAUD80X80SH, which matches the 80 mm bore, 80 mm stroke, 25 mm rod, 3/8" port, and FA/LB mounting. You must upgrade the piston magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 3/8" ported 80 mm bore provides equal push and pull force of 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This equal both-ways performance is due to the double-rod design having the same effective area on both piston faces.
