This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X10 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 SUD50X10 is a double-acting profile-type standard cylinder with a Ø50mm bore and 10mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X10, which matches its bore, stroke, force and mounting.
The AirTAC SUD50X10 is a double-acting, double-rod profile cylinder featuring an extruded aluminum barrel. Because a rod exits both ends on a single piston, the push and pull force is equal both ways at 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. This model is discontinued; the exact drop-in replacement is the SAUD50X10, which matches the 50mm bore, 10mm stroke, 1/4" port, and FA/LB mounting. This non-magnetic SKU cannot take a sensor.
The dual-rod design prevents piston rotation and allows driving two tools simultaneously from opposite ends. For sizing, the safe working load is roughly 495 N (60% of the 825 N @0.5 MPa figure), translating to a vertical lift capacity of about 42 kg with a 2:1 margin. Note that air cushions only decelerate near stroke end; an external rod lock is required to hold loads securely without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X10 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 200 kgf | |
The SAUD50X10 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 forming tools simultaneously from a single compact profile body, ensuring perfectly balanced equal-both-ways force for light 10mm pressing tasks.
Transfers small components between two conveyor belts using the twin rods to prevent mechanical rotation without needing external linear guides.
Ejects finished parts from both sides of a machining fixture in a short 10mm stroke, leveraging the shorter profile barrel to save machine footprint.
To replace the discontinued SUD50X10, select the SAUD50X10 drop-in equivalent, which preserves the 50mm bore, 10mm stroke, equal-both-ways force, and 1/4" port. When sizing both ways, verify the 825 N @0.5 MPa output fits your load, or step to neighboring bores (63mm or 40mm) for more or less force. Choose a double-rod cylinder when anti-rotation or driving two tools is required. Mounting is limited to Basic, FA, and LB styles (SC-series compatible only). Since this is a non-magnetic SKU, it cannot accept sensors; upgrading to an SAUD-S allows modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For this 10mm stroke, side-load concerns are minimal, but always guide the load externally on longer strokes.
Replacement checklist
Yes, the SUD50X10 is discontinued. The exact drop-in replacement is the SAUD50X10, which matches the 50mm bore, 10mm stroke, 1/4" port, and FA/LB mounting. The SAUD also offers the SAUF built-in-valve variant the SU line lacked.
The SUD50X10 provides equal force both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. It features a 1/4" port (PT thread), a 20mm rod, and adjustable 21mm cushions at each end.
