FC218 Flanged Cartridge Bearing Unit

Housing Architecture: High-grade, single-piece cast iron round flanged housing with a machined pilot for precise concentric mounting.
Self-Aligning Capability: The spherical outer diameter of the insert bearing compensates for minor frame misalignment during installation.
Contamination Defense: Equipped with heavy-duty multi-lip seals and a protective slinger ring to aggressively block dust, crop debris, and moisture.

Deep Application & Technical Narrative:The FC218 is a robust, heavy-duty flanged cartridge bearing unit engineered for severe-duty agricultural machinery, bulk material conveyors, and industrial packaging equipment. The "FC" designation refers to a round, cast-iron flanged housing featuring a machined pilot hub. This pilot design allows the housing to be precisely mounted into a circular cutout in a machine frame, ensuring absolute concentricity and taking the shear load off the mounting bolts.
Inside this rugged housing sits a high-capacity insert bearing capable of accommodating initial static misalignment. In our dedicated assembly workshop, we never rely on automated blind checks. We manually inspect the locking set screws, verify the alignment of the grease zerk fitting with the internal bearing groove, and check the rotational smoothness of the insert. This strict hands-on quality assurance guarantees that your industrial clients receive a reliable, ready-to-mount unit that won't fail under heavy vibration.
Customized B2B Supply & Packaging Solutions:As a comprehensive B2B supplier, DBS Bearings provides a full range of mounted bearing units alongside standard rolling elements. The FC218 can be supplied in neutral heavy-duty industrial boxes or custom-branded packaging tailored to your regional distribution identity. We manage optimized maritime freight logistics to ensure these heavy cast-iron components reach your warehouses securely and cost-effectively.
Targeted Technical Clarifications (FAQ):

Q: Can the internal insert bearing be replaced without replacing the cast iron housing?A: Yes, the housing features a loading slot that allows a worn insert bearing to be rotated and removed, making field maintenance fast and economical.
Q: What type of locking mechanism does the FC218 use?A: It utilizes dual knurled cup-point set screws on the extended inner ring to lock securely onto the shaft, preventing slippage under heavy rotational torque.
