This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X150S 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 SUD100X150S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X150S is a double-acting profile-type standard cylinder with a Ø100mm bore and 150mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X150S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X150S
The AirTAC SUD100X150S is a discontinued double-acting double-rod profile cylinder featuring a 100mm bore and 150mm 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 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The exact drop-in replacement is the SAUD100X150S, sharing the same bore, stroke, 1/2 inch port, and mounting. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the rear rod can carry a sensor cam or drive two tools simultaneously, the double-rod design offers excellent anti-rotation stability. With a 3681 N force at 0.5 MPa, the computed safe working load is roughly 2209 N, translating to a vertical lift capacity of about 188 kg with a 2:1 margin. This -S model includes a piston magnet for legacy CS1-B/DS1-B switches, though the SAUD replacement upgrades to current CMSG/DMSG/EMSG sensors. A plain cylinder does not hold loads on air loss; the 29mm adjustable air cushion only decelerates near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X150S 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 SAUD100X150S 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.

| 100 | Bore size in mm. |
| ×150 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUD100X150S Is Used
Dual-Station Transfer
Drives two opposing workpieces simultaneously from one piston, utilising the equal both ways force to push and pull parts across two machining stations.
Anti-Rotation Pusher
The twin-rod profile prevents mechanical twist during high-speed horizontal pushing on a conveyor line, maintaining precise alignment without external guides.
Symmetric Lifting Jig
Lifts and lowers a rigid pallet jig using both rod ends, balancing the 188 kg vertical lift capacity evenly to prevent cantilever sag on the tooling plate.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X150S with the SAUD100X150S
To replace the discontinued SUD100X150S, select the drop-in SAUD100X150S, which matches the 100mm bore, 150mm stroke, M20x1.5 rod thread, and FA/LB mounting. When sizing both ways, verify the equal push/pull force fits your application, checking neighbouring bores if you need less force. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one piston. The -S suffix means you must change legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG on the SAUD. For strokes of 300mm or longer, carefully manage side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X150S
- ✓ 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 SUD100X150S FAQ
Yes, the SUD100X150S is discontinued. The exact drop-in replacement is the SAUD100X150S, which matches the 100mm bore, 150mm stroke, 1/2 inch port, and FA/LB mounting. You only need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. Operating speed ranges from 30 to 800 mm/s, and the 1/2 inch port bore operates safely up to a maximum pressure of 1.0 MPa.
