This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X25 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X25 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 SUD80X25
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X25 is a double-acting profile-type standard cylinder with a Ø80mm bore and 25mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X25, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X25
The AirTAC SUD80X25 is a double-acting, double-rod profile cylinder featuring a 80mm bore and 25mm stroke. A rod exits both ends on a single piston, meaning push and pull force are equal at 2268N @0.5MPa, 3175N @0.7MPa and 4082N @0.9MPa. The extruded aluminium barrel is more compact than standard alternatives, and the 3/8" port with M20x1.5 rod thread provides robust pneumatic performance. This SUD80X25 model is discontinued and the exact drop-in replacement is the SAUD80X25.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, the dual-rod design offers excellent anti-rotation stability. At 0.5MPa the safe working load is roughly 1361N (60% of rated force), yielding a vertical lift capacity of about 116kg with a 2:1 margin. Note this SKU lacks a magnet (-S) and cannot accept switches; the SAUD upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. A plain cylinder drifts on air loss—the 28mm 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 SAUD80X25 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 SAUD80X25 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 SUD80X25 Is Used
Dual-Tool Synchronisation
Drives two independent work operations simultaneously from one piston, utilising both extending rods to maintain perfectly equal timing and 2268N force at 0.5MPa.
Anti-Rotation Lifting
Lifts vertical loads up to approximately 116kg with a 2:1 safety margin without twisting, as the twin 25mm rods prevent rotational drift inherent to single-rod actuators.
Compact Transfer Pusher
Pushes parts across a conveyor using the shorter extruded aluminium profile barrel, saving machine footprint while delivering 3175N equal push and pull force at 0.7MPa.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X25 with the SAUD80X25
To replace the discontinued SUD80X25, specify the SAUD80X25 drop-in: it matches the 80mm bore, 25mm stroke, 3175N equal-both-ways force @0.7MPa, 3/8" port and FA/LB mounting. When sizing both ways, verify the 2268N @0.5MPa output fits your load, or step to neighbouring bores for more force. Choose a double-rod when you need anti-rotation or to drive two tools. This non-magnetic SKU cannot take sensors; if switching, the SAUD uses CMSG/DMSG/EMSG sensors. For this 25mm stroke side-load is minimal, but for strokes >=300mm ensure guide alignment to prevent binding.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X25
- ✓ 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 SUD80X25 FAQ
Yes, the SUD80X25 is discontinued. The exact drop-in replacement is the SAUD80X25, which shares the same 80mm bore, 25mm stroke, 3/8" port, FA/LB mounting and equal both-ways force. The SAUD also offers the SAUF built-in-valve variant and uses current CMSG/DMSG/EMSG sensors.
The SUD80X25 provides equal force both ways: 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. It operates at speeds of 30-800mm/s. The 28mm adjustable air cushions decelerate the load near stroke end, but an external rod lock is required for load holding on air loss.
