This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X50-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X50-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 MAL20X50-CA
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X50-CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 50mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X50-CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X50-CA
The AirTAC MAL20X50-CA is a discontinued compact double-acting aluminum mini round cylinder. Designed for tight spaces, it delivers 157 N of push force at 0.5 MPa. The exact drop-in replacement is the MBL20X50-CA, which matches the 20 mm bore, 50 mm stroke, G1/8 port, and CA pivot mounting.
This legacy unit features a CA pivot clevis back cover for arcing loads and a fixed rubber bumper. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X50-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 MBL20X50-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 MAL20X50-CA Is Used
PCB Router Gantry
Drives the Z-axis plunge on a small desktop PCB router, where the 157 N push force at 0.5 MPa easily cuts 1oz copper clad and the CA clevis absorbs gantry misalignment.
IC Tube Sorting
Pushes surface-mount integrated circuit tubes into test bins, utilizing the compact 20 mm bore and 50 mm stroke to fit within densely packed semiconductor handling racks.
Carton Flap Tucking
Tucks minor flaps on small pharmaceutical cartons, relying on the self-lubricating front-cover bearing guide to maintain smooth motion without external grease.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X50-CA with MBL20X50-CA
To replace the MAL20X50-CA, order the MBL20X50-CA. Confirm your 50 mm stroke, G1/8 port, and PT thread form. The CA pivot back cover swings on a pin to absorb arcing loads, so ensure your clevis pin is intact. If you need to step up force, the 25 mm bore offers 245 N push at 0.5 MPa; if you need less, note 20 mm is the smallest available size. The fixed rubber bumper softens end-of-stroke impact but is not an adjustable cushion—choose the MBLC line if you need adjustable air cushions. Since this SKU has no -S magnet, it cannot support a sensor; if you need position detection, order an MBL20X50S-CA and use the current CMSG or DMSG switches.
Upgrade checklist
- ✓ Order the MBL20X50-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 MBL20X50-CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X50-CA FAQ
Yes, the MAL20X50-CA is discontinued. The exact drop-in replacement is the MBL20X50-CA, offering the same 20 mm bore, 50 mm stroke, G1/8 port, and CA pivot mounting. The MBL upgrades the body to a riveted rolling-packed design, but all performance ratings remain identical.
At 0.5 MPa it provides 157 N push and 132 N pull force; at 0.7 MPa it pushes 220 N, with a theoretical maximum of 32 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept a position sensor. If you need detection, order the MBL20X50S-CA and use CMSG or DMSG switches.
