This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X150CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X150CA 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-MAL20X150CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X150CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X150CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X150CA
The AirTAC B01-MAL20X150CA is a discontinued compact double-acting aluminum mini round cylinder. The leading "B01-" prefix designates this as an application-dedicated (customer-specified) variant of the base MAL20X150CA, meaning it is mechanically identical to the standard model. Delivering 157 N of push force at 0.5 MPa, it features a 20 mm bore, 150 mm stroke, and a G1/8 port. AirTAC has replaced this legacy series with the MBL20X150CA, a drop-in upgrade that matches the exact bore, stroke, output force, port size, and CA mounting interface.
Mechanically, the legacy MAL body relies on threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body for secure assembly. This SKU lacks a built-in magnet (-S), so it cannot support position sensing without physical modification. Internally, a heterogeneous two-way seal retains grease, and the carbon-steel rod features 20 um hard-chrome plating to resist wear. The end of stroke is controlled by a fixed rubber bumper, not an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X150CA 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-MBL20X150CA 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-MAL20X150CA Is Used
PCB routing head pivot
Drives a light depaneling blade through a 150 mm arc on an electronics assembly line, using the CA clevis to accommodate the router head swing.
Tote box push-off
Ejects small packaged totes from a conveyor at 157 N push force, relying on the compact 20 mm body to fit within tight conveyor framework.
Lab vial tray transfer
Shifts lightweight sample trays between testing stations, where the self-lubricating front-cover bearing guide ensures smooth operation in cleanroom-adjacent environments.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X150CA with B01-MBL20X150CA
To replace the B01-MAL20X150CA, order the MBL20X150CA. Confirm your 20 mm bore, 150 mm stroke, G1/8 PT port, and the CA pivot back cover are retained in the new order. Because this SKU has no -S code, it cannot accept a position sensor; if you need rod detection on the new MBL, add the -S option and note that the sensor family changes from the old CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches. The fixed rubber bumper cannot be adjusted; if your application requires end-of-stroke deceleration, step up to the MBLC variant which offers adjustable air cushions.
When sizing, stepping down to a 12 mm bore drops the 0.5 MPa push force to roughly 113 N, while stepping up to a 25 mm bore increases it to 245 N. With a 150 mm stroke, the 8 mm rod has low side-load tolerance; the CA clevis back cover is essential here as it pivots on a pin to absorb arcing motion. A plain bumper does not hold position if air pressure drops, so fit an external rod lock for vertical loads.
Upgrade checklist
- ✓ Order the B01-MBL20X150CA (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-MBL20X150CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X150CA FAQ
Yes, the B01-MAL20X150CA is discontinued. The exact drop-in replacement is the AirTAC MBL20X150CA, which offers the same 20 mm bore, 150 mm stroke, 157 N push force at 0.5 MPa, G1/8 port, and CA pivot mounting. The "B01-" prefix simply marked this as an application-dedicated variant; the MBL upgrade handles the exact same physical specs.
At 0.5 MPa it provides 157 N push and 132 N pull force. At 0.7 MPa the push force is 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. End-of-stroke cushioning is handled by a fixed rubber bumper; it is not adjustable. If adjustable air cushioning is required, you must use the current MBLC line.
