Key Performance Advantages:
C3 Internal Clearance: Designed with an internal radial clearance greater than normal, this bearing prevents seizing and internal stress by accommodating thermal expansion during continuous high-speed operation.
Yamaha OE Grade Performance: Engineered as a high-quality interchange for Yamaha reference 93306-20712, ensuring seamless integration into motorcycle engines and drivetrain assemblies.
High-Speed Steel Cage: The robust steel cage provides excellent ball guidance and durability, maintaining structural integrity under the high centrifugal forces typical of transmission environments.
Low-Friction Open Design: The open configuration (no seals) allows for immediate lubrication by the system's oil bath, ensuring superior heat dissipation and reduced rolling resistance.
Versatile Load Support: The deep groove geometry enables the bearing to support high radial loads as well as moderate axial loads in both directions, providing stable shaft rotation for mission-critical components.
Transparency Note: This bearing is manufactured under the RICH brand. The code 6207 YR9 C3 is used solely for identification and does not imply affiliation with other manufacturers.
