About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30CA
The AirTAC MBLC40X30CA is a double-acting aluminum mini cylinder with a 40mm bore and 30mm stroke. A screw-adjustable pneumatic cushion at both ends decelerates the piston smoothly near stroke limits, absorbing kinetic energy to protect the end covers on fast moves. It yields 628N of push force at 0.5MPa and 880N at 0.7MPa, making it suitable for short, powerful positioning tasks.
This CA variant uses a pivot clevis back cover that swings on a pin to accommodate arcing loads, unlike a rigid flat-end body. The riveted rolling-packed aluminum barrel keeps the frame compact for tight machine cells, while the 20-micron hard-chrome carbon-steel rod resists wear against the heterogeneous two-way grease-retaining piston seal. Note that this SKU lacks a built-in magnet, so it cannot host a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30CA Is Used
Pivot-Arm Actuation
Drives a 628N clamping arm on a packaging sealer, using the CA clevis to swing smoothly into position while the air cushion halts the short 30mm stroke without jarring the seal head.
Flight Transfer Diverter
Pushes lightweight cartons at transfer gates, relying on the tunable cushion to soften the 880N impact at 0.7MPa during high-frequency routing cycles.
PCB Shuttle Ejection
Ejects populated boards from a test fixture, where the compact riveted barrel fits the tight cell and the cushion prevents shock damage to delicate solder joints.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30CA the Right Cylinder?
For lower force needs, the 32mm bore neighbor provides 402N of push at 0.5MPa; for heavier lifting, the 50mm bore offers 981N. Choose this MBLC over the base MBL when your cycle speed or payload mass exceeds what a fixed rubber bumper can safely absorb. The adjustable needle tunes end-of-stroke deceleration but does not lock the rod—if you must hold position without live air, add an external rod lock or pilot-operated check valve. Replacement match: 40mm bore, 30mm stroke, G1/4 port, PT thread, CA pivot cover, no magnet.
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 MBLC40X30CA FAQ
At 0.5MPa it delivers 628N push and 528N pull. At 0.7MPa it yields 880N push and 739N pull. The maximum theoretical force is 128kgf at 1.0MPa.
A screw-tunable needle at each end restricts exhaust flow to trap air, decelerating the piston smoothly near stroke limits. You set the needle to match your load and speed, which cuts impact and vibration on the CA pivot joint. It only decelerates near the ends; it is not a load lock.
