About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30SU
The AirTAC MBLC40X30SU is a double-acting aluminum mini cylinder engineered for compact actuation. It yields 628 N of push force and 528 N of pull force at 0.5 MPa. The 30 mm stroke is optimal for very short, high-frequency indexing tasks where immediate end-of-stroke impact control is necessary.
This unit features a screw-adjustable pneumatic cushion at both ends, allowing you to tune the needle to decelerate the piston smoothly and protect the end covers on faster or heavier moves. The riveted rolling-packed aluminum barrel keeps the body light and spatially efficient. It includes a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches, and a rigid U flat-end back cover for straightforward mounting.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30SU Is Used
Pick-and-Place Grippers
Drives short 30 mm jaw movements on packaging lines, using the 628 N push force to clamp corrugated cartons securely during transit.
Bottle Diverters
Executes rapid 30 mm indexing strokes to deflect plastic bottles on a filling conveyor, relying on the tunable air cushion to prevent harsh mechanical stops.
Component Ejectors
Pushes machined aluminum brackets out of a CNC fixture, utilizing the Ø16 hard-chrome carbon-steel rod to withstand repetitive ejection cycles.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30SU the Right Cylinder?
If you need less force, the Ø32 bore provides 402 N push at 0.5 MPa, whereas stepping up to the Ø50 bore yields 981 N. Choose this MBLC variant over the base MBL when your application cycles rapidly and the fixed rubber bumper cannot adequately absorb the kinetic energy. The cushion only decelerates the rod near the stroke ends; it is not a load lock, so an external rod lock is required to hold position without live air. The replacement match is bore 40, stroke 30, G1/4 port, M12x1.25 rod thread, PT thread form, U back cover, and magnet equipped.
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 MBLC40X30SU FAQ
At 0.5 MPa, it provides 628 N push and 528 N pull. At 0.7 MPa, the push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps exhaust air to decelerate the piston smoothly near the stroke limits. You adjust it to match the load and speed, which cuts impact noise and end-cover vibration on high-frequency moves. It only decelerates; it does not lock the load.
