This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X75SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X75SU 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-MAL20X75SU
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X75SU is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 75mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X75SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X75SU
The AirTAC B01-MAL20X75SU is a discontinued double-acting aluminum mini round cylinder. The leading "B01-" prefix designates an application-dedicated, customer-specified variant of the base MAL20X75SU, meaning it shares the exact same 20 mm bore, 75 mm stroke, and mechanical specs. As a 20 mm bore class actuator, it delivers 157 N of push force and 132 N of pull force at 0.5 MPa. AirTAC has replaced this legacy unit with the MBL20X75SU, a drop-in alternative retaining the same G1/8 port, M8x1.25 rod thread, and U flat-end rear cover.
This SKU includes a built-in magnet (-S) for position detection. On the legacy MAL body—which uses threaded front and back covers—the magnet pairs with older CS1-M or DS1-M reed switches. The modern MBL replacement features a riveted rolling-packed body and requires the current CMSG, DMSG, or EMSG sensor families. Inside, a heterogeneous two-way seal retains grease, and the carbon-steel rod has a 20 um hard-chrome plating to resist wear. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X75SU 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-MBL20X75SU 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-MAL20X75SU Is Used
PCB Test Handler
Provides 157 N of push force at 0.5 MPa to actuate test pins on a PCB handler, fitting easily into tight electronics assembly machinery.
Carton Label Applicator
Extends 75 mm to press an applicator pad against small packaging boxes, using the U flat-end cover for rigid, straight-line mounting.
Small Part Ejector
Ejects molded plastic parts from a die, relying on the 20 um hard-chrome plated rod to withstand repetitive cycling in a dry-air environment.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X75SU with B01-MBL20X75SU
To replace the B01-MAL20X75SU, order the MBL20X75SU. Verify your 75 mm stroke, G1/8 port, PT thread, and the rigid U flat-end back cover. Because this SKU has the -S magnet, remember that your existing CS1-M or DS1-M switches will not fit the MBL body; you must upgrade to CMSG, DMSG, or EMSG sensors. The fixed rubber bumper softens impact, but if your application requires adjustable end-cushioning, step up to the MBLC variant on the current line. A plain cylinder does not hold position if air pressure drops; install an external rod lock for safety-critical holding.
When sizing, the 20 mm bore provides 157 N push at 0.5 MPa. If you need less force, there is no smaller MAL size, so you must restrict the pressure. If you need more power, step up to the 25 mm bore, which yields 245 N of push force at 0.5 MPa. With a 75 mm stroke, side-load risk is moderate, but the small 8 mm rod means you should use an external guide for heavy or off-center loads.
Upgrade checklist
- ✓ Order the B01-MBL20X75SU (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-MBL20X75SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X75SU FAQ
Yes, the B01-MAL20X75SU is discontinued. The exact drop-in replacement is the MBL20X75SU, offering the same 20 mm bore, 75 mm stroke, G1/8 port, and U flat-end cover. The "B01-" prefix simply marked it as an application-dedicated variant; the MBL replaces it mechanically. Note that if your unit has a magnet, you must switch from the old CS1-M/DS1-M switches to the new CMSG/DMSG/EMSG sensors.
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. It uses a G1/8 port and an 8 mm rod with an M8x1.25 thread.
