About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450SCA
The AirTAC MBLC40X450SCA is a double-acting aluminum mini cylinder with a 40mm bore and 450mm stroke. It generates 628N of push force and 528N of pull force at 0.5MPa. A screw-adjustable pneumatic cushion at both ends decelerates the piston smoothly near stroke limits, absorbing kinetic energy from heavy or fast-moving loads to protect the end covers.
This specific configuration includes a CA pivot clevis back cover that swings on a pin to accommodate arcing angular loads, which is critical for a 450mm stroke. The riveted rolling-packed barrel keeps the body compact, while the 20um hard-chrome plating on the carbon-steel rod defends against wear. The built-in magnet (-S) enables position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450SCA Is Used
Textile Loom Beater
Drives the 450mm stroking motion on a weaving loom, using the CA clevis to pivot smoothly while the air cushion softens the high-frequency end-of-stroke impact.
Pallet Transfer Pusher
Transfers heavy components across a packaging conveyor, relying on 628N of push force at 0.5MPa to clear the lane before the next cycle.
Vertical Lift Gate
Raises a compact access panel on a sorting machine, where the tunable cushion prevents the 450mm stroke from slamming the top cover under gravity.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450SCA the Right Cylinder?
For a 40mm bore, the 450mm stroke suits long-travel pushing and lifting. If you need less force, step down to the 32mm bore (402N push at 0.5MPa); if moving heavier masses, step up to the 50mm bore (981N push at 0.5MPa). Choose this MBLC variant over the base MBL when cycling speeds are high enough that a fixed rubber bumper would fail to absorb the impact.
At 450mm, the Ø16 rod has a low side-load tolerance and is prone to bending; use an external guide rail, the CA pivot, or an MBLD double-rod cylinder to prevent damage. Note that the adjustable cushion only decelerates motion near the ends—it is not a lock. A plain double-acting cylinder drifts when air is removed. Replacement match: 40mm bore, 450mm stroke, G1/4 port, PT thread, CA back cover, magnet installed.
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 MBLC40X450SCA FAQ
At 0.5MPa it provides 628N push and 528N pull. At 0.7MPa it provides 880N push. The maximum theoretical force is 128kgf at 1.0MPa. It uses a G1/4 port, a Ø16mm rod, and an M12x1.25 rod-end thread.
The cushion needle is screw-tunable to decelerate the piston near both stroke ends, protecting the end covers from high-speed impacts. The built-in magnet (-S) allows CMSG reed switches, as well as DMSG or EMSG solid-state sensors, to detect rod position along the 450mm travel.
