This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X450-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X450-U 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 MAL32X450-U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X450-U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 450mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X450-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X450-U
The AirTAC MAL32X450-U is a discontinued double-acting aluminum mini round cylinder featuring a 32mm bore and 450mm stroke. It delivers 402N of push force and 346N of pull force at 0.5MPa, using a G1/8 port and an M10x1.25 rod-end thread. The exact drop-in replacement is the MBL32X450-U, which matches the original bore, stroke, output force, port, and mounting footprint exactly.
This legacy SKU uses a U flat-end back cover for rigid rear mounting and lacks a magnet, meaning it cannot support any position sensing. The original MAL body relied on threaded front and back covers, whereas the modern MBL upgrade features a riveted rolling-packed body. Both generations use a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X450-U 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 MBL32X450-U 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 MAL32X450-U Is Used
PCB Handling Gate
Actuates a 450mm routing flap on a conveyor line diverting populated circuit boards, utilizing the 402N push force at 0.5MPa to overcome guide friction.
Carton Sorting Pusher
Extends across a packaging belt to reject misaligned small cartons, relying on the rigid U flat-end back cover to maintain alignment during the 450mm travel.
Textile Yarn Guide
Traverses a yarn tensioning carriage 450mm to layer threads evenly, taking advantage of the 30-800mm/s speed range without needing position sensors.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X450-U with MBL32X450-U
To replace the MAL32X450-U, order the MBL32X450-U and verify your 32mm bore, 450mm stroke, G1/8 port, and PT thread form. Because this SKU has no -S magnet, it cannot accept a sensor; if you now require position feedback, you must step up to an MBL32X450S and switch to the modern CMSG, DMSG, or EMSG switch family, as the old CS1-M and DS1-M sensors are obsolete. If you need to adjust your force output, stepping down to the 25mm bore yields 245N push at 0.5MPa, while stepping up to the 40mm bore provides 628N push at 0.5MPa.
At a 450mm stroke, the 12mm carbon-steel rod is highly susceptible to bending under side loads; you must use an external guide rail or a pivot mounting accessory to prevent premature seal failure. Note that the fixed rubber bumper softens impact but does not lock the rod, so a pilot-operated check valve is required to hold a suspended load during air loss. If your application demands precise end-of-stroke deceleration, upgrade to the current-line MBLC32X450-U which offers an adjustable air cushion.
Upgrade checklist
- ✓ Order the MBL32X450-U (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 MBL32X450-U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X450-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL32X450-U, which shares the same 32mm bore, 450mm stroke, G1/8 port, and U flat-end mounting. The main upgrade change is the body construction, moving from threaded covers on the MAL to a riveted rolling-packed body on the MBL.
At 0.5MPa it provides 402N push and 346N pull force, 563N push at 0.7MPa, and a maximum theoretical force of 82kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept any position sensor; if sensing is required, you must order the MBL32X450S and use CMSG, DMSG, or EMSG switches.
