This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X40SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X40SU in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X40SU
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X40SU is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 40mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X40SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X40SU
The AirTAC MAL32X40SU is a discontinued double-acting aluminum mini round cylinder with a 32 mm bore and 40 mm stroke. It delivers 402 N of push force at 0.5 MPa. The exact drop-in replacement is the MBL32X40SU, which matches the bore, stroke, output force, G1/8 port, and U flat-end back cover for a seamless retrofit.
This legacy SKU includes a built-in magnet (-S) for position detection. On the MAL, this magnet pairs with older CS1-M or DS1-M reed switches, whereas the modern MBL replacement requires CMSG, DMSG, or EMSG sensors. The original MAL body uses threaded front and back covers, while the upgraded MBL features a riveted rolling-packed body. Both designs rely on a fixed rubber bumper at the stroke ends rather than an adjustable air cushion.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X40SU Technical Specifications

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X40SU 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 MBL32X40SU 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.

Where the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X40SU Is Used
Pouch Sealing Jaws
Actuates the sealing bars on a vertical form-fill-seal machine, using the 40 mm stroke to close heated jaws rapidly with 402 N of force.
PCB Router Gating
Diverts printed circuit boards exiting a depaneling router, relying on the compact 32 mm body to fit within tight electronics assembly cells.
Carton Flap Folding
Folds minor flaps on small pharmaceutical cartons prior to case packing, where the U flat-end cover mounts rigidly to the machine frame.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X40SU with MBL32X40SU
To replace the MAL32X40SU, order the MBL32X40SU and transfer your existing mounting hardware. Confirm the U flat-end back cover, PT port thread, and magnet requirement. Because this SKU has the -S magnet, you must also upgrade your sensing switches from the legacy CS1-M / DS1-M family to the current CMSG / DMSG / EMSG family. If your application requires an adjustable air cushion rather than the standard fixed rubber bumper, step up to the MBLC32X40SU on the current line.
When sizing, verify if 402 N of push at 0.5 MPa is optimal. Stepping down to a 25 mm bore drops the push force to 245 N, while stepping up to a 40 mm bore increases it to 628 N. Note that a plain MAL or MBL cylinder does not hold a load if air pressure is lost; the rod will drift. Use an external rod lock or pilot-operated check valve for secure position holding.
Upgrade checklist
- ✓ Order the MBL32X40SU (same bore/stroke/force)
- ✓ Same G1/8 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the MBL32X40SU instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X40SU FAQ
Yes, the MAL32X40SU is discontinued. The exact drop-in replacement is the MBL32X40SU, offering the same 32 mm bore, 40 mm stroke, G1/8 port, and U flat-end mounting. Note that if you use the -S magnet for position detection, you must upgrade from the old CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG sensors.
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
