This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X100 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 SUD50X100
The AirTAC Airtac SUD Series Double Rod Cylinder SUD50X100 is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X100, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD50X100
The AirTAC SUD50X100 is a double-acting, double-rod profile cylinder featuring a 50mm bore and 100mm stroke. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 825N @0.5MPa, 1154N @0.7MPa, and 1484N @0.9MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. This SUD50X100 model is discontinued; the exact drop-in replacement is the SAUD50X100, matching the 1/4" port, M16x1.5 rod thread, and FA/LB mounting.
The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam or drive two tools simultaneously. This SKU lacks a magnet and cannot take a magnetic switch. For buyers sizing the 825N @0.5MPa output, the safe working load is approximately 495N (60%), yielding a vertical lift capacity of about 42kg with a 2:1 margin. A plain cylinder does not hold loads on air loss; the air cushion only decelerates near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUD50X100 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 SUD50X100 Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously with equal 825N force at 0.5MPa, keeping cycle times balanced via both extending rods.
Anti-Rotation Transfer Gate
Uses the double-rod geometry to prevent mechanical twist during part diversion on a conveyor line, ensuring smooth profile barrel operation.
Symmetric Clamping Fixture
Clamps workpieces from both ends equally, using the matched push and pull forces to center components securely without single-rod imbalance.
Replacing the Airtac SUD Series Double Rod Cylinder SUD50X100 with the SAUD50X100
To replace the discontinued SUD50X100, order the SAUD50X100 drop-in: it preserves the 50mm bore, 100mm stroke, equal-both-ways force, 1/4" port, and FA/LB mounting. When sizing both ways, verify the 825N @0.5MPa force fits your application, or step to neighbouring bores (63mm for more power, 40mm for less). Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one piston. This non-magnetic SKU cannot accept sensors, whereas the SAUD upgrade uses current CMSG/DMSG/EMSG sensors (the SUD used legacy CS1-B/DS1-B). For this 100mm stroke, side-load is minimal, but for any stroke >=300mm ensure guide alignment to prevent rod binding. Mounting is compatible with the AirTAC SC series only.
Replacement checklist
- ✓ Same bore / stroke → SAUD50X100
- ✓ 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 SUD50X100 FAQ
Yes, the SUD50X100 is discontinued. The exact drop-in replacement is the SAUD50X100, which matches the 50mm bore, 100mm stroke, equal-both-ways force, 1/4" port, and FA/LB mounting.
The double-rod design yields equal force both ways: 825N @0.5MPa, 1154N @0.7MPa, and 1484N @0.9MPa. The 50mm bore features a 1/4" air port, a 20mm rod, and a 21mm adjustable cushion at each end.
