Key Performance Advantages:
- Bi-Directional Axial Load Support: The four-point contact geometry enables this single-row bearing to manage significant axial forces in both directions. This design offers a space-saving alternative to double-row angular contact bearings.
- Premium Machined Brass Cage: The high-strength brass cage provides superior mechanical stability and excellent sliding properties. Being guided by the rolling elements, it ensures smooth rotation even under high speeds and heavy vibration.
- Yamaha OE Grade Precision: Engineered to match exact Yamaha specifications (93306 series), this bearing ensures perfect compatibility and long-term reliability for engine and transmission assemblies.
- High Load Density: By making contact at four distinct points on the raceways, the 6305 RBI FY RICH delivers high radial and axial rigidity, minimizing shaft deflection during intense operation.
- Reduced Mounting Space: The compact 17 mm width allows engineers to incorporate high axial load capacity into tight housing environments where a traditional double-row bearing would not fit.
Transparency Note: This bearing is manufactured under the RICH brand. The code 6305 RBI FY is used solely for identification and does not imply affiliation with other manufacturers.
