About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450CA
The AirTAC MBLC40X450CA is a double-acting aluminum mini cylinder engineered for a 450 mm stroke, delivering 628 N of push force and 528 N of pull force at 0.5 MPa. Because this SKU omits the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch. It is built for compact installations where reaching the end of a long stroke smoothly is critical to machine longevity.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You tune the needle valve to decelerate the Ø16 mm carbon-steel rod—coated with 20 µm hard chrome plating—as it approaches the end covers, effectively absorbing kinetic energy from fast or heavy loads. The riveted rolling-packed aluminum barrel keeps the body light, while the heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over high-frequency cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450CA Is Used
Textile Loom Tensioning
Drives a 450 mm carriage to position yarn guides, using the tunable cushion to prevent sudden jerks that would snap delicate threads during high-speed weaving.
Package Sorting Diverter
Pushes cardboard cartons across a logistics belt, where the CA pivot absorbs lateral side-load as the 628 N thrust arm arcs into the sorting lane.
PCB Panel Ejection
Extends fully to strip large motherboards from test fixtures, relying on the end-cover cushion to protect fragile solder joints from impact shock.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X450CA the Right Cylinder?
Select this 40 mm bore when you need 628 N of thrust at 0.5 MPa across a 450 mm span. If your application requires less force, stepping down to the 32 mm bore yields 402 N push and 346 N pull, whereas stepping up to the 50 mm bore provides 981 N push and 881 N pull. The CA pivot back cover is specifically designed to swing on a pin, making it ideal for arcing or angular loads that would bind a rigid flat-end U cover.
At 450 mm of travel, the 16 mm rod is highly susceptible to side-loading and bending; you must use an external guide rail, leverage the CA clevis pivot, or switch to an MBLD double-rod cylinder to prevent premature seal failure. Note that the adjustable air cushion only decelerates the piston near the stroke ends—it is not a mechanical lock. If the air supply is lost or the valve centers, the rod will drift, requiring an external pilot-operated check valve for position holding. This SKU uses a PT tapered port thread and cannot host a sensor switch.
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 MBLC40X450CA FAQ
This 40 mm bore cylinder uses a G1/4 port and a Ø16 mm rod with an M12x1.25 thread. It generates 628 N push and 528 N pull at 0.5 MPa, 880 N push and 739 N pull at 0.7 MPa, with a maximum theoretical force of 128 kgf at 1.0 MPa.
No. Because the model code lacks the -S suffix, this specific unit has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. If electronic or reed position detection is required, you must specify an MBLC40X450CAS variant.
