This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X50CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X50CA 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-MAL20X50CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X50CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 50mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X50CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X50CA
The AirTAC B01-MAL20X50CA 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 MAL20X50CA, meaning it is mechanically identical to the standard model but grouped for specific customer builds. It delivers 157 N of push force at 0.5 MPa using an 8 mm carbon-steel rod with 20 um hard chrome plating. AirTAC replaced the MAL line with the MBL series, making the MBL20X50CA the exact drop-in replacement—matching the 20 mm bore, 50 mm stroke, G1/8 port, and CA pivot clevis.
The legacy MAL body uses threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for equally robust performance. This SKU lacks a built-in magnet (-S), so it cannot accept a position sensor. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable air cushion; if your application requires shock tuning, the current-line MBLC provides that feature. The piston utilizes a heterogeneous two-way seal that retains grease, working alongside a self-lubricating front-cover bearing guide to reduce friction.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X50CA 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-MBL20X50CA 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-MAL20X50CA Is Used
PCB Depaneling Router Gate
Actuates a small safety gate on a PCB depaneling machine, where the 157 N push force at 0.5 MPa easily moves the lightweight aluminum door and the CA pivot absorbs slight misalignment.
Socket Tester Clamp
Provides 132 N of pull force at 0.5 MPa to retract a small testing probe in an IC socket validation jig, fitting neatly into the tight 20 mm bore envelope.
Pharma Carton Flap Folder
Tucks the minor side flaps of small pharmaceutical cartons on a packaging line, utilizing the 50 mm stroke and fixed rubber bumper to prevent denting the lightweight paperboard.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X50CA with B01-MBL20X50CA
To replace this discontinued cylinder, order the MBL20X50CA. It drops directly into your existing setup with the same 20 mm bore, 50 mm stroke, PT tapered port thread, and CA pivot back cover. Because this specific SKU lacks the -S magnet, you cannot mount a position sensor on it; if you need end-of-stroke detection, step up to an MBL20X50SCA and note that the modern MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M / DS1-M family. The fixed rubber bumper softens impact but does not lock the rod—air loss will cause drift, so add an external rod lock for vertical loads.
When sizing, verify if 157 N push at 0.5 MPa is sufficient for your pivoting load. If you need less force, there is no smaller standard MAL bore, so you must reduce air pressure. If you need more power, step up to the 25 mm bore, which provides 245 N of push force at 0.5 MPa. The CA clevis back cover is essential here, as it allows the cylinder to swing on a pin and accommodate arcing loads without binding the 8 mm rod.
Upgrade checklist
- ✓ Order the B01-MBL20X50CA (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-MBL20X50CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X50CA FAQ
Yes, the AirTAC B01-MAL20X50CA is discontinued. The exact drop-in replacement is the MBL20X50CA, which shares the same 20 mm bore, 50 mm stroke, G1/8 port, and CA pivot mounting. The "B01-" prefix simply marked this as an application-dedicated variant of the base MAL20X50CA, so the MBL replacement matches all physical specs perfectly.
At 0.5 MPa, this 20 mm bore cylinder outputs 157 N push and 132 N pull. At 0.7 MPa, the push force is 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. It cannot hold its position when air is lost—the fixed rubber bumper only softens the end of stroke and does not function as a lock.
