This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X200 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X200 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 SUD50X200 is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X200, which matches its bore, stroke, force and mounting.
The AirTAC SUD50X200 is a double-acting, double-rod profile cylinder featuring a 50mm bore and 200mm stroke. A piston rod exits both ends, meaning push and pull forces are equal at 825N @0.5 MPa, 1154N @0.7 MPa, and 1484N @0.9 MPa. This model is discontinued; the exact drop-in replacement is the SAUD50X200, retaining the identical 1/4" port, M16x1.5 rod thread, and FA/LB mounting. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the rod exits both ends, the back rod can drive a second tool or carry a sensor cam while providing anti-rotation stability. Based on the 825N force at 0.5 MPa, the computed safe working load is roughly 495N, and it can vertically lift approximately 42kg with a 2:1 margin. Note this SKU lacks a magnet (-S) and cannot take a sensor; furthermore, a plain cylinder does not hold loads on air loss—the cushion only decelerates near stroke end, so an external rod lock is required for holding.

| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUD50X200 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 from a single piston, utilizing the equal push and pull force to machine both sides of a workpiece evenly.
Transfers parts across a conveyor using both rod ends, where the anti-rotation properties of the double-rod design maintain precise alignment during lateral movement.
Lifts guided pallets vertically, taking advantage of the equal both ways force to securely raise and lower loads up to the 42kg vertical lift threshold.
To replace the discontinued SUD50X200, order the SAUD50X200 drop-in: same 50mm bore, 200mm stroke, equal-both-ways force, 1/4" port, and FA/LB mounting. When sizing both ways, verify the 825N @0.5 MPa output meets your needs, or step to neighboring bores (63mm or 40mm) for more or less force. A double rod is right when you need equal push/pull force or anti-rotation. If upgrading sensing, note the SAUD uses CMSG/DMSG/EMSG sensors (this legacy model used CS1-B/DS1-B). For stroke lengths >=300mm, ensure side-load alignment to prevent rod binding.
Replacement checklist
Yes, the SUD50X200 is discontinued. The exact drop-in replacement is the SAUD50X200, which matches the 50mm bore, 200mm stroke, 1/4" port, and FA/LB mounting.
Force is equal both ways: 825N @0.5 MPa, 1154N @0.7 MPa, and 1484N @0.9 MPa. The air port is 1/4". The cushion only decelerates; it does not hold loads on air loss.
