This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X40CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X40CM 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-MAL20X40CM
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X40CM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 40mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X40CM, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X40CM
The AirTAC B01-MAL20X40CM is a discontinued, compact double-acting aluminum mini round cylinder. The "B01-" prefix designates this as an application-dedicated, customer-specified variant of the standard MAL20X40CM, meaning it shares the exact same mechanical specifications—delivering 157 N of push force and 132 N of pull force at 0.5 MPa. As a legacy unit, its exact drop-in replacement is the MBL20X40CM, which matches the 20 mm bore, 40 mm stroke, G1/8 port, and CM round-end back cover perfectly.
This 20 mm bore unit features an Ø8 mm carbon-steel rod with 20 um hard-chrome plating, guided by a self-lubricating front-cover bearing. The original MAL body utilizes threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for equally robust performance. This SKU lacks a built-in magnet, so it cannot support position sensors. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X40CM 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 | — |

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X40CM Is Used
PCB Depaneling Router
Routes small printed circuit boards using 157 N of push force at 0.5 MPa, fitting easily into tight electronics assembly fixtures.
Pharma Vial Sorting Gate
Actuates a compact diverter gate for 10 ml vials on a high-speed packaging line, utilizing the 40 mm stroke and CM round-end cover for tight clearances.
Micro-Clip Insertion
Pushes small spring clips into connector housings, relying on the self-lubricating front-cover bearing to maintain precise rod alignment over thousands of cycles.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X40CM with B01-MBL20X40CM
To replace the B01-MAL20X40CM, order the MBL20X40CM. It is a true drop-in upgrade: you keep the identical 20 mm bore, 40 mm stroke, PT thread form, G1/8 port, and CM round-end back cover. Because this specific legacy unit lacks the -S magnet code, it cannot accept a position sensor. If your upgrade path requires rod-position detection, you must order the MBL20X40CMS and migrate to the current CMSG, DMSG, or EMSG switch family, as the older CS1-M and DS1-M sensors are obsolete.
When sizing this cylinder, consider stepping up or down based on your force requirements. If 157 N of push at 0.5 MPa is too much, step down to a 16 mm bore (confirm the exact force from the datasheet). If you need more power, step up to the 32 mm bore, which provides 402 N of push at 0.5 MPa. Note that the fixed rubber bumper softens end-of-stroke impacts but does not lock the rod; if you need to hold a load vertically without air, add an external rod lock. For applications requiring adjustable end-cushioning, specify the MBLC variant on the current line.
Upgrade checklist
- ✓ Order the B01-MBL20X40CM (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-MBL20X40CM instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X40CM FAQ
Yes, the B01-MAL20X40CM is discontinued. The "B01-" prefix simply marks it as an application-dedicated variant of the base MAL20X40CM. The exact drop-in replacement is the MBL20X40CM, which offers the same 20 mm bore, 40 mm stroke, G1/8 port, and CM round-end cover. The main physical change is that the MBL uses a riveted rolling-packed body instead of the MAL's threaded covers.
At 0.5 MPa, the 20 mm bore provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. This unit uses a fixed rubber bumper, so if your application requires adjustable air cushioning, you should look at the MBLC20X40CM on the current line.
