About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10U
The AirTAC MBLC40X10U is a double-acting aluminum mini cylinder with a 40 mm bore and 10 mm stroke, delivering 628 N push and 528 N pull force at 0.5 MPa. Its defining feature is the screw-adjustable pneumatic cushion at both ends, which allows you to dial in end-of-stroke deceleration for rapid, high-frequency short strokes. This protects the end covers from impact damage far better than a fixed rubber bumper. The U suffix denotes a rigid flat-end back cover for direct mounting.
Built with a riveted rolling-packed aluminum barrel, the body remains compact and lightweight for tight machine layouts. The 20 µm hard-chrome plating on the carbon-steel rod resists wear, while the heterogeneous two-way grease-retaining piston seal maintains smooth operation across the 30-800 mm/s speed range. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10U Is Used
Injection Mold Ejection
Provides a fast 628 N push to knock short-run plastic parts out of a mold, using the tuned air cushion to prevent slamming the mold plate over millions of 10 mm cycles.
Packaging Lane Diverter
Snaps a lightweight cardboard carton into a secondary packaging lane with a 10 mm jab, relying on the adjustable cushion to brake the piston before it strikes the rear flat-end cover.
PCB Test Press
Applies a brief 528 N pull to seat an electronic test fixture onto a circuit board, absorbing the shock of the rapid 10 mm retraction so sensitive nearby sensors do not vibrate.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10U the Right Cylinder?
At 10 mm of stroke, this model is purpose-built for extremely short, high-impact transitions. If you need less force, the next size down is the 32 mm bore, offering 402 N push at 0.5 MPa. If your application requires more thrust, the 50 mm bore provides 981 N push at 0.5 MPa. Choose this MBLC variant over the base MBL specifically because the short stroke cycles rapidly, requiring precise needle tuning to prevent end-cover shock. Because the 16 mm rod has low side-load tolerance, keep the load strictly axial. Finally, this U-flat-end, PT-threaded, non-magnetic configuration does not hold position without live air; use an external rod lock if the load must be secured during exhaust.
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 MBLC40X10U FAQ
This 40 mm bore cylinder uses a G1/4 port and a 16 mm rod with an M12x1.25 thread. It generates 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and reaches a maximum theoretical force of 128 kgf at 1.0 MPa.
A screw needle at each end traps a pocket of exhaust air to decelerate the piston smoothly before it hits the cover. You tune the needle to match the load and speed of the 10 mm stroke. It is strictly a braking mechanism and does not lock or hold the rod in place when air is removed.
