This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X37U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X37U 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 MAL32X37U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X37U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 37mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X37U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X37U
The AirTAC MAL32X37U is a discontinued double-acting aluminum mini round cylinder. It delivers a 402 N push force at 0.5 MPa through a 32 mm bore and 37 mm stroke. The exact drop-in replacement is the MBL32X37U, which shares the same force, G1/8 port, and U flat-end rear cover. This original MAL unit features threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body for equivalent ratings.
Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20 um hard chrome plating to resist wear. End-of-travel impact is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X37U 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 MBL32X37U 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 MAL32X37U Is Used
PCB Depaneling Router
Provides 402 N of push at 0.5 MPa to drive a cutting bit through rigid FR4 fiberglass panels in tight electronics assembly cells.
Carton Flap Folder
Uses the 37 mm stroke to tuck minor flaps on small packaging lines, relying on the U flat-end cover for rigid, straight-line mounting.
Microplate Lid Press
Snaps thin plastic lids onto 96-well microplates using a 346 N pull force, fitting easily into compact laboratory automation frames.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X37U with MBL32X37U
To replace the MAL32X37U, order the MBL32X37U and confirm the PT thread, G1/8 port, and U flat-end back cover. If you need a position sensor, you must step up to an MBL32X37US, as this base model cannot mount one. If your application requires adjustable end-cushioning, select the MBLC32X37U instead of the standard bumper. Stepping down to the 25 mm bore yields 245 N push force, while stepping up to the 40 mm bore provides 628 N. A plain cylinder drifts when air is lost; use a pilot-operated check valve for load holding.
Upgrade checklist
- ✓ Order the MBL32X37U (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 MBL32X37U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X37U FAQ
Yes, the MAL32X37U is discontinued. The exact drop-in replacement is the MBL32X37U, which matches the 32 mm bore, 37 mm stroke, G1/8 port, and U flat-end cover. The new MBL uses a riveted body instead of threaded covers.
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
