This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X225S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X225S 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 SUD100X225S is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X225S, which matches its bore, stroke, force and mounting.
The AirTAC SUD100X225S is a double-acting, double-rod profile cylinder featuring a 100mm bore and 225mm stroke. A rod exits both ends on a single piston, meaning push and pull force are equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This discontinued model uses an extruded aluminium profile barrel and a 1/2 inch air port. The exact drop-in replacement is the SAUD100X225S, which matches the bore, stroke, force, port, and FA/LB mounting.
Because the second rod drives a sensor cam and resists rotation, it is ideal for multi-tool tasks. The S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; the SAUD upgrade uses current CMSG/DMSG/EMSG sensors. Based on the 3681 N @0.5 MPa figure, the safe working load is about 2209 N, yielding a vertical lift capacity of roughly 188 kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the air cushion only decelerates, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X225S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X225S 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 maintain perfectly balanced cutting pressure.
Uses the twin rods exiting both ends to prevent mechanical rotation during part diversion on a high-speed packaging line.
Lifts a 188 kg vertical payload using the back rod to carry a sensor cam for mid-stroke positioning without external brackets.
To replace the discontinued SUD100X225S, specify the SAUD100X225S drop-in: it preserves the 100mm bore, 225mm stroke, equal both ways force, 1/2 inch port, and FA/LB mounting. Size both ways by checking neighbouring bores (80mm or 63mm) against your exact force needs. Choose a double-rod cylinder when you need anti-rotation, a back rod to carry a sensor cam, or to drive two tools. If upgrading, swap the -S legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For this 225mm stroke (under 300mm), side-load alignment is less critical, but always guide the rod end.
Replacement checklist
Yes, the SUD100X225S is discontinued. The exact drop-in replacement is the SAUD100X225S, which matches the 100mm bore, 225mm stroke, equal both ways force, 1/2 inch port, and FA/LB mounting.
Because it is a double-rod cylinder, force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It operates at 30-800 mm/s, uses a 1/2 inch port, and has a 29mm adjustable air cushion at each end.
