This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X160 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X160 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 SUD50X160 is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X160, which matches its bore, stroke, force and mounting.
The AirTAC SUD50X160 is a double-acting, double-rod profile cylinder featuring a 50mm bore and 160mm 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 825N @0.5 MPa, 1154N @0.7 MPa, and 1484N @0.9 MPa. This SUD model is discontinued and end-of-life; the exact drop-in replacement is the SAUD50X160 (SAUD family), matching the 1/4" port, M16x1.5 rod thread, and 21mm cushions. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the second rod drives a second tool or acts as an anti-rotation guide, this design suits multi-tool stations. At 0.5 MPa, the computed safe working load is ~495N (about 60% of the 825N figure), allowing a vertical lift of ~42kg with a 2:1 margin. This SKU has no magnet (-S), so it cannot take a magnetic switch. The SAUD upgrade switches to current CMSG/DMSG/EMSG sensors (this legacy model used CS1-B/DS1-B). A plain cylinder does not hold loads on air loss; the cushion only decelerates, so use an external rod lock for held loads.

The SAUD50X160 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 one piston, utilising the equal both-ways force to machine parts on both the extend and retract strokes.
The twin rods exiting both ends prevent mechanical rotation during travel, ensuring highly precise linear transfer without needing external guides.
Sorts products on a line by pushing and pulling with identical 825N force at 0.5 MPa, ensuring consistent actuation speed regardless of travel direction.
To replace the discontinued SUD50X160, order the drop-in SAUD50X160, which shares the exact 50mm bore, 160mm stroke, equal-both-ways force, 1/4" port, and FA/LB mounting. Size both ways by checking neighbouring bores (40mm or 63mm) against your force requirements, remembering the double-rod design provides equal push and pull. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools simultaneously. Mounting is compatible with the AirTAC SC series only. This non-magnetic SKU cannot take sensors, but if upgrading to a -S SAUD, note the sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 160mm stroke (under 300mm), side-load alignment is less critical than on longer strokes, but always guide the rod end.
Replacement checklist
Yes, the SUD50X160 is discontinued. The exact drop-in replacement is the SAUD50X160. It matches the 50mm bore, 160mm stroke, 1/4" port, and FA/LB mounting, while upgrading to current CMSG/DMSG/EMSG sensors.
The double-rod design provides equal force both ways: 825N @0.5 MPa, 1154N @0.7 MPa, and 1484N @0.9 MPa. Operating speed is 30-800 mm/s. The 1/4" port and 21mm adjustable cushions manage end-of-stroke deceleration.
