This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X50 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.

The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X50 is a double-acting profile-type standard cylinder with a Ø100mm bore and 50mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X50, which matches its bore, stroke, force and mounting.
The AirTAC SUD100X50 is a double-acting, double-rod profile cylinder featuring a 100mm bore and 50mm stroke. Because a rod exits both ends on one piston, push and pull force are equal both ways, rated at 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. This model is discontinued and the exact drop-in replacement is the SAUD100X50, retaining the same 1/2 inch port, M20x1.5 rod thread, and 29mm adjustable cushions.
Using a double-rod design provides anti-rotation stability and allows the back rod to drive a second tool simultaneously. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. For sizing, the safe working load is roughly 2209 N (about 60 percent of the 0.5 MPa force), yielding a vertical lift capacity of 188 kg with a 2:1 margin. This non-magnetic SKU cannot take a switch. A plain cylinder does not hold loads on air loss; the cushion only decelerates, so use an external rod lock for held loads.

| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X50 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.
Use the back rod to drive a secondary tool simultaneously, leveraging the equal both ways force for balanced 3681 N operations at 0.5 MPa.
The double-rod profile prevents piston rotation during part transfer on conveyor lines, ensuring precise alignment without lateral play.
Lift loads up to 188 kg with a 2:1 safety margin, using the compact profile barrel to save space in tight material handling cells.
To replace the discontinued SUD100X50, select the SAUD100X50 drop-in, which matches the 100mm bore, 50mm stroke, 1/2 inch port, and FA/LB mounting. Size both ways by checking neighbor bores to ensure the equal both ways force (3681 N at 0.5 MPa) meets your needs. A double rod is right when you need anti-rotation stability or dual-tool driving. Since this SKU lacks a magnet, sensing requires upgrading to CMSG/DMSG/EMSG sensors on the SAUD. For strokes >=300, verify side-load line limits. Remember, air cushions only decelerate; use an external rod lock for load holding.
Replacement checklist
Yes, the SUD100X50 is discontinued. The exact drop-in replacement is the SAUD100X50, which matches the 100mm bore, 50mm stroke, 1/2 inch port, and FA/LB mounting. You must upgrade sensors to CMSG/DMSG/EMSG, as this legacy model used CS1-B/DS1-B.
The SUD100X50 features a 1/2 inch port and delivers equal force both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It uses an M20x1.5 rod thread and has a 29mm adjustable cushion at each end.
