This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X200S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X200S 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 SUD80X200S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X200S 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 SAUD80X200S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X200S
The AirTAC SUD80X200S is a discontinued double-acting, double-rod profile cylinder with an 80mm bore and 200mm stroke. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. It features a 25mm piston rod, M20x1.5 rod thread, 3/8" port, and 28mm adjustable air cushions at each end. This unit is end-of-life and the exact drop-in replacement is the SAUD80X200S.
Because the second rod prevents piston rotation and can carry a sensor cam or drive a second tool simultaneously, it offers distinct mechanical advantages. The built-in magnet (-S) works with legacy CS1-B/DS1-B switches, while the SAUD replacement upgrades to current CMSG/DMSG/EMSG sensors. For sizing, the 2268N @0.5MPa force yields a safe working load of roughly 1361N and a vertical lift capacity of about 116kg with a 2:1 margin. Note that air cushions only decelerate near stroke end; an external rod lock is required to hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X200S 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 SAUD80X200S 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 SUD80X200S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from one piston, utilizing the equal both-ways force to machine parts on both ends with consistent 3175N @0.7MPa output.
Anti-Rotation Transfer Unit
The twin 25mm rods prevent piston twist during lateral product transfer on a conveyor, ensuring precise alignment without external linear guides.
Symmetric Sorting Diverter
Uses the rear rod to mount a legacy CS1-B/DS1-B sensor cam while the front rod diverts packages, keeping the 3/8" ported profile body compact.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X200S with the SAUD80X200S
To replace the discontinued SUD80X200S, order the drop-in SAUD80X200S, which matches the 80mm bore, 200mm stroke, 3/8" port, and FA/LB mounting. When sizing both ways, verify the equal push/pull force against neighbouring bores (e.g., 63mm or 100mm) to ensure the 2268N @0.5MPa capacity fits your system. A double-rod design is right when you need anti-rotation, a back rod for a sensor cam, or dual-tool driving. The -S suffix indicates a piston magnet; you must change legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors for the SAUD. For this 200mm stroke, side-load alignment is acceptable, but for any stroke >=300mm, ensure guide rails support the load to prevent binding.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X200S
- ✓ 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 SUD80X200S FAQ
Yes, the SUD80X200S is discontinued. The exact drop-in replacement is the SAUD80X200S, which shares the same 80mm bore, 200mm stroke, equal both-ways force, 3/8" port, and FA/LB mounting. You only need to upgrade the switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
Being a double-rod cylinder, the force is equal both ways: 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. It operates at speeds of 30-800mm/s, uses a 3/8" port, and features 28mm adjustable air cushions at each end. It does not hold loads on air loss without an external rod lock.
