About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X225CA
The AirTAC MBLC40X225CA is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, this 40 mm bore unit is built for dynamic cycles where a fixed rubber bumper would fail. The 225 mm stroke provides ample travel for intermediate positioning tasks. Because this SKU lacks the -S suffix, it has no internal magnet and cannot support CMSG, DMSG, or EMSG position sensing.
A defining feature of this configuration is the CA pivot back cover, which swings on a pin to accommodate arcing or angular loads. This is paired with a heterogeneous two-way grease-retaining piston seal and a 20 µm hard-chrome plated carbon-steel rod. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the G1/4 port and M12x1.25 rod-end thread handle the necessary airflow for high-speed 30-800 mm/s operation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X225CA Is Used
Pick-and-Place Arms
Drives the horizontal swing arm on a packaging machine, using the CA pivot to absorb angular momentum while the air cushion decelerates the 225 mm stroke smoothly at 800 mm/s.
Pallet Diverters
Pushes loaded pallets off a main conveyor line, utilizing the 628 N push force at 0.5 MPa to overcome friction without slamming the end cover.
Hinge-Style Lid Lifters
Opens heavy industrial access panels on machinery, where the CA clevis accommodates the changing arc geometry and the cushion prevents sudden drops at the end of travel.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X225CA the Right Cylinder?
Select this 40 mm bore when your application requires 628 N of push force at 0.5 MPa. If you need less force, step down to the 32 mm bore providing 402 N push; if you require more power, step up to the 50 mm bore delivering 981 N push. The CA clevis back cover is essential here for arcing loads, contrasting with the rigid U flat-end default. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake. A plain cylinder does not hold position if air is lost, so add an external rod lock for fail-safe holding.
At 225 mm of stroke, the Ø16 rod is susceptible to bending under heavy lateral stress. To manage side-load, use the CA pivot to self-align the load, install an external guide rail, or switch to an MBLD double-rod cylinder. This PT-threaded model uses a standard 225 mm stroke (under the 500 mm max standard limit), meaning it is readily available rather than a special-order length.
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 MBLC40X225CA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull force. At 0.7 MPa, it outputs 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa. It features a G1/4 port, an M12x1.25 rod-end thread, and a PT tapered port thread form.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston before impact, protecting the end covers on fast or heavy moves. Because this specific SKU lacks the -S magnet suffix, you cannot mount CMSG, DMSG, or EMSG sensor switches to detect rod position.
