This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X620S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X620S 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 SUD100X620S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X620S is a double-acting profile-type standard cylinder with a Ø100mm bore and 620mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X620S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X620S
The AirTAC SUD100X620S is a discontinued double-acting double-rod profile cylinder where a rod exits both ends, ensuring push and pull force is equal both ways (3681 N at 0.5 MPa, 5153 N at 0.7 MPa, 6626 N at 0.9 MPa). The exact drop-in replacement is the SAUD100X620S, matching the 100mm bore, 620mm stroke, 1/2" port, M20x1.5 rod thread, and FA/LB mounting. The extruded aluminum profile barrel is notably shorter than an ISO 15552 cylinder of the same bore.
With a 620mm stroke, external guides are recommended to manage side-load and rod-bending risks. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAUD requires current CMSG/DMSG/EMSG sensors. For sizing, the safe working load is roughly 2209 N (60% of the 0.5 MPa force), allowing a vertical lift of about 188 kg with a 2:1 margin. Note that air cushions (29mm adjustable at each end) only decelerate the load; an external rod lock or pilot-operated check valve is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X620S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X620S 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 SUD100X620S Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously from one piston, utilizing the equal both ways force to maintain perfectly synchronized cutting cycles.
Anti-Rotation Transfer Unit
Uses the twin rods exiting both ends to prevent mechanical rotation during heavy workpiece transfers, ensuring precise alignment on a 100mm bore profile body.
Vertical Lift Fixture
Lifts payloads up to 188 kg with a 2:1 safety margin at 0.5 MPa, relying on external guides to handle side-load across the 620mm stroke.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X620S with the SAUD100X620S
To replace the discontinued SUD100X620S, use the drop-in SAUD100X620S, which preserves the bore, stroke, equal-both-ways force, 1/2" port, and FA/LB mounting. When sizing both ways, verify the 3681 N force at 0.5 MPa is sufficient, or evaluate neighboring bores. A double rod is ideal when you need anti-rotation stability or want to drive two tools simultaneously from one piston. Because this unit has a 620mm stroke, you must account for side-load and rod-bending by using external guides. The -S suffix means a sensor change is required: migrate from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG equivalents used by the SAUD family. Remember that cushions only decelerate; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X620S
- ✓ 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 SUD100X620S FAQ
Yes, the SUD100X620S is discontinued. The exact drop-in replacement is the SAUD100X620S, which matches the 100mm bore, 620mm stroke, 1/2" port, and FA/LB mounting. You will need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG models.
Because it is a double-rod cylinder, force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It operates at speeds of 30-800 mm/s, features a 1/2" port, and has 29mm adjustable air cushions at each end.
