This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X150-S-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X150-S-CA 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 MAL20X150-S-CA
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CA 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 MBL20X150-S-CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CA
The AirTAC MAL20X150-S-CA is a discontinued compact double-acting aluminum mini round cylinder. It delivers 157N of push force at 0.5 MPa and uses a G1/8 port with an Ø8mm rod. AirTAC replaced this legacy unit with the MBL20X150-S-CA, a drop-in alternative retaining the exact 20mm bore, 150mm stroke, output force, port size, and CA pivot mounting.
This SKU includes a built-in magnet (-S) for position sensing and a CA pivot back cover that swings on a pin to absorb arcing motion. The original MAL uses threaded front and back covers, whereas the MBL replacement features a riveted rolling-packed body. Additionally, the -S magnet on this cylinder pairs with older CS1-M or DS1-M switches, while the MBL successor utilizes the current CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X150-S-CA 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 MBL20X150-S-CA 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 MAL20X150-S-CA Is Used
PCB Depanelling Router Gates
Actuates a pivoting routing gate to separate composite PCB panels, using the 150mm stroke and CA clevis to swing the tooling arm out of the work zone.
Semiconductor Wafer Cassette Tilt
Tilts a wafer processing cassette at an angle for robot loading, where the 157N push force at 0.5 MPa is sufficient to pivot the lightweight aluminum fixture.
Packaging Flap Folder
Folds cardboard carton flaps on a continuous flow wrapper, relying on the fixed rubber bumper to absorb the repeated end-of-stroke impacts.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CA with MBL20X150-S-CA
To replace the MAL20X150-S-CA, order the MBL20X150-S-CA. Confirm your 150mm stroke, G1/8 port, PT tapered thread, and CA clevis pivot are retained. If you need to step down, the 20mm bore offers 157N push at 0.5 MPa, while the neighboring 25mm bore provides 245N. If you need to step up, the 32mm bore yields 402N. Because this model lacks an adjustable cushion, relying solely on a fixed rubber bumper, consider the current-line MBLC if you need end-of-stroke air cushioning.
At 150mm of stroke, the small Ø8mm carbon-steel rod has low side-load tolerance. Use the CA pivot bracket to accommodate arcing loads, or add an external guide to prevent rod bending. Remember that a plain cylinder does not hold its position when air is lost; the bumper only softens the stroke end, so add an external rod lock or pilot-operated check valve for load holding.
Upgrade checklist
- ✓ Order the MBL20X150-S-CA (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 MBL20X150-S-CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-CA FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL20X150-S-CA. It matches the 20mm bore, 150mm stroke, CA pivot mounting, and G1/8 port. The main upgrade is the body construction (riveted rolling-packed body instead of threaded covers) and the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The bore 20mm double-acting cylinder provides a push force of 157N and pull force of 132N at 0.5 MPa. At 0.7 MPa, the push force is 220N, with a maximum theoretical force of 32 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
