This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X150SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X150SCA 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-MAL20X150SCA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X150SCA 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-MBL20X150SCA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X150SCA
The AirTAC B01-MAL20X150SCA 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 MAL20X150SCA, meaning it is mechanically identical to the standard model. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. AirTAC has ended this line, so the exact drop-in replacement is the MBL20X150SCA, matching the 20 mm bore, 150 mm stroke, G1/8 port, and CA pivot mounting.
This legacy unit features a threaded front and back cover assembly, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Because this SKU includes the -S magnet, it was designed to work with the older CS1-M and DS1-M reed switches; upgrading to the MBL means transitioning to the current CMSG, DMSG, or EMSG sensor families. The piston relies on a heterogeneous two-way seal that retains grease, and the Ø8 mm carbon-steel rod has 20 um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X150SCA 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-MBL20X150SCA 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-MAL20X150SCA Is Used
PCB Depaneling Router
Pushes a linear guide carriage on a printed circuit board depaneling machine, where 157 N of push force at 0.5 MPa is sufficient to separate routed panels without stressing the substrate.
Connector Insertion Arm
Cycles a low-inertia arm to press pin headers into sockets on an electronics assembly line, relying on the CA pivot to self-align during the 150 mm travel.
Carton Flap Folder
Folds minor flaps on small pharmaceutical cartons, using the compact 20 mm aluminum body to fit within tight packaging machine guarding.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X150SCA with B01-MBL20X150SCA
To replace this discontinued cylinder, order the MBL20X150SCA. Confirm your 150 mm stroke, G1/8 port, and PT thread form. The CA back cover provides a pivot clevis that swings on a pin to absorb arcing loads—keep this mounting accessory. Because this SKU has the -S magnet, note that your existing CS1-M or DS1-M sensors will not fit the MBL; you must upgrade to CMSG, DMSG, or EMSG switches.
For sizing flexibility, stepping down to a 32 mm bore is not applicable here, but if you need less force you could drop to a smaller bore (if available in your series) or step up to the 25 mm bore which provides 245 N push at 0.5 MPa. At 150 mm of travel, the fixed rubber bumper sufficiently softens end-of-stroke impacts, but if you need adjustable cushioning you must look at the MBLC variant on the current line. Remember that a plain cylinder does not hold its position when air is lost; the rod will drift. Use an external rod lock or pilot-operated check valve for load holding.
Upgrade checklist
- ✓ Order the B01-MBL20X150SCA (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-MBL20X150SCA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X150SCA FAQ
Yes, the B01-MAL20X150SCA (an application-dedicated variant of the MAL20X150SCA) is discontinued. The exact drop-in replacement is the MBL20X150SCA. It matches the 20 mm bore, 150 mm stroke, G1/8 port, CA pivot back cover, and -S magnet. The main change is that the MBL uses a riveted rolling-packed body instead of threaded covers, and it requires CMSG, DMSG, or EMSG sensors instead of the older CS1-M or DS1-M switches.
The 20 mm bore delivers 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. Operating pressure ranges from 0.1-1.0 MPa, and the cylinder speed ranges from 30-800 mm/s.
