This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X145SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X145SU 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 MAL20X145SU
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X145SU 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 MBL20X145SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X145SU
The AirTAC MAL20X145SU is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 145mm stroke. It delivers 157N push and 132N pull force at 0.5 MPa, utilizing a rigid U flat-end back cover. AirTAC replaced this legacy unit with the MBL20X145SU drop-in replacement, matching the exact bore, stroke, force, G1/8 port, and mounting layout.
This SKU includes a built-in magnet (-S) for position sensing. On the original MAL body, which used threaded front and back covers, this magnet pairs with the older CS1-M / DS1-M switches. The modern MBL replacement features a riveted rolling-packed body and requires the current CMSG / DMSG / EMSG sensor family. Both generations rely on a fixed rubber bumper for end-of-stroke damping rather than an adjustable air cushion.

| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X145SU 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 MBL20X145SU 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 MAL20X145SU Is Used
PCB Depaneling Router
Provides 157N push at 0.5 MPa to drive a cutting head through populated circuit boards, relying on the 145mm stroke to clear fixture heights.
Microplate Stack Separator
Actuates a narrow gripper arm to lift and separate 96-well microplates, using the compact 20mm body to fit between tightly spaced lab automation lanes.
Small Bag Flap Folder
Extends 145mm to fold over the top flaps of small pouch packaging on a continuous conveyor before heat sealing.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X145SU with MBL20X145SU
To replace the MAL20X145SU, order the MBL20X145SU and transfer your existing PT-threaded piping to the G1/8 port. Because this SKU carries the -S magnet, you must also upgrade your CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG series to fit the MBL body. If your application needs adjustable end-cushioning rather than a fixed rubber bumper, step up to the current MBLC option.
For sizing flexibility, stepping down to a 20mm bore is already the smallest available option in this series. If you need more force, the next size up is the 25mm bore, which provides 245N push at 0.5 MPa. Note that a plain cylinder does not hold a load when air is lost; the rod drifts. For position holding, add an external rod lock or a pilot-operated check valve. At 145mm stroke, the 8mm rod has low side-load tolerance, so keep the load guided or use a pivot mounting.
Upgrade checklist
- ✓ Order the MBL20X145SU (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 MBL20X145SU instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X145SU FAQ
Yes, the MAL20X145SU is discontinued. The exact drop-in replacement is the MBL20X145SU, which offers the same 20mm bore, 145mm stroke, G1/8 port, and U flat-end cover. You simply order the MBL equivalent.
At 0.5 MPa, the 20mm bore provides 157N push and 132N pull force, 220N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa. The -S magnet on this MAL works with CS1-M / DS1-M switches, but the MBL replacement requires CMSG / DMSG / EMSG sensors.
