This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X550-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X550-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 MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-S-CM
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 550mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X550-S-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-S-CM
The AirTAC MAL32X550-S-CM is a discontinued double-acting aluminum mini round cylinder with a 32 mm bore and a 550 mm stroke. Because the stroke exceeds the 500 mm standard limit, this is a made-to-order unit delivering 402 N of push force at 0.5 MPa. AirTAC replaced the MAL line with the MBL series, making the MBL32X550-S-CM the exact drop-in replacement. It matches the original bore, stroke, output force, G1/8 port, and mounting hardware perfectly.
This SKU includes a built-in magnet (-S) for position detection and a CM round-end back cover. The legacy MAL utilizes a threaded front and back cover assembly, whereas the modern MBL features a riveted rolling-packed body. If you relied on the older CS1-M or DS1-M reed switches on this MAL, you must upgrade to the current CMSG, DMSG, or EMSG sensor family when migrating to the MBL. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has a 20 µm hard-chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X550-S-CM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-S-CM Is Used
PCB Conveyor Divert
Pushes populated PCB panels laterally across a 500 mm transfer belt, utilizing the 402 N force to overcome guide friction without damaging delicate solder joints.
Lathe Tailstock Actuation
Advances a live center over a 550 mm travel to support long shafts, where the CM round-end back cover accommodates minor angular misalignment during chuck alignment.
Carton Push-off Arm
Stages corrugated cartons out of a vertical magazine, relying on the 346 N retract pull to reset the 550 mm extended arm against the weight of the packaging mechanism.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-S-CM with MBL32X550-S-CM
To replace the MAL32X550-S-CM, order the MBL32X550-S-CM. Confirm the 32 mm bore, 550 mm non-standard stroke, PT thread, and the CM round-end back cover are retained. Because this SKU has the -S magnet, remember that your existing CS1-M / DS1-M switches will not fit the MBL body; you must migrate to CMSG / DMSG / EMSG sensors. The MAL uses a fixed rubber bumper for end-of-stroke damping; if your application requires adjustable air cushioning to prevent shock at high speeds, step up to the MBLC variant on the current line.
When sizing, verify if 402 N push at 0.5 MPa is sufficient. Stepping down to a 25 mm bore drops the force to 245 N, while stepping up to a 40 mm bore increases it to 628 N. At 550 mm, the 12 mm rod is highly susceptible to bending under lateral stress; you must use an external guide rail or a pivot joint to prevent side-load damage. Additionally, a plain cylinder does not hold its load if air pressure drops—the rod will drift. Install an external rod lock or pilot-operated check valve if falling loads pose a safety hazard.
Upgrade checklist
- ✓ Order the MBL32X550-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 MBL32X550-S-CM instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-S-CM FAQ
Yes, the MAL32X550-S-CM is discontinued. The exact drop-in replacement is the AirTAC MBL32X550-S-CM, which provides identical bore, 550 mm stroke, force, G1/8 port, and CM round-end mounting. The MBL upgrades the body to a riveted rolling-packed design and requires CMSG / DMSG / EMSG sensors to replace the older CS1-M / DS1-M switches.
At 0.5 MPa operating pressure, the 32 mm bore generates 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. Note that this 550 mm stroke is a non-standard, made-to-order length exceeding the 500 mm standard maximum.
