About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200U
The AirTAC MBLC40X200U is a double-acting aluminum mini cylinder with a 40 mm bore and 200 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for mid-weight positioning tasks. A defining trait of this SKU is the screw-adjustable pneumatic cushion at both stroke ends, which decelerates the piston smoothly to protect the end covers on fast or heavy moves.
This U back cover variant provides a rigid flat-end rear mount for straightforward in-line anchoring. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the carbon-steel rod features 20 µm hard-chrome plating to resist wear. Note that because this specific configuration lacks the -S magnet code, it cannot host a CMSG, DMSG, or EMSG sensor switch for position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200U Is Used
Packaging Carton Flap Folder
Uses the 628 N push force at 0.5 MPa to fold heavy cardboard flaps on a continuous packaging line, relying on the adjustable air cushion to silently halt the 200 mm stroke at high cycle rates.
CNC Lathe Bar Feeder
Indexes raw steel bar stock into a collet chuck; the 880 N push at 0.7 MPa provides the necessary authority to move the heavy material without slamming the tail end.
Palletizer Diverter Arm
Pushes incoming product boxes onto secondary accumulation lanes, utilizing the 200 mm stroke and tunable end-covers to prevent sudden stops that would shake the lightweight aluminum frame.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200U the Right Cylinder?
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 demands more power, the 50 mm bore provides 981 N push at 0.5 MPa. Choose this MBLC version over the base MBL when your cycle speeds or moving masses exceed what a fixed rubber bumper can safely absorb. Because this SKU uses a PT tapered thread and a U flat-end back cover, confirm your piping and mounting geometry match these specifications.
At a 200 mm stroke, the 16 mm rod is susceptible to bending under lateral stress. To manage side-load, use an external guide rail, select a CA pivot or SDB bracket if arcing motion is present, or switch to an MBLD double-rod cylinder. Remember that the adjustable cushion only decelerates the piston near the ends; it does not lock the rod, so the load will drift if air pressure is lost or the valve centers.
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 MBLC40X200U FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 880 N push and 739 N pull. The theoretical maximum is 128 kgf at 1.0 MPa. It features a G1/4 port, a 16 mm rod, and an M12x1.25 rod-end thread with PT (tapered) piping.
This specific SKU lacks the -S code, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. The cushion is a screw-tunable pneumatic chamber at both ends; you adjust the needle valve to match your load and speed, decelerating the piston smoothly near the stroke ends rather than relying on a fixed rubber bumper.
