This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X175S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X175S 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.
Airtac SUD Series Double Rod Cylinder SUD100X175S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X175S is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X175S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X175S
The AirTAC SUD100X175S is a double-acting, double-rod profile cylinder featuring a 100mm bore and 175mm stroke. A rod exits both ends on a single piston, meaning push and pull forces are equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. Built with an extruded aluminium profile barrel, it is notably shorter than an ISO 15552 cylinder of the same bore. This SUD100X175S model is discontinued and the exact drop-in replacement is the SAUD100X175S, retaining the identical 1/2" port, M20x1.5 rod thread, and 29mm adjustable cushions.
Because the rear rod can carry a sensor cam or drive two tools simultaneously while resisting rotation, the double-rod architecture offers distinct mechanical advantages. With a 0.5 MPa operating pressure, the computed safe working load is roughly 2209 N (60% of the force figure), translating to a vertical lift capacity of about 188 kg with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAUD100X175S requires current CMSG/DMSG/EMSG sensors. Note that a plain cylinder does not hold loads on air loss—the cushion only decelerates near stroke end, so an external rod lock is needed for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X175S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X175S 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.
Where the Airtac SUD Series Double Rod Cylinder SUD100X175S Is Used
Dual-Station Machining
Drives two opposing workstations simultaneously from one piston, ensuring perfectly synchronized part clamping and milling operations with equal push and pull force.
Anti-Rotation Transfer
Transfers components across a conveyor belt without rotational drift, using the dual-rod geometry to maintain precise part orientation during high-speed indexing.
Symmetric Lifting Jig
Lifts heavy pallets or fixtures symmetrically from both ends, preventing binding in vertical lift guides by distributing the 3681 N force evenly across the tool.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X175S with the SAUD100X175S
To replace the discontinued SUD100X175S, specify the SAUD100X175S as a direct drop-in solution, matching the 100mm bore, 175mm stroke, equal-both-ways force, 1/2" port, and Basic/FA/LB mounting. When sizing both ways, verify the 3681 N @0.5 MPa force fits your load, or step to neighbour bores if more capacity is needed. Choose a double-rod cylinder when anti-rotation stability or driving two tools from one piston is required. If upgrading, change legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG equivalents. For stroke lengths >=300, verify side-load limits to prevent guide wear. For suspended loads, add an external rod lock because cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X175S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUD Series Double Rod Cylinder SUD100X175S FAQ
Yes, the SUD100X175S is discontinued. The exact drop-in replacement is the SAUD100X175S, which matches the 100mm bore, 175mm stroke, 1/2" port, and Basic/FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches.
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. The air port is 1/2" (PT thread default), the rod is Ø25mm with an M20x1.5 thread, and speed ranges from 30-800 mm/s.
