This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X125-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X125-S-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 MAL32X125-S-U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X125-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 125mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X125-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X125-S-U
The AirTAC MAL32X125-S-U is a discontinued double-acting aluminum mini round cylinder with a 32mm bore and 125mm stroke. It delivers 402N of push force and 346N of pull force at 0.5MPa. The exact drop-in replacement is the MBL32X125-S-U, which matches the original bore, stroke, output force, G1/8 port, and flat-end mounting. The legacy MAL uses a threaded front and back cover assembly, whereas the modern MBL features a riveted rolling-packed body for equally robust performance.
This specific SKU includes a built-in magnet (-S) for position sensing and a U-style flat-end back cover for rigid rear mounting. On the MAL, the magnet interfaces with older CS1-M or DS1-M reed switches; upgrading to the MBL requires switching to the current CMSG, DMSG, or EMSG sensor families. Internally, a heterogeneous two-way seal retains grease, and the 12mm carbon-steel rod features 20um hard-chrome plating to resist wear. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts, as it lacks an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X125-S-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 | — |

Where the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X125-S-U Is Used
PCB Router Gating
Actuates a routing lane diverter on a PCB depaneling conveyor, using the 125mm stroke to shift the gate and the 402N push force to hold position against passing board carriers.
Centrifuge Tube Ejection
Pushes capped 50ml centrifuge tubes out of a heating block in a lab automation carousel, relying on the 346N pull force to retract the 12mm rod cleanly without binding.
Carton Flap Folder
Folds the minor flaps on small pharmaceutical cartons prior to sealing, where the compact 32mm body fits tightly between side rails and the U flat-end mounts rigidly to the frame.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X125-S-U with MBL32X125-S-U
To replace the MAL32X125-S-U, order the MBL32X125-S-U. Confirm your 32mm bore, 125mm stroke, G1/8 port, PT thread, flat-end U back cover, and magnet requirement. Because the -S magnet is present, you must replace older CS1-M or DS1-M switches with CMSG, DMSG, or EMSG sensors for the MBL body. If your application requires adjustable end-cushioning to absorb kinetic energy, step up to the MBLC variant on the current line, as the MAL only offers a fixed rubber bumper.
When sizing, verify if 32mm is the optimal bore. Stepping down to the 25mm bore yields 245N push at 0.5MPa, while stepping up to the 40mm bore provides 628N push. Note that a plain MAL or MBL cylinder does not hold its position if air pressure drops; the rod will drift. For suspended loads, install an external pilot-operated check valve. At 125mm stroke, side-load tolerance is moderate, but the 12mm rod is susceptible to bending if misaligned—ensure the U flat-end rear is perfectly square to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBL32X125-S-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 MBL32X125-S-U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X125-S-U FAQ
Yes, the MAL32X125-S-U is discontinued. The exact drop-in replacement is the MBL32X125-S-U. It offers the same 32mm bore, 125mm stroke, G1/8 port, and flat-end U mounting. The main difference is the body construction: the MAL uses threaded covers while the MBL uses a riveted rolling-packed body. Additionally, if you use the -S magnet for position sensing, you must upgrade from the older CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG sensor family.
At 0.5 MPa, the 32mm bore provides 402N of push force and 346N of pull force. At 0.7 MPa, the push force increases to 563N. The maximum theoretical force is 82 kgf at 1.0 MPa. The cylinder operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s.
