This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X170S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X170S 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 SUD63X170S is a double-acting profile-type standard cylinder with a Ø63mm bore and 170mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X170S, which matches its bore, stroke, force and mounting.
The AirTAC SUD63X170S is a double-acting, double-rod profile cylinder featuring a 63mm bore and 170mm stroke. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This model is discontinued; the exact drop-in replacement is the SAUD63X170S, sharing the same 3/8" port, M16x1.5 rod thread, and 21mm cushions. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore.
The dual-rod design provides high anti-rotation stability and allows the back rod to carry a sensor cam, driving two tools simultaneously. With a 1402 N @0.5 MPa output, the computed safe working load is about 841 N (60%), enabling a vertical lift of approximately 71 kg with a 2:1 margin. This SUD63X170S includes a magnet (-S) for legacy CS1-B/DS1-B switches; the SAUD replacement upgrades to current CMSG/DMSG/EMSG sensors while retaining FA/LB mounting.

The SAUD63X170S 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 pick-and-place tools simultaneously from a single 63mm bore body, utilising the equal both-ways force for balanced horizontal transfer.
The twin rods prevent piston rotation during rapid diverting strokes on a packaging line, ensuring the end-of-arm tooling stays perfectly aligned.
Uses the extended back rod to carry a sensor cam, confirming gate position in a high-speed sorting chute while the front rod actuates the flap.
To replace the discontinued SUD63X170S, specify the SAUD63X170S drop-in: it matches the 63mm bore, 170mm stroke, 3/8" port, and FA/LB mounting. When sizing both ways, verify the equal force fits your load, or step to neighbouring bores (50mm or 80mm) if a different capacity is needed. A double rod is right when you need anti-rotation rigidity or a rear cam for sensors. For the -S suffix, plan a sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. At 170mm stroke, side-load is minimal, but for any stroke >=300mm, ensure guide alignment to prevent rod binding. A plain cylinder does not hold loads on air loss; use an external rod lock for held loads.
Replacement checklist
Yes, the SUD63X170S is discontinued. The exact drop-in replacement is the SAUD63X170S, which shares the same 63mm bore, 170mm stroke, 3/8" port, and FA/LB mounting. You will only need to upgrade the sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG.
Because it is a double-rod cylinder, the force is equal both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. It operates at 30-800 mm/s with a 21mm adjustable cushion at each end.
