About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350CA
The AirTAC MBLC50X350CA is a double-acting aluminum mini cylinder with a 50 mm bore and 350 mm stroke, generating 981 N of push force and 881 N of pull force at 0.5 MPa. It features a screw-adjustable pneumatic cushion at both ends, allowing you to tune the end-of-stroke deceleration to match heavy loads and high cycling speeds, thereby reducing impact stress on the end covers. This model uses a CA pivot clevis back cover that swings on a pin to accommodate arcing or angular loads, which is essential for maintaining rod integrity over a 350 mm extension.
Unlike fixed-bumper designs, the adjustable cushion needle gives precise control over kinetic energy dissipation without acting as a load lock. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight for tight machine spaces, while the heterogeneous two-way grease-retaining piston seal and 20 µm hard-chrome plated carbon-steel rod ensure consistent friction and wear protection over many cycles. Because this specific SKU lacks the -S magnet suffix, it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350CA Is Used
Textile Loom Beater Mechanism
Drives the horizontal lay bar in a weaving machine, using the CA pivot to absorb angular vibration while the air cushion softens the 350 mm stroke reversal at high frequency.
Pallet Transfer Pusher
Kicks heavy pallets onto a perpendicular chain conveyor, where the 981 N push force clears the load and the cushion prevents end-cap shock during rapid ejection.
Automated Warehouse Diverter
Steers totes between sorting lanes, relying on the 350 mm reach and tunable deceleration to stop heavy goods smoothly without bouncing them off the guide rails.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350CA the Right Cylinder?
Step down to the 40 mm bore if your application requires less force (628 N push at 0.5 MPa), or step up to the 63 mm bore for heavy-duty moves requiring 1558 N push at 0.5 MPa. Choose this MBLC variant over the base MBL when your mechanism cycles rapidly or moves a substantial mass that would overwhelm a fixed rubber bumper. At 350 mm, the side-load bending moment on the 16 mm rod is significant; you must manage this with an external guide rail, the CA pivot clevis, or by switching to an MBLD double-rod cylinder. For position holding without live air, note that the cushion only decelerates near the ends and is not a brake; an external rod lock or pilot-operated check valve is required. The replacement match is bore 50, stroke 350, port G1/4, rod thread M14x1.5, PT port thread, CA back cover, and no magnet.

- ✓ 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 MBLC50X350CA 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.
A screw-tunable needle at each end restricts the exhaust air exiting the chamber near the stroke ends, compressing the trapped air to decelerate the piston smoothly. You adjust it to match the load and speed, which protects the end covers from impact. It is strictly a deceleration device, not a load lock or brake.
