This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL20X100S, 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-MAL20X100S
The AirTAC B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100S is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 100mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL20X100S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100S
The AirTAC B05-MAL20X100S is a discontinued compact double-acting aluminum mini round cylinder. The B05- prefix marks this as a robot or manipulator pick-and-place dedicated variant, though mechanically it is identical to the base MAL20X100S. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. AirTAC replaced this legacy unit with the MBL20X100S, a direct alternative retaining the exact 20 mm bore, 100 mm stroke, G1/8 port, and mounting footprint.
Two engineering details distinguish this series. First, the original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for faster assembly. Second, this -S SKU includes a magnet for position sensing; the legacy MAL works with older CS1-M or DS1-M switches, but the MBL successor transitions to the current CMSG, DMSG, or EMSG sensor families. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a heterogeneous two-way seal that retains grease.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100S Is Used
Pick-and-Place Robot Arms
Drives the vertical Z-axis jaw on assembly manipulators, utilizing its 157 N push force to grip and lift small electronic components during PCB routing.
Semiconductor Wafer Handling
Actuates the extending probe arm in cleanroom sorting tools, where the lightweight aluminum body minimizes inertia on fast 100 mm strokes.
Packaging Line Diverters
Pushes lightweight cartons between adjacent packaging lanes, benefiting from the 30-800 mm/s speed range to maintain high throughput.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100S with B05-MBL20X100S
To replace the B05-MAL20X100S, order the MBL20X100S. Confirm your PT thread port, G1/8 fitting, and M8x1.25 rod-end threading. Because this unit has the -S magnet, plan to upgrade your CS1-M or DS1-M sensors to CMSG, DMSG, or EMSG switches to match the MBL body. If your manipulator requires adjustable end-cushioning instead of the standard fixed rubber bumper, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to a 16 mm bore is not an option in this family, but stepping up to the 25 mm bore yields 245 N of push force at 0.5 MPa if you need more clamping power. Note that a plain cylinder does not hold its position when air pressure drops; the bumper only softens impact. At 100 mm of stroke, side-load tolerance remains manageable, but always ensure the manipulator jaw guides absorb lateral forces to protect the 8 mm carbon-steel rod.
Upgrade checklist
- ✓ Order the B05-MBL20X100S (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-MBL20X100S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100S FAQ
Yes, the B05-MAL20X100S is discontinued. The direct replacement is the MBL20X100S, which matches the 20 mm bore, 100 mm stroke, G1/8 port, and mounting dimensions. The B05- prefix simply designated it for manipulator use, and the MBL replacement 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. The -S suffix denotes a built-in magnet for use with CS1-M or DS1-M switches; note that the MBL20X100S replacement requires newer CMSG, DMSG, or EMSG sensors.
