This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X100S 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 SUD32X100S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X100S is a double-acting profile-type standard cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X100S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X100S
The AirTAC SUD32X100S is a double-acting, double-rod profile cylinder featuring a 32mm bore and 100mm stroke. Because a rod exits both ends on one piston, push and pull force is equal both ways at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. This discontinued model used a built-in piston magnet for legacy CS1-B/DS1-B switches and has a 1/8" port. The exact drop-in replacement is the SAUD32X100S, which shares the same body, bore, stroke, force, and FA/LB mounting.
The dual-rod design prevents piston rotation and allows driving two tools simultaneously from one compact aluminum profile barrel. For sizing, a safe working load is roughly 207 N (60% of the 345 N @0.5 figure), translating to a vertical lift capacity of about 18 kg with a 2:1 margin. Note that air cushions only decelerate near stroke end; an external rod lock is required for load holding on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUD32X100S 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.

| -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 SUD32X100S Is Used
Dual-Tool Transfer
Drives two opposing pick-and-place grippers simultaneously from one compact body, utilizing the equal both ways force to maintain synchronous tool acceleration.
Anti-Rotation Lift
Lifts guided vertical loads up to 18 kg using the twin rods to prevent piston twist and binding without external linear bearings.
Symmetric Pushing
Pushes a workpiece from one side while retracting an opposing fixture at the exact same speed and 345 N @0.5 MPa force.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X100S with the SAUD32X100S
To replace the discontinued SUD32X100S, install the drop-in SAUD32X100S, which preserves the 32mm bore, 100mm stroke, 1/8" port, and equal-both-ways force. When sizing both ways, verify that 345 N @0.5 MPa meets your dynamic load, or step up to a 40mm bore neighbor if more force is needed; step down if friction is excessive. Choose a double-rod configuration when anti-rotation or dual-tool driving is required. Mounting is limited to Basic, FA, and LB (SC-series compatible only). For the -S magnet option, change from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For this 100mm stroke, ensure side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X100S
- ✓ 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 SUD32X100S FAQ
Yes, the SUD32X100S is discontinued. The exact drop-in replacement is the SAUD32X100S, which matches the 32mm bore, 100mm stroke, 1/8" port, and FA/LB mounting. You only need to upgrade the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. Operating speed ranges from 30-800 mm/s. A safe working load is approximately 207 N at 0.5 MPa.
