This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL20X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL20X75S 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 B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75S
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75S 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 B05-MBL20X75S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75S
The AirTAC B05-MAL20X75S is a discontinued compact double-acting aluminum mini round cylinder. The B05- prefix designates this as a robot and manipulator (pick-and-place) dedicated variant, though it is mechanically identical to the standard MAL20X75S. Delivering 157 N of push force at 0.5 MPa, it uses a G1/8 port and an 8 mm carbon-steel rod with 20 um hard-chrome plating. AirTAC replaced this legacy series with the MBL20X75S, a drop-in upgrade retaining the exact bore, stroke, force, and mounting interface.
The original MAL body used threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for faster assembly. This -S SKU includes a magnet for position sensing; on the MAL it pairs with older CS1-M or DS1-M switches, but the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families. The cylinder relies on a fixed rubber bumper and a heterogeneous two-way grease-retaining seal rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL20X75S 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 B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75S Is Used
Pick-and-Place Robot Arms
Drives the 75 mm extend and retract motion on lightweight manipulator grippers, utilizing the 157 N push force to transfer small electronic components between conveyor belts.
PCB Board Handling
Moves delicate printed circuit boards out of testing stations, where the compact 20 mm aluminum barrel fits neatly within dense robotic work cells.
Small Parts Ejection
Pushes lightweight plastic housings from molding machines into collection bins, relying on the self-lubricating front-cover bearing guide for smooth repetitive cycling.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75S with B05-MBL20X75S
To replace the B05-MAL20X75S, order the MBL20X75S. Confirm your 75 mm stroke, G1/8 port, and PT thread form. Because this SKU includes the -S magnet, you must upgrade your sensing setup: the legacy CS1-M and DS1-M switches will not fit the MBL, so migrate to CMSG, DMSG, or EMSG sensors. If your application requires an adjustable air cushion rather than the fixed rubber bumper, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to the 20 mm bore is the minimum available, so if you need less force you must switch platforms entirely. If you need more power, the next size up is the 32 mm bore, which provides 402 N of push force at 0.5 MPa. Note that a plain MAL or MBL cylinder does not hold its position when air pressure is lost; the rod will drift. For vertical pick-and-place loads, add an external rod lock or pilot-operated check valve.
Upgrade checklist
- ✓ Order the B05-MBL20X75S (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 B05-MBL20X75S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75S FAQ
Yes, the B05-MAL20X75S is discontinued. The exact drop-in replacement is the MBL20X75S, which matches the 20 mm bore, 75 mm stroke, G1/8 port, and force ratings. The B05- prefix simply marked it as a pick-and-place robot variant, and the MBL serves as the direct mechanical upgrade. If you use the -S magnet for sensing, you must switch from the old CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG family.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. It operates on filtered air between 0.1-1.0 MPa, runs at speeds of 30-800 mm/s, and uses a fixed rubber bumper rather than an adjustable cushion.
