This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X250SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X250SCM 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-MAL20X250SCM
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X250SCM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 250mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X250SCM, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X250SCM
The AirTAC B01-MAL20X250SCM is a discontinued compact double-acting aluminum mini round cylinder with a 20 mm bore and 250 mm stroke. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base MAL20X250SCM, meaning it is mechanically identical to the standard model but grouped for a specific customer build. Delivering 157 N of push force at 0.5 MPa, it is engineered for tight spaces. AirTAC replaced the MAL series with the MBL line, making the MBL20X250SCM the exact drop-in replacement sharing the same force, G1/8 port, and mounting.
This SKU includes a built-in magnet (-S) for position detection and a CM round-end back cover. The original MAL body uses threaded front and back covers, whereas the newer MBL features a riveted rolling-packed body. Internally, a heterogeneous two-way seal retains grease, and the 8 mm carbon-steel rod has 20 um hard-chrome plating running through a self-lubricating front-cover bearing guide.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X250SCM 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-MBL20X250SCM 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-MAL20X250SCM Is Used
PCB Router Gate
Actuates a routing gate on a printed circuit board depaneling machine, using the 250 mm stroke to clear the work area while the 157 N push force handles the lightweight aluminum jig.
Lab Tube Ejector
Extends to push processed assay tubes out of a centrifuge carousel in diagnostic equipment, where the compact 20 mm bore fits between densely packed spindles.
Carton Flap Folder
Deploys a folding arm on a small packaging line to tuck minor flaps on pharmaceutical cartons, relying on the CM round-end to accommodate slight misalignment during the arc motion.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X250SCM with B01-MBL20X250SCM
To replace this discontinued cylinder, order the MBL20X250SCM. Confirm the 20 mm bore, 250 mm stroke, PT thread, and CM round-end back cover are retained. Because this SKU has the -S magnet, note the sensor family changes: the older MAL works with CS1-M / DS1-M switches, while the MBL requires CMSG / DMSG / EMSG sensors. If you need to step up force, the 25 mm bore offers 245 N push at 0.5 MPa; stepping down is not an option as 20 mm is the smallest available. At 250 mm stroke, the 8 mm rod has low side-load tolerance, so use an external guide or pivot to prevent rod bending. The fixed rubber bumper softens end-of-stroke impact but does not hold position; for a locked load, add an external rod lock. If you need adjustable cushioning, specify the MBLC on the current line.
Upgrade checklist
- ✓ Order the B01-MBL20X250SCM (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-MBL20X250SCM instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X250SCM FAQ
Yes, the B01-MAL20X250SCM (an application-dedicated variant of the base MAL20X250SCM) is discontinued. The exact drop-in replacement is the MBL20X250SCM, which matches the 20 mm bore, 250 mm stroke, G1/8 port, and CM round-end mounting. The MBL uses a riveted body instead of threaded covers, and if your SKU has a magnet, you must upgrade from CS1-M / DS1-M switches to CMSG / DMSG / EMSG sensors.
At 0.5 MPa, the 20 mm bore provides 157 N push and 132 N pull force; at 0.7 MPa it provides 220 N push, with a theoretical maximum of 32 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion; if adjustable air cushioning is required, specify the MBLC variant on the current MBL line.
