About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X300CA
The AirTAC MBLC40X300CA is a double-acting aluminum mini cylinder featuring a 40mm bore and 300mm stroke, delivering 628N of push force at 0.5MPa. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor. The CA back cover provides a pivot clevis that swings on a pin, making it ideal for arcing or angular load paths.
Screw-adjustable pneumatic air cushions at both ends allow you to tune the end-of-stroke deceleration, absorbing kinetic energy to prevent end-cover impact on heavier or fast-moving loads. The riveted rolling-packed aluminum barrel keeps the body compact, while the Ø16mm carbon-steel rod features 20µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for extended service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X300CA Is Used
Pick-and-Place Gantries
Drives 300mm vertical lifts on electronic PCB assembly gantries, where the tunable air cushion ensures soft landing for delicate components despite the 628N force capacity.
Pallet Diverters
Actuates angular sorting arms on packaging conveyor lines, leveraging the CA pivot clevis to accommodate the swing arc while cushioning the rapid 40mm bore thrust.
Drawer Ejectors
Pushes loaded material drawers out of CNC machining centers, using the 300mm travel to fully clear the work zone before robotic extraction.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X300CA the Right Cylinder?
Choose this 40mm bore when you need 628N push at 0.5MPa; step down to the 32mm bore for 402N if moving lighter payloads, or step up to the 50mm bore for 981N when pushing heavier masses. Select the MBLC over the fixed-bumper MBL when cycling rapidly with enough mass to overwhelm a rubber stop. At 300mm of stroke, the unsupported Ø16mm rod is highly susceptible to side-loading and bending; the CA pivot clevis on this unit helps accommodate angular misalignment, but an external guide rail or a double-rod MBLCD type is strongly advised for rigid straight-line moves.
Replacement match: 40mm bore, 300mm stroke, G1/4 port, PT thread, CA pivot back cover, no magnet (non-S). Note that a plain double-acting cylinder drifts when air is lost or exhausted—the adjustable cushion only decelerates near the ends and does not function as a locking brake.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X300CA FAQ
This 40mm bore cylinder uses a G1/4 port and a Ø16mm rod with an M12x1.25 thread. It generates 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128kgf at 1.0MPa.
No, because this specific SKU lacks the -S suffix, it is manufactured without a built-in piston magnet, meaning CMSG reed or DMSG/EMSG electronic sensor switches cannot detect its position. You would need the MBLC40X300CAS variant to use sensors.
