This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X300SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X300SCM 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 B01-MAL Special Purpose Cylinder B01-MAL20X300SCM
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 300mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X300SCM, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCM
The AirTAC B01-MAL20X300SCM is a discontinued double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated, customer-specified variant of the base MAL20X300SCM, meaning it shares the exact same 20 mm bore, 300 mm stroke, and physical specs. AirTAC replaced the entire MAL line with the MBL series, making MBL20X300SCM the exact drop-in replacement. It delivers 157 N of push force at 0.5 MPa, utilizing a G1/8 port and an Ø8 mm carbon-steel rod with 20 um hard-chrome plating.
This legacy model features a fixed rubber bumper and a heterogeneous two-way seal that retains grease. The original MAL body used threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Because this SKU includes the -S magnet, it was designed to work with older CS1-M / DS1-M switches; upgrading to the MBL means the sensor family changes to CMSG / DMSG / EMSG.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X300SCM 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 B01-MBL20X300SCM 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 B01-MAL Special Purpose Cylinder B01-MAL20X300SCM Is Used
PCB Conveyor Gate
Lifts a hinged gate on an electronics assembly line to pass taller components, using the 300 mm stroke to clear the belt while the compact 20 mm bore saves space.
Carton Flap Folder
Extends 300 mm to fold the minor flaps of small corrugated boxes on a packaging machine, where the 157 N push force at 0.5 MPa is sufficient for light cardboard.
Lab Tube Ejector
Pushes a rack of test tubes out of a centrifuge loading bay; the CM round-end back cover allows slight angular self-alignment during the long 300 mm ejection.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCM with B01-MBL20X300SCM
To replace this discontinued cylinder, order the MBL20X300SCM. It matches the 20 mm bore, 300 mm stroke, G1/8 port, PT thread, and CM round-end back cover exactly. The -S magnet configuration carries over, but you must update your sensors from the legacy CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches. If your application requires an adjustable air cushion rather than the fixed rubber bumper, step up to the MBLC20X300 variant on the current line.
For sizing flexibility, stepping down to a 12 mm bore (if it existed) would lack force, but the next standard size up is the 25 mm bore, which yields 245 N push at 0.5 MPa for heavier loads. Conversely, if you need less force, the 20 mm bore is the smallest in this mini series, providing 157 N push and 132 N pull at 0.5 MPa. Because this is a 300 mm stroke on an 8 mm rod, side-load tolerance is very low; an external guide rail is required to prevent rod bending. Additionally, the bumper softens end-of-stroke impact but does not lock the rod—air loss will cause drift, so add a pilot-operated check valve for position holding.
Upgrade checklist
- ✓ Order the B01-MBL20X300SCM (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 B01-MBL20X300SCM instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X300SCM FAQ
Yes, the B01-MAL20X300SCM is discontinued. The exact drop-in replacement is the MBL20X300SCM, which shares the same 20 mm bore, 300 mm stroke, G1/8 port, and CM round-end cover. The "B01-" prefix simply designated an application-specific build of the base MAL cylinder. The modern MBL uses a riveted body instead of threaded covers, and if you use the -S magnet, you must switch from CS1-M / DS1-M sensors to CMSG / DMSG / EMSG switches.
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 increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s with a fixed rubber bumper for end-of-stroke damping.
