This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X100-S-CA-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X100-S-CA-LB 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-CA-LB
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-CA-LB 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 MBL20X100-S-CA-LB, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-CA-LB
The AirTAC MAL20X100-S-CA-LB is a discontinued double-acting aluminum mini round cylinder. It delivers 157 N of push force at 0.5 MPa through an 8 mm carbon-steel rod with 20 um hard-chrome plating. The exact drop-in replacement is the MBL20X100-S-CA-LB, which matches the 20 mm bore, 100 mm stroke, G1/8 port, and LB foot mounting. The legacy MAL uses threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for equally robust performance.
This specific SKU includes a built-in magnet (-S) for position sensing. On the MAL, this magnet pairs with older CS1-M or DS1-M reed switches, but upgrading to the MBL requires the current CMSG, DMSG, or EMSG sensor family. The cylinder relies on a heterogeneous two-way seal that retains grease, and the front-cover bearing guide is self-lubricating for extended cycle life. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable air cushion.

Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |

Where the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-CA-LB Is Used
PCB Depaneling Ejector
Uses the 157 N push force at 0.5 MPa to eject cut circuit boards from a routing fixture without damaging delicate traces.
Pharmacy Pouch Indexing
The 100 mm stroke pushes small medical pouches into a sealing jaw, relying on the LB foot mount to keep the body rigid during rapid 30-800 mm/s cycling.
Microplate Shuttle Transfer
Moves assay plates between analytical stations, utilizing the -S magnet and CS1-M sensors to confirm plate handoff at the end of travel.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-CA-LB with MBL20X100-S-CA-LB
To replace the MAL20X100-S-CA-LB, order the MBL20X100-S-CA-LB. Confirm the 100 mm stroke, G1/8 port, PT thread form, CA pivot back cover, and LB foot mounting accessory are retained. Because this SKU has the -S magnet, plan to update your sensing to CMSG, DMSG, or EMSG switches, as the older CS1-M and DS1-M sensors will not fit the new body. If your application requires adjustable end-cushioning to prevent end-stroke knocking, step up to the MBLC variant on the current line, since the MAL only offers a fixed rubber bumper.
For sizing flexibility, stepping down to a 12 mm bore reduces your footprint but sacrifices thrust, while stepping up to the 25 mm bore yields 245 N of push force at 0.5 MPa. Keep in mind that a plain MAL or MBL does not hold its load if air pressure drops; the rod will drift. For vertical loads, add an external rod lock or pilot-operated check valve. Additionally, the 100 mm stroke on an 8 mm rod means side-load tolerance is low; use the CA pivot back cover to absorb arcing alignment discrepancies.
Upgrade checklist
- ✓ Order the MBL20X100-S-CA-LB (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 MBL20X100-S-CA-LB instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-CA-LB FAQ
Yes, the MAL20X100-S-CA-LB is discontinued. The exact drop-in replacement is the MBL20X100-S-CA-LB. It provides identical bore, stroke, output force, G1/8 port, and LB mounting. The main upgrade is the body construction: the MAL uses threaded covers while the MBL uses a riveted rolling-packed body. If you use the -S magnet for sensing, you must switch from the older CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG family.
The 20 mm bore provides a push force of 157 N and a pull force of 132 N at 0.5 MPa. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa operating pressure.
