This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X100-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X100-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 MAL32X100-S-U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X100-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X100-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X100-S-U
The AirTAC MAL32X100-S-U is a discontinued double-acting aluminum mini round cylinder engineered to deliver 402 N of push force at 0.5 MPa. Featuring a 32 mm bore and a 100 mm stroke, this compact actuator utilizes a Ø12 mm carbon-steel rod with 20 um hard-chrome plating. The U designation indicates a flat-end back cover for rigid, straight-line mounting. Its internal piston relies on a heterogeneous two-way seal designed to retain grease, while a self-lubricating bearing guide in the front cover minimizes friction.
Because the MAL series has reached end-of-life, the exact drop-in replacement is the MBL32X100-S-U, which matches the original bore, stroke, output force, G1/8 port, and mounting interface. A key structural change occurred in the upgrade: the legacy MAL uses threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body. Furthermore, the -S magnet on this MAL unit functions with the older CS1-M and DS1-M reed switches; if you transition to the MBL, you must update to the current CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X100-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 | — |
| Max (@1.0 MPa) | 82 kgf | |
The MBL32X100-S-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 MAL32X100-S-U Is Used
PCB Router Ejection
Provides 402 N of push force at 0.5 MPa to eject cut printed circuit boards from a routing fixture without damaging delicate traces.
Connector Insertion Press
Drives a 100 mm stroke to seat multi-pin ribbon connectors into housing blocks, relying on the rigid U flat-end cover to maintain perpendicular alignment.
Carton Flap Folder
Actuates a mechanical arm to fold small corrugated carton flaps, using the self-lubricating bearing guide to handle rapid 30-800 mm/s cycling.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X100-S-U with MBL32X100-S-U
To replace the MAL32X100-S-U, order the MBL32X100-S-U and verify your setup accommodates the G1/8 port and M10x1.25 rod-end thread. Since this SKU includes the -S magnet and U flat-end back cover, you will retain rigid mounting but must swap any legacy CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches. If your application requires less force, stepping down to the 25 mm bore yields 245 N of push at 0.5 MPa. If you need more power, stepping up to the 40 mm bore provides 628 N at 0.5 MPa.
Keep in mind that the fixed rubber bumper absorbs end-of-stroke impact but is not an adjustable air cushion; for deceleration control on the current line, look at the MBLC variant. Additionally, a plain cylinder does not hold its position if air pressure drops—the rod will drift. Implement an external rod lock or pilot-operated check valve if load holding is critical. At 100 mm stroke, side-load risk is moderate, but the small Ø12 mm rod still demands careful alignment to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBL32X100-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 MBL32X100-S-U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X100-S-U FAQ
Yes, the MAL32X100-S-U is discontinued. The exact drop-in replacement is the MBL32X100-S-U, offering identical bore, stroke, force, port, and mounting. Note that the MBL uses a riveted body instead of threaded covers, and you must upgrade your -S magnet sensors from CS1-M/DS1-M to the CMSG/DMSG/EMSG series.
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
