This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL20X30, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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-MAL20X30
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X30 is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 30mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL20X30, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X30
The AirTAC B05-MAL20X30 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 it is mechanically identical to the base MAL20X30. It delivers 157 N of push force at 0.5 MPa using an 8 mm carbon-steel rod with 20 um hard chrome plating. Because this legacy series is end-of-life, you should order the direct replacement: the MBL20X30. It matches the 20 mm bore, 30 mm stroke, G1/8 port, and PT thread exactly.
The MBL upgrade transitions from the older MAL threaded front and back covers to a riveted rolling-packed body, maintaining the same physical ratings. This specific SKU lacks a magnet (-S), so it cannot accept a position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease, and end-of-stroke deceleration is handled strictly by a fixed rubber bumper, not an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL20X30 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-MAL20X30 Is Used
Pick-and-Place Robot Arms
Drives the short 30 mm vertical lift on assembly manipulators, providing 157 N of push at 0.5 MPa to raise light electronic components without overshoot.
PCB Board Handling
Actuates a small 20 mm bore ejection pin in tight semiconductor fixtures, fitting into 1/8 port restricted spaces where larger profile cylinders cannot fit.
Thermoformed Tray Sorting
Pushes thin plastic trays out of a stacking magazine using a rapid 30 mm stroke, relying on the self-lubricating bearing guide for millions of friction-free cycles.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X30 with B05-MBL20X30
To replace this discontinued manipulator cylinder, order the MBL20X30. Confirm your robot arm's mounting pitch matches the standard LB foot, FA flange, or SDB pivot brackets, and that your fittings match the G1/8 PT port. Since this SKU has no -S magnet, you cannot mount a sensor; if your pick-and-place routine requires end-of-stroke detection, step up to an MBL20X30S and upgrade to the current CMSG, DMSG, or EMSG switch family (the older CS1-M/DS1-M sensors are retired with the MAL line).
For sizing flexibility, stepping down is not an option as 20 mm is the smallest available bore. If the 157 N push at 0.5 MPa is insufficient for lifting your gripper payload, step up to the 25 mm bore, which provides 245 N of push force at 0.5 MPa. Note that the fixed rubber bumper softens impacts but does not lock the load; if air pressure drops, the rod will drift. For critical position holding, add an external rod lock.
Upgrade checklist
- ✓ Order the B05-MBL20X30 (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-MBL20X30 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X30 FAQ
Yes, the B05-MAL20X30 (the robot/manipulator dedicated variant of the MAL20X30) is discontinued. The direct replacement is the MBL20X30. It offers identical bore, stroke, output force, G1/8 port, and mounting compatibility. The primary upgrade is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
The 20 mm bore provides a push force of 157 N and a pull force of 132 N at 0.5 MPa, a push force of 220 N at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke damping, which is not an adjustable cushion or a lock. The cylinder will drift if air pressure is lost, so an external rod lock is required for fail-safe position holding.
