About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X50U
The AirTAC MBLC40X50U is a compact double-acting aluminum mini cylinder engineered for short-stroke actuation. It produces 628 N of push force and 528 N of pull force at 0.5 MPa, driven by a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating. The 50 mm stroke is optimal for compact ejection or clamping tasks. Unlike the base MBL, this variant uses a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke limits, minimizing end-cover impact on faster cycles. It is a deceleration device, not a load lock.
The riveted rolling-packed aluminum barrel keeps the body light for tight-fitting machinery. A heterogeneous two-way grease-retaining piston seal maintains lubrication over high-frequency moves. The U flat-end back cover provides rigid rear mounting. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot host a CMSG, DMSG, or EMSG position sensor. Porting is G1/4 with a PT thread form, and the rod-end thread is M12x1.25.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X50U Is Used
Injection Mold Ejection
Provides 628 N of push at 0.5 MPa to eject plastic parts from molds. The 50 mm stroke and adjustable air cushion prevent harsh impacts during rapid mold-open cycles, protecting the end covers.
Packaging Line Diverter
Pushes cartons at high speed on a packaging line. The tunable cushion smoothly halts the 50 mm stroke, reducing machine vibration and noise without needing a bulky ISO 15552 body.
Benchtop Pressing
Performs light-duty pressing or staking of small components. The rigid U flat-end back cover mounts firmly to bench frames, while the 880 N push force at 0.7 MPa handles stubborn inserts.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X50U the Right Cylinder?
Choose this 40 mm bore when your application requires around 628 N of push force at 0.5 MPa. If your load is lighter, the 32 mm bore offers 402 N of push force; for heavier demands, the 50 mm bore provides 981 N. The adjustable air cushion is the primary reason to select this MBLC over the fixed rubber bumper of the standard MBL, specifically when operating at high speeds or moving a heavier mass that would prematurely wear a fixed bumper. A plain pneumatic cylinder does not hold position when air is lost or the valve centers; the rod will drift. The cushion only decelerates near the ends, so for true position holding without live air, install an external rod lock or pilot-operated check valve. Replacement parts must match the 40 mm bore, 50 mm stroke, G1/4 port, PT thread, and U flat-end back cover.
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 MBLC40X50U FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No. Because the model code lacks the -S suffix, this specific unit is manufactured without a built-in magnet and cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches for rod position detection.
