This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X80CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X80CA 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 B01-MAL Special Purpose Cylinder B01-MAL20X80CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X80CA is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 80mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X80CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X80CA
The AirTAC B01-MAL20X80CA is a discontinued compact double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated, customer-specified variant of the base MAL20X80CA, meaning it is mechanically identical to the standard catalog model. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa, utilizing an 8 mm carbon-steel rod with 20 um hard-chrome plating.
AirTAC replaced this legacy unit with the MBL20X80CA, a true drop-in replacement retaining the exact 20 mm bore, 80 mm stroke, G1/8 port, and CA pivot mounting. The original MAL body used threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body. This SKU lacks a built-in magnet, so it cannot accept position sensors without a physical modification.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X80CA 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 B01-MBL20X80CA 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 B01-MAL Special Purpose Cylinder B01-MAL20X80CA Is Used
PCB router gate
Pivots a small flap gate on a pick-and-place machine to route printed circuit boards, using the CA clevis to accommodate the swing arc.
Carton flap folder
Provides 157 N of push at 0.5 MPa to fold small corrugated box flaps in a packaging line, fitting easily into tight machine clearances.
Test tube ejector
Extends 80 mm to push capped sample tubes out of a centrifuge carousel, relying on the self-lubricating front-cover bearing for smooth cycling.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X80CA with B01-MBL20X80CA
To replace this discontinued cylinder, order the MBL20X80CA. Confirm your 80 mm stroke, G1/8 port, PT thread, and the CA pivot back cover, which swings on a pin to accommodate arcing loads. If you need to step down, the nearest smaller bore is 12 mm (confirm from datasheet for force); if you need more force, step up to the 25 mm bore, which provides 245 N push at 0.5 MPa. Because this 80 mm stroke is relatively short, side-load risk is minimal, but the 8 mm rod still demands careful alignment. The fixed rubber bumper softens end-of-stroke impacts but does not lock the rod; if air pressure drops, the load will drift. For end-of-stroke deceleration control, look at the current MBLC line which adds adjustable air cushions.
Upgrade checklist
- ✓ Order the B01-MBL20X80CA (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 B01-MBL20X80CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X80CA FAQ
Yes, the B01-MAL20X80CA is discontinued. The exact drop-in replacement is the MBL20X80CA. The "B01-" prefix simply denotes an application-dedicated build of the standard MAL20X80CA, so the MBL20X80CA matches your 20 mm bore, 80 mm stroke, G1/8 port, and CA pivot exactly.
At 0.5 MPa it pushes with 157 N and pulls with 132 N. At 0.7 MPa the push force is 220 N, and the maximum theoretical force is 32 kgf at 1.0 MPa. This specific SKU lacks the -S magnet, so it cannot use CS1-M or DS1-M sensors; if you need position detection, order the MBL20X80CAS, which uses the modern CMSG/DMSG/EMSG switches.
