About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40U
The AirTAC MBLC63X40U is a compact double-acting aluminum mini cylinder featuring a screw-adjustable pneumatic cushion at both ends. It yields 1558 N push and 1457 N pull at 0.5 MPa, making this 40 mm stroke variant ideal for short, high-impact moves. The U code specifies a rigid flat-end back cover for straight-line thrust. Lacking the S suffix, this SKU has no internal magnet and cannot host a CMSG, DMSG, or EMSG position sensor.
Unlike the base MBL with its fixed rubber bumper, this MBLC lets you tune end-of-stroke deceleration to match heavy loads, protecting the end covers and lowering noise. The riveted rolling-packed aluminum barrel keeps the body light for tight spaces, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. The heterogeneous two-way grease-retaining piston seal maintains lubrication across the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40U Is Used
Injection Mold Ejection
Provides 1558 N of thrust at 0.5 MPa to eject heavy plastic parts from molds, using the tuned cushion to prevent harsh stops on the 40 mm stroke.
Press Brake Tooling
Drives short-stroke forming blades in metal fabrication, relying on the adjustable air cushion to absorb the 318 kgf peak load smoothly.
Pallet Diverting
Pushes loaded pallets sideways at transfer stations, using the rigid U flat-end cover to maintain alignment under high lateral momentum.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40U the Right Cylinder?
For slightly lower force needs, the 50 mm bore provides 981 N push at 0.5 MPa, while stepping up is not possible as 63 mm is the largest mini round size in this series. Choose this MBLC over a standard MBL when moving substantial mass at high speeds where a fixed bumper would degrade. Remember that the adjustable air cushion only decelerates near the stroke ends; it is not a locking mechanism. If the machine loses air, the rod will drift, so fit an external rod lock for fail-safe holding. This U flat-end configuration uses a PT tapered port and an M14x1.5 rod 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 MBLC63X40U FAQ
At 0.5 MPa, this 63 mm bore cylinder outputs 1558 N push and 1457 N pull. At 0.7 MPa, it yields 2181 N push and 2040 N pull. The maximum theoretical force is 318 kgf at 1.0 MPa.
No. Because the model code lacks an S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. You would need the MBLC63X40SU variant for solid-state or reed switch position detection.
