This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL20X70 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL20X70 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-MAL20X70
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X70 is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 70mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL20X70, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X70
The AirTAC B05-MAL20X70 is a discontinued compact double-acting aluminum mini round cylinder engineered for manipulator and pick-and-place robot arms. The leading "B05-" prefix marks this as AirTAC's robot-dedicated variant, mechanically identical to the standard MAL20X70. 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 SKU lacks an -S magnet, it cannot accept a position sensor.
AirTAC replaced the entire MAL line with the MBL series, making the MBL20X70 the exact drop-in replacement. It matches the 70 mm stroke, output force, G1/8 port, and mounting dimensions. The legacy MAL uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body. The MAL relies on a fixed rubber bumper for end-of-stroke deceleration; if your robotic handling requires adjustable air cushioning, you must step up to the current MBLC variant. The piston employs a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide to support high-speed cycling.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL20X70 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-MAL20X70 Is Used
Pick-and-Place End Effector
Actuates the gripper jaw on a Cartesian robot arm, utilizing the 157 N push force at 0.5 MPa to securely clamp small electronic components during PCB transfer.
Manipulator Part Diversion
Drives a short-stroke pusher on a packaging manipulator to deflect lightweight plastic bottles from a main conveyor belt into a secondary labeling lane.
Semiconductor Wafer Sorting
Provides the vertical up-down motion for a suction-cpet head in a wafer handling station, cycling rapidly within the 30-800 mm/s speed range.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X70 with B05-MBL20X70
To replace the discontinued B05-MAL20X70, order the MBL20X70. Confirm your 20 mm bore, 70 mm stroke, G1/8 port, and default PT tapered thread. This SKU has no -S magnet, so it cannot support a CS1-M or DS1-M sensor; if your pick-and-place sequence requires end-of-stroke detection, order the MBL20X70S and migrate to the current CMSG, DMSG, or EMSG switch family. The fixed rubber bumper softens impact but is not an adjustable cushion—choose the MBLC20X70 if your robotic payload needs precise end-cushioning. A plain cylinder does not hold position when air pressure drops; add an external rod lock or pilot-operated check valve to prevent vertical payload drift.
For sizing flexibility, stepping down to the 16 mm bore is not an option in this mini series, but stepping up to the 25 mm bore yields 245 N of push force at 0.5 MPa if your end-effector payload increases. The 8 mm rod offers low side-load tolerance; even at 70 mm stroke, ensure your manipulator joint provides rigid alignment or use an external guide to prevent rod bending.
Upgrade checklist
- ✓ Order the B05-MBL20X70 (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-MBL20X70 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X70 FAQ
Yes, the B05-MAL20X70 is discontinued. The exact drop-in replacement is the MBL20X70, which matches the 20 mm bore, 70 mm stroke, 157 N push force, and G1/8 port. The "B05-" prefix simply designated the robot and manipulator pick-and-place application variant; mechanically, the MBL20X70 is identical. You can install the MBL20X70 directly into your existing fixture.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; if detection is needed, order the MBL20X70S and use CMSG, DMSG, or EMSG switches.
