About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300CA
The AirTAC MBLC50X300CA is a double-acting aluminum mini cylinder with a 50 mm bore and 300 mm stroke, engineered for demanding arcing movements. It generates 981 N of push force and 881 N of pull force at 0.5 MPa. Unlike standard rigid-body cylinders, this variant uses a CA pivot clevis back cover that swings on a pin to absorb angular misalignment during side-loaded rotational travel. The riveted rolling-packed aluminum barrel keeps the overall body compact and lightweight, avoiding the bulk of a traditional tie-rod rebuildable construction.
This model relies on a screw-adjustable pneumatic air cushion at both stroke ends to smoothly decelerate the piston, minimizing end-cover impact and vibration on heavier loads. It uses a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating and a heterogeneous two-way grease-retaining piston seal for lasting friction control. Because this specific SKU lacks the built-in magnet suffix (-S), it cannot accommodate CMSG, DMSG, or EMSG position sensing switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300CA Is Used
Automated Welding Arm Actuator
Drives a heavy MIG welding head through a 300 mm arc on an automotive chassis line, utilizing the CA pivot clevis to accommodate the angular rod movement while the air cushion prevents jarring stops at high traverse speeds.
Heavy Parts Diverter Gate
Pushes a 900 N steel casting diverter on a roller conveyor, relying on the 981 N push force at 0.5 MPa and the tunable end-cushioning to smoothly cycle 30+ times a minute without hammering the pivot brackets.
Palletizing Carton Sweep
Sweeps large corrugated cartons into a palletizing stack, where the 300 mm stroke provides the necessary reach and the adjustable needle valve softens the impact of the 16 mm rod at the end of each rapid extend motion.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300CA the Right Cylinder?
At 0.5 MPa, this 50 mm bore yields 981 N push and 881 N pull. If your application requires less force, stepping down to the 40 mm bore provides 628 N push and 528 N pull. If you need substantially more power, the 63 mm bore offers 1558 N push and 1457 N pull. Choose this MBLC cushioned version over the base MBL bumper type when your mechanism cycles quickly or carries enough mass that a fixed rubber bumper would transmit destructive shock loads to the machine frame. Keep in mind the air cushion only decelerates the piston near the end of travel; it is not a mechanical lock and will not hold the load in place if air pressure is dropped or the valve centers.
This 300 mm stroke pushes the limits of the compact Ø16 mm rod, creating a high risk of rod bending under side loads. For this configuration, the CA pivot back cover is essential to allow the cylinder body to articulate. You should also incorporate an external linear guide, use an SDB pivot bracket, or switch to an MBLD double-rod cylinder to prevent rod deflection and premature seal wear. The G1/4 port and M14x1.5 rod-end thread are fixed to this 50 mm bore size, with PT (tapered) threading as the default port form.

- ✓ 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 MBLC50X300CA FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
The cushion is a screw-tunable pneumatic needle at both ends that traps exhaust air to decelerate the piston smoothly before it hits the end cover, which is critical for protecting the machine from heavy impacts. This specific MBLC50X300CA SKU does not have a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors without changing to an -S designated model.
