About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X400CA
The AirTAC MBLC50X400CA is a double-acting aluminum mini cylinder engineered with a 50 mm bore and 400 mm stroke. It generates 981 N of push force and 881 N of pull force at 0.5 MPa. Because this SKU omits the -S suffix, it lacks a built-in magnet and cannot accept a CMSG, DMSG, or EMSG position sensor. The CA back cover provides a pivot clevis that articulates on a pin, accommodating angular rod deflection during long-travel arcing motions.
This model relies on a screw-adjustable pneumatic air cushion at both ends rather than a fixed rubber bumper. Tuning the cushion needle decelerates the piston smoothly near each stroke limit, cutting end-cover impact on high-speed or heavy-mass moves. The riveted rolling-packed aluminum barrel keeps the body compact, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist wear. A heterogeneous two-way grease-retaining piston seal helps maintain consistent friction over the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X400CA Is Used
Textile Loom Beam Indexing
Drives the 400 mm arcing stroke of a heavy weaving beam indexer. The CA pivot absorbs lateral rod sway, while the adjustable cushion halts the 981 N push force smoothly at high cycling speeds.
Package Sorter Diverter Arm
Actuates a long diverter arm on a high-speed logistics conveyor. The 881 N pull force retracts the 400 mm stroke rapidly, and the tuned air cushion prevents end-cap knock during rapid sorting cycles.
Palletizing Vacuum Head Lift
Lifts a vacuum gripper head over a 400 mm gap to engage tiered pallet loads. The compact riveted barrel fits tight vertical gantries, and the cushion protects the pivot pin from sudden shock loads.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X400CA the Right Cylinder?
At 0.5 MPa, this 50 mm bore yields 981 N push and 881 N pull. If your payload is lighter, the 40 mm neighbor provides 628 N push, whereas stepping up to the 63 mm bore grants 1558 N push for heavier masses. Choose this MBLC variant over the base MBL when your cycle speeds or moving masses exceed what a fixed rubber bumper can absorb. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a mechanical lock, so the rod will drift if air pressure is lost or the valve centers.
With a 400 mm stroke, the Ø16 rod is highly susceptible to bending under side loads. For this travel length, you must support the load with an external guide rail, leverage the CA pivot clevis to absorb angular misalignment, or switch to an MBLD double-rod cylinder to prevent rod deflection and premature seal failure. The PT tapered port threads directly into standard pneumatic fittings.

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 MBLC50X400CA FAQ
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod with an M14x1.5 rod-end thread, and standard PT tapered port threads.
The cushion is a screw-tunable pneumatic needle at both ends that traps exhaust air to decelerate the piston smoothly near the stroke limits, protecting the end covers on fast moves. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG electronic position sensors.
