This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X135SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X135SCM 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 MAL20X135SCM
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X135SCM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 135mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X135SCM, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X135SCM
The AirTAC MAL20X135SCM is a discontinued compact double-acting aluminum mini round cylinder. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL20X135SCM, offering identical bore, stroke, force, G1/8 port, and CM round-end back cover for a seamless swap.
This legacy unit features a built-in magnet (-S) for position sensing, originally designed for CS1-M or DS1-M switches. When upgrading to the MBL20X135SCM, you must update to the current CMSG, DMSG, or EMSG sensor family. The older MAL relied on threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body for enhanced structural integrity. Inside, a heterogeneous two-way seal retains grease, and the 8 mm carbon-steel rod features 20 um hard-chrome plating to resist wear.

| 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 |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X135SCM 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 MBL20X135SCM 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 MAL20X135SCM Is Used
PCB Drill Spindle Guard
Powers a compact pivot gate guarding a PCB drilling spindle, using the 157 N push force to move the 135 mm stroke out of the way for tool changes.
IC Handler Ejector
Cycles a 135 mm stroke to push tested integrated circuits out of a test socket, where the CM round-end allows slight self-alignment during retraction.
Carton Flap Folder
Actuates a small mechanical flap-folder on a packaging line, relying on the -S magnet and a CS1-M switch to confirm the folding arm fully retracted.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X135SCM with MBL20X135SCM
To replace the MAL20X135SCM, order the MBL20X135SCM and verify your 8 mm rod-end thread (M8x1.25) and PT port threading. If your application requires less force, stepping down is not an option below 20 mm; stepping up to the 25 mm bore yields 245 N of push at 0.5 MPa. The CM round-end back cover accommodates arcing or pivoting loads, which is critical for this 135 mm stroke to prevent rod bending.
Note that this cylinder relies on a fixed rubber bumper, not an adjustable cushion; if end-of-stroke impact is an issue, specify the MBLC variant on the current line. Furthermore, the -S magnet on the MAL works with CS1-M / DS1-M switches, but the MBL replacement requires CMSG / DMSG / EMSG sensors. A plain cylinder does not hold its load when air is lost, so use an external rod lock for vertical safety.
Upgrade checklist
- ✓ Order the MBL20X135SCM (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 MBL20X135SCM instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X135SCM FAQ
Yes, the MAL20X135SCM is discontinued. The exact drop-in replacement is the MBL20X135SCM, which matches the 20 mm bore, 135 mm stroke, force, G1/8 port, and CM round-end mounting. You only need to update your position sensors, as the MBL uses CMSG / DMSG / EMSG switches instead of the older CS1-M / DS1-M.
The 20 mm bore provides a push force of 157 N and a pull force of 132 N at 0.5 MPa. At 0.7 MPa, the push force is 220 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
