This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X150SCMLB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X150SCMLB 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X150SCMLB
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150SCMLB is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X150SCMLB, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150SCMLB
The AirTAC MAL20X150SCMLB is a discontinued compact double-acting aluminum mini round cylinder. Delivering 157 N of push force at 0.5 MPa, it features a 20 mm bore, a 150 mm stroke, and a built-in magnet. The exact drop-in replacement is the MBL20X150SCMLB, which matches the original bore, stroke, output force, G1/8 port, and LB mounting footprint.
This legacy unit uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for equal durability. The -S magnet on this MAL works with older CS1-M or DS1-M switches, but upgrading to the MBL requires the current CMSG, DMSG, or EMSG sensor family. The internal piston relies on a heterogeneous two-way grease-retaining seal, and the rod is 8 mm carbon steel with 20 um hard chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X150SCMLB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 kgf | |
The MBL20X150SCMLB 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X150SCMLB Is Used
PCB Depaneling Ejector
Provides 157 N of push at 0.5 MPa to safely eject cut PCB panels from a router machine fixture without damaging traces.
Connector Insertion Press
Drives a 150 mm stroke to push Molex connectors into PCB headers, using the -S magnet for position confirmation.
Small Carton Flap Folder
Uses the CM round-end and LB foot mount to articulate a folding arm that closes lightweight cardboard flaps in packaging lines.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150SCMLB with MBL20X150SCMLB
To replace the MAL20X150SCMLB, order the MBL20X150SCMLB and verify your fittings. This SKU includes a CM round-end back cover and an LB foot mounting bracket. The port thread is PT (tapered). Because the -S magnet is present, you must swap your existing CS1-M or DS1-M switches for CMSG, DMSG, or EMSG sensors to maintain rod position detection.
For sizing flexibility, stepping down to the 12 mm bore yields less force, while stepping up to the 25 mm bore provides 245 N push at 0.5 MPa. At 150 mm of stroke, the 8 mm rod has low side-load tolerance, so use the LB foot mount to support the body or add an external guide rail. The fixed rubber bumper softens end-of-stroke impact but does not lock the rod; if air drops, the load drifts. For adjustable air cushioning, step up to the MBLC series.
Upgrade checklist
- ✓ Order the MBL20X150SCMLB (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 MBL20X150SCMLB instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150SCMLB FAQ
Yes, the MAL20X150SCMLB is discontinued. The exact drop-in replacement is the MBL20X150SCMLB, which matches the 20 mm bore, 150 mm stroke, G1/8 port, CM cover, and LB mount. You will need to update your sensors from the older CS1-M or DS1-M to the CMSG, DMSG, or EMSG family.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force is 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion; for adjustable cushioning, use the MBLC.
