This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL20X75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL20X75 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-MAL20X75
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75 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-MBL20X75, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75
The AirTAC B05-MAL20X75 is a discontinued compact double-acting aluminum mini round cylinder. The leading "B05-" prefix marks this as a robot or manipulator (pick-and-place) dedicated variant, though mechanically it is identical to the standard MAL20X75. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa, utilizing a G1/8 port and an 8 mm carbon-steel rod with 20 um hard-chrome plating. Because this unit lacks the -S magnet option, it cannot accept a position sensor.
AirTAC replaced the legacy MAL line with the MBL series, making the MBL20X75 the exact drop-in replacement. It matches the 75 mm stroke, output force, port size, and mounting footprint. The original MAL features threaded front and back covers, whereas the newer MBL uses a riveted rolling-packed body. Furthermore, the MAL relies on a fixed rubber bumper for end-of-stroke damping, whereas the current MBLC variant offers an adjustable air cushion if your manipulator requires softer deceleration.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL20X75 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 B05-MBL20X75 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 B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75 Is Used
Pick-and-Place Robot Arms
Drives the vertical Z-axis on Cartesian manipulators for transferring electronic components, utilizing the 75 mm stroke and 157 N push force for rapid, light-duty handling.
PCB Board Handling
Actuates small pusher fingers in surface mount technology lines to align or eject printed circuit boards without damaging delicate traces.
Small Part Ejection
Clears small plastic or stamped metal parts from pick-and-place end-effectors in high-speed packaging assembly cells.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75 with B05-MBL20X75
To replace this discontinued manipulator cylinder, order the MBL20X75. Confirm your manipulator's mounting accessory (LB foot, FA flange, or SDB pivot) and thread form (this unit uses default PT tapered) to ensure a seamless drop-in fit. Since this specific SKU lacks an -S magnet, it cannot support position sensing; if your pick-and-place routine requires end-of-stroke confirmation, step up to an MBL20X75S and note that the newer MBL platform uses CMSG, DMSG, or EMSG switches instead of the older CS1-M / DS1-M sensors.
For sizing flexibility, stepping down to a 16 mm bore is not an option in this mini round family. Stepping up to the 32 mm bore yields 402 N of push force at 0.5 MPa if your robotic gripper needs substantially more clamping power. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost; the fixed bumper softens impact but does not lock the rod, so add an external rod lock for vertical manipulator arms. The 8 mm rod handles high-speed cycling well, but side-load tolerance is low, so rely on the robot arm's own guidance system rather than the cylinder rod.
Upgrade checklist
- ✓ Order the B05-MBL20X75 (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-MBL20X75 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X75 FAQ
Yes, the B05-MAL20X75 is discontinued. The exact drop-in replacement is the MBL20X75, which shares the same 20 mm bore, 75 mm stroke, force, G1/8 port, and mounting dimensions. The "B05-" prefix simply designated it as a robot and manipulator dedicated variant; the replacement MBL20X75 functions identically.
At 0.5 MPa, it provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force is 220 N, with a theoretical maximum of 32 kgf at 1.0 MPa. Because this specific SKU does not have the -S magnet, it cannot accept CS1-M or DS1-M position sensors.
