This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X450-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X450-S-CM 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 MAL20X450-S-CM
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X450-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 450mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X450-S-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X450-S-CM
The AirTAC MAL20X450-S-CM is a discontinued double-acting aluminum mini round cylinder. It delivers 157 N push and 132 N pull at 0.5 MPa from a 20 mm bore. The exact drop-in replacement is the MBL20X450-S-CM, matching the 450 mm stroke, G1/8 port, 32 kgf max force, and CM round-end back cover.
This legacy unit features an 8 mm carbon-steel rod with 20 um hard chrome plating, guided by a self-lubricating front-cover bearing. The original MAL body uses threaded front and back covers, whereas the MBL upgrade uses a riveted rolling-packed body for equal strength. Because this SKU includes the -S magnet, it originally paired with CS1-M / DS1-M switches; the MBL replacement requires the current CMSG / DMSG / EMSG sensor family. End-of-stroke energy relies on a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X450-S-CM 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 MBL20X450-S-CM 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X450-S-CM Is Used
PCB Depaneling Router
Drives a routing blade across 400 mm of travel to singulate populated FR4 circuit boards, using the 132 N pull force to retract the tool safely out of the cutting zone.
Bottle Diverter Arm
Swings a lightweight gate via the CM round-end to shift empty PET bottles between dual packaging lanes, relying on the 157 N push force at 0.5 MPa.
Carton Pusher Mechanism
Transfers small corrugated cartons into a side taping station, where the fixed rubber bumper absorbs the 450 mm stroke impact without crushing the fiberboard.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X450-S-CM with MBL20X450-S-CM
To replace the MAL20X450-S-CM, order the MBL20X450-S-CM. Confirm your 8 mm rod-end thread (M8x1.25) and the default PT port. The CM round-end back cover accommodates arcing or pivoting loads, which is critical given the 450 mm stroke. If your application needs adjustable end-cushioning to absorb kinetic energy, step up to the MBLC variant on the current line, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, while stepping up is not possible as 20 mm is the smallest available MAL bore. A plain MBL does not hold a load when air is lost; the rod drifts, so fit an external rod lock or pilot-operated check valve if position holding is required. At 450 mm, the small 8 mm rod has low side-load tolerance; pair the CM cover with an external guide or pivot bracket to prevent rod bending.
Upgrade checklist
- ✓ Order the MBL20X450-S-CM (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 MBL20X450-S-CM instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X450-S-CM FAQ
Yes, the MAL20X450-S-CM is discontinued. The exact drop-in replacement is the MBL20X450-S-CM, offering the same 20 mm bore, 450 mm stroke, 32 kgf max force, G1/8 port, and CM round-end. The -S magnet on the MBL uses the newer CMSG / DMSG / EMSG switches instead of the older CS1-M / DS1-M.
The 20 mm bore generates a push force of 157 N and a pull force of 132 N at 0.5 MPa. At 0.7 MPa, the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
