About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450SU
The AirTAC MBLC40X450SU is a double-acting aluminum mini cylinder engineered for compact spaces requiring a 450 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a Ø16 mm carbon-steel rod with a 20 µm hard-chrome plating to resist wear. A defining feature is the screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly near stroke completion to reduce impact and vibration on fast or heavy moves.
This model includes a built-in magnet (indicated by the -S code) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position. The U code signifies a rigid flat-end back cover for straightforward mounting. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over long cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450SU Is Used
CNC Pallet Changer
Drives a 450 mm pallet transfer stroke on a machining center, using the adjustable cushion to gently decelerate a heavy tooling pallet and prevent end-cover damage at high cycle rates.
Packaging Pusher
Extends across a 450 mm lane to push filled cartons from a timing-belt conveyor, relying on the 628 N push force and smooth end-of-stroke damping to avoid jarring the products.
Vertical Lift Station
Raises a tote of components 450 mm in a tight assembly cell, utilizing the built-in -S magnet and DMSG electronic sensor to confirm the exact raised position before the next process step.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450SU the Right Cylinder?
When sizing this 40 mm bore cylinder, consider stepping down to the 32 mm bore (providing 402 N push at 0.5 MPa) for lighter loads, or up to the 50 mm bore (delivering 981 N push at 0.5 MPa) if your application demands greater thrust. Choose this MBLC variant over the base MBL when operating at high speeds or moving a heavier mass, as the fixed rubber bumper on the MBL cannot adequately absorb the kinetic energy that this adjustable air cushion handles.
At a 450 mm stroke, the 16 mm rod is highly susceptible to bending under side loads. To prevent premature wear, implement an external guide rail, use a pivot mounting style, or switch to an MBLD double-rod cylinder. Remember that the air cushion only decelerates the piston near the ends; it is not a brake. If the air supply is lost or exhausted, the rod will drift, so an external rod lock is required for position holding. This SKU uses a PT port thread and an M12x1.25 rod-end thread.
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 MBLC40X450SU FAQ
This 40 mm bore cylinder features a G1/4 port and an M12x1.25 rod-end thread. It delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa.
A screw-tunable needle at both ends of the cylinder traps a pocket of air to decelerate the piston smoothly just before the stroke ends. You tune this needle to match your specific load and speed, which cuts impact noise and vibration—unlike the fixed rubber bumper found on the standard MBL series.
