This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X155CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X155CA 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 MAL20X155CA
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X155CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 155mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X155CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X155CA
The AirTAC MAL20X155CA is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 155mm stroke. It delivers 157N push and 132N pull at 0.5MPa. AirTAC replaced this series with the MBL20X155CA, a drop-in upgrade retaining the exact bore, stroke, force, G1/8 port, and CA pivot mounting.
This legacy model features threaded front and back covers, whereas the MBL replacement uses a riveted rolling-packed body. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. The rod is 8mm carbon-steel with 20um hard chrome, guided by a self-lubricating bearing and a heterogeneous two-way grease-retaining seal.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X155CA 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 MBL20X155CA 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 MAL20X155CA Is Used
PCB Depaneling Routing
Drives a routing blade across a 155mm path to singulate PCB panels, utilizing the 157N push force to slice through substrate materials cleanly.
Pick-and-Place Z-Axis
Actuates a small vacuum gripper over a 155mm vertical travel distance, moving light electronic components between conveyor belts.
Carton Flap Folding
Pushes corrugated cardboard flaps into position at the sealing station, where the CA pivot absorbs slight angular misalignments.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X155CA with MBL20X155CA
To replace the MAL20X155CA, order the MBL20X155CA, ensuring your CA pivot back cover and PT porting match. If you need to step down, the neighboring 12mm bore yields 45N push at 0.5MPa; stepping up to the 25mm bore provides 245N. For 155mm strokes, the small 8mm rod has low side-load tolerance, so use the CA clevis to allow arcing movement or add an external guide. The fixed rubber bumper softens stroke ends, but if you need adjustable cushioning, look to the MBLC variant. A plain MBL does not hold loads when air is lost.
Upgrade checklist
- ✓ Order the MBL20X155CA (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 MBL20X155CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X155CA FAQ
Yes, the MAL20X155CA is discontinued. The exact drop-in replacement is the MBL20X155CA, which matches the 20mm bore, 155mm stroke, G1/8 port, and CA pivot mounting. The MBL uses a riveted body instead of threaded covers.
At 0.5MPa, the push force is 157N and pull is 132N. At 0.7MPa, push is 220N, with a theoretical max of 32kgf at 1.0MPa. Because this SKU lacks the -S magnet, it cannot accept CS1-M or DS1-M sensors; the MBL replacement uses CMSG/DMSG/EMSG switches.
