About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X50CA
The AirTAC MBLC40X50CA is a compact double-acting aluminum mini cylinder featuring a screw-adjustable pneumatic cushion at both ends. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, this 40 mm bore unit is built for short, rapid 50 mm strokes where fixed rubber bumpers would fail. Tuning the cushion needle lets you decelerate the piston smoothly near each stroke end, cutting end-cover impact, noise, and vibration on heavier moves without acting as a load lock.
This specific configuration uses a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, making it distinct from rigid flat-end mounts. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight spaces, while the Ø16 mm carbon-steel rod with 20 µm hard-chrome plating resists wear. Note that this SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X50CA Is Used
Package Diverting Arms
Drives a swinging diverter arm on a packaging conveyor. The CA pivot mount handles the angular load, while the 628 N push force easily redirects heavy cartons at high cycling speeds.
Textile Loom Beat-Up
Actuates the beat-up mechanism in a textile loom. The 50 mm stroke delivers rapid motion, and the adjustable air cushion absorbs the sudden deceleration to protect the end covers from impact.
Palletizing Gripper Tilt
Tilts a heavy gripper head during robotic palletizing. The cushion needle is tuned to soften the 50 mm stroke end, reducing mechanical shock that could damage the 40 mm bore assembly.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X50CA the Right Cylinder?
Select this 40 mm bore when your application requires the 628 N push force at 0.5 MPa but only a 50 mm stroke. If you need less force, stepping down to the 32 mm bore yields 402 N of push force; if you require more power, stepping up to the 50 mm bore provides 981 N. Choose this MBLC variant over the base MBL when your cycle speeds are high enough that the fixed bumper cannot absorb the kinetic energy, as the adjustable air cushion provides superior end-of-stroke protection.
Because this SKU uses a CA pivot mount, it is ideal for mechanisms requiring angular articulation rather than rigid linear guidance. Remember that a plain double-acting cylinder does not hold position when air is lost or the valve centers—the rod will drift. The cushion only decelerates near the ends; it is not a brake. For drop prevention, an external rod lock or pilot-operated check valve is required. This model uses a G1/4 port, M12x1.25 rod-end thread, and PT port thread form.
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 MBLC40X50CA FAQ
This 40 mm bore cylinder provides 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It uses a G1/4 port with a PT thread form and a Ø16 mm rod with an M12x1.25 end thread.
This specific SKU does not have a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. The adjustable air cushion at both ends is screw-tuned to decelerate the piston smoothly near the stroke ends, protecting the end covers on fast moves; it is not a locking brake.
