This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X650S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X650S 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 SUD100X650S is a double-acting profile-type standard cylinder with a Ø100mm bore and 650mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X650S, which matches its bore, stroke, force and mounting.
The AirTAC SUD100X650S is a double-acting, double-rod profile cylinder featuring a 100mm bore and 650mm stroke. A rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal at 3681N @0.5 MPa, 5153N @0.7 MPa, and 6626N @0.9 MPa. This model is discontinued and the exact drop-in replacement is the SAUD100X650S, which retains the same bore, stroke, force, 1/2 inch port, and FA/LB mounting. The SAUD upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy SUD used CS1-B/DS1-B switches.
The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. With a 650mm stroke, external guides are recommended to prevent rod bending and manage side loads. Based on the 3681N @0.5 MPa force, the safe working load is about 2209N (60 percent of force), yielding a vertical lift capacity of approximately 188kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the 29mm adjustable air cushions only decelerate near stroke end, so an external rod lock is required for held loads.

The SAUD100X650S 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.
Drives two opposing tools simultaneously with equal both ways force, utilizing the 100mm bore for 3681N @0.5 MPa cutting or clamping pressure.
The double-rod design prevents piston rotation during a 650mm transfer stroke, ensuring precise material handling without torsional deflection.
Uses the rear extending rod to carry a sensor cam, operating legacy CS1-B/DS1-B switches to confirm gate position on a packaging line.
To replace the discontinued SUD100X650S, use the drop-in SAUD100X650S, keeping the 100mm bore, 650mm stroke, 1/2 inch port, and FA/LB mounting unchanged. When sizing both ways, verify the equal both ways force fits your needs: the neighbouring 80mm bore yields 2268N @0.5 MPa, while this 100mm bore provides 3681N @0.5 MPa. A double rod is right when you need anti-rotation stability, want the back rod to carry a sensor cam, or need to drive two tools simultaneously. Because this unit has the -S magnet, upgrade your legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For the 650mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
Yes, the SUD100X650S is discontinued. The exact drop-in replacement is the SAUD100X650S, which matches the 100mm bore, 650mm stroke, 1/2 inch port, and FA/LB mounting. You must upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
Force is equal both ways at 3681N @0.5 MPa, 5153N @0.7 MPa, and 6626N @0.9 MPa. The speed range is 30-800 mm/s. The 1/2 inch port and 29mm adjustable cushions handle deceleration, but an external rod lock is required for load holding.
