This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X100CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X100CA 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-MAL20X100CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL20X100CA 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 drop-in replacement is the B01-MBL20X100CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X100CA
The AirTAC B01-MAL20X100CA is a discontinued double-acting aluminum mini round cylinder. The leading B01- prefix marks this as an application-dedicated, customer-specified variant of the base MAL20X100CA, meaning it is mechanically identical to the standard unit. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. AirTAC replaced the entire MAL series with the MBL line, making the MBL20X100CA the exact drop-in replacement. It shares the same 20 mm bore, 100 mm stroke, G1/8 port, and CA pivot mounting.
The original MAL body used threaded front and back covers, whereas the current MBL features a riveted rolling-packed body for equally robust performance. This specific SKU lacks a magnet, so it cannot accept a position sensor. It relies on a fixed rubber bumper for end-of-stroke damping, not an adjustable air cushion. For applications requiring precise stopping, the current MBLC variant offers adjustable cushioning.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL20X100CA 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-MBL20X100CA 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-MAL20X100CA Is Used
PCB Depaneling Router
Actuates a routing blade guard on a PCB depaneling machine, where the 157 N push force at 0.5 MPa is sufficient for the guard motion and the CA pivot absorbs minor chassis deflection.
Semiconductor Test Socket
Drives the clamping lid of an automated IC test socket, using the 100 mm stroke to clear the handler pick-and-place head before lowering to test position.
Carton Flap Folder
Folds minor flaps on a small packaging line carton erector, where the compact 20 mm bore fits within tight side frames and the fixed rubber bumper prevents hard metal-to-metal impacts.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL20X100CA with B01-MBL20X100CA
To replace the B01-MAL20X100CA, order the MBL20X100CA. Confirm your 100 mm stroke, G1/8 port, PT thread, and CA pivot back cover. The CA clevis allows the cylinder to swing on a pin, which is essential for accommodating arcing rod movements. Because this SKU has no magnet, it cannot support a sensor; if you ever need position detection, you must upgrade to an MBL20X100S model and switch to the modern CMSG, DMSG, or EMSG switches.
When sizing, consider stepping down to a 12 mm bore for lighter loads or up to a 25 mm bore for more force. The 25 mm bore provides 245 N of push force at 0.5 MPa compared to this 20 mm bore's 157 N. Note that a plain MAL or MBL cylinder does not hold its position when air pressure is lost; the rod will drift. Use an external rod lock or pilot-operated check valve if you need to hold a vertical load.
Upgrade checklist
- ✓ Order the B01-MBL20X100CA (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-MBL20X100CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL20X100CA FAQ
Yes, the B01-MAL20X100CA is discontinued. The exact drop-in replacement is the MBL20X100CA, which shares the same 20 mm bore, 100 mm stroke, G1/8 port, and CA pivot back cover. The B01- prefix simply designated an application-specific build of the standard MAL20X100CA, so the MBL replacement functions identically.
At 0.5 MPa, the 20 mm bore provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. This specific CA pivot model has no magnet, so it cannot use a position sensor.
