This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X120 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X120 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 SUD32X120
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X120 is a double-acting profile-type standard cylinder with a Ø32mm bore and 120mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X120, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X120
The AirTAC SUD32X120 is a double-acting, double-rod profile cylinder featuring an extruded aluminium barrel that is more compact than an ISO 15552 unit of the same bore. Because a rod exits both ends on a single piston, the push and pull forces are perfectly equal both ways, rated at 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. This specific SUD model is discontinued and is directly replaced by the SAUD32X120, which retains the exact 32 mm bore, 120 mm stroke, 1/8" port, and SC-series FA/LB mounting compatibility.
This non-magnetic SKU lacks a piston magnet and cannot accept position switches, whereas the modern SAUD replacement utilises current CMSG/DMSG/EMSG sensors (the SUD used legacy CS1-B/DS1-B). The dual-rod design provides inherent anti-rotation properties and allows the rear rod to drive a secondary tool. For sizing, the 345 N force at 0.5 MPa yields a safe working load of roughly 207 N (60% derating) and a vertical lift capacity of about 18 kg with a 2:1 safety margin. Note that air cushions only decelerate the piston near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X120 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 SAUD32X120 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 SUD32X120 Is Used
Dual-End Transfer Pusher
Simultaneously pushes a product from both ends on a conveyor line, utilising the equal both-ways force to keep movement perfectly synchronized without twisting.
Anti-Rotation Clamping Unit
Clamps irregularly shaped machined parts securely. The twin-rod architecture prevents piston rotation during the clamping cycle, ensuring precise alignment.
Synchronized Tool Drive
Drives a primary cutting tool on the front rod while the rear rod actuates a secondary material guide, doubling operational efficiency from one compact profile body.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X120 with the SAUD32X120
To replace the discontinued SUD32X120, select the drop-in SAUD32X120, which matches the 32 mm bore, 120 mm stroke, equal-both-ways force, 1/8" port, and FA/LB mounting. When sizing both ways, verify if neighbouring bores offer better margins: the 345 N equal force at 0.5 MPa provides a safe load of 207 N, but if your application requires more thrust, step up to the 40 mm bore (528 N). A double-rod configuration is ideal when you need anti-rotation stability or must drive two tools simultaneously from one piston. Because this specific SKU is non-magnetic, it cannot accept sensors; upgrading to the SAUD allows the use of modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, carefully manage side-load moments to prevent guide bushing wear. Finally, remember that air cushions only decelerate the piston; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X120
- ✓ 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 SUD32X120 FAQ
Yes, the AirTAC SUD32X120 is discontinued. The exact drop-in replacement is the SAUD32X120, which shares the same 32 mm bore, 120 mm stroke, 1/8" port, and FA/LB mounting. The SAUD upgrade also introduces the SAUF built-in-valve variant and uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The SUD32X120 features a 1/8" air port and delivers equal force both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with adjustable air cushions (21 mm) at each end that decelerate the piston near stroke end.
