This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X145CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X145CA 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 MAL20X145CA
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X145CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 145mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X145CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X145CA
The AirTAC MAL20X145CA is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 145mm stroke. It delivers 157N of push force and 132N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL20X145CA, which matches the bore, stroke, output force, G1/8 port, and CA mounting exactly.
This legacy unit features a CA pivot clevis back cover designed to swing on a pin for arcing loads. It uses a fixed rubber bumper for end-of-stroke damping and lacks a magnet, meaning it cannot accept a position sensor. The original MAL body used threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for greater structural integrity.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X145CA 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 MBL20X145CA 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 MAL20X145CA Is Used
Textile Loom Guide
Drives a 145mm thread guide arm on a textile loom, using the 157N push force to shift yarn carriers while the CA clevis absorbs pivot arc.
Package Flap Diverter
Actuates a 145mm routing flap on a packaging conveyor, where the compact 20mm body fits between tight roller supports.
PCB Edge Tester
Positions a testing probe over a moving PCB conveyor, relying on the 132N pull force to safely retract the delicate probe head.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X145CA with MBL20X145CA
To replace this MAL20X145CA, order the MBL20X145CA. Confirm your 145mm stroke, G1/8 port, PT tapered thread, and CA pivot back cover. Because this SKU lacks an -S magnet, it cannot support a sensor; if you need position detection, step up to an MBL20X145SCA and note that the MBL line requires modern CMSG, DMSG, or EMSG switches instead of the legacy CS1-M or DS1-M.
For sizing flexibility, stepping down to the 20mm bore offers 157N push at 0.5 MPa, while stepping up to the 25mm bore provides 245N. At 145mm of stroke, the 8mm rod has low side-load tolerance; use the CA clevis to absorb radial arc or add an external guide. A plain bumper does not hold loads when air is lost, so use an external rod lock for safety. If you need adjustable cushioning, specify the MBLC20X145CA instead of the standard MBL.
Upgrade checklist
- ✓ Order the MBL20X145CA (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 MBL20X145CA instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X145CA FAQ
Yes, the MAL20X145CA is discontinued. The exact drop-in replacement is the MBL20X145CA, offering the same 20mm bore, 145mm stroke, force, G1/8 port, and CA pivot mount.
At 0.5 MPa it provides 157N push and 132N pull, 220N push at 0.7 MPa, and a maximum of 32 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot take a position sensor.
