Product Overview

The 6308 2RS C5 RH1 RICH is a premium **Single Row Deep Groove Ball Bearing** built for high-performance applications where maximum speed and significant heat generation are factors. Manufactured by RICH, this bearing is a robust component designed to handle both radial and moderate axial loads with outstanding efficiency, providing the reliability needed for demanding automotive and industrial machinery.

The key features of this model are the double-sided rubber contact seals (2RS) and the C5 internal clearance. The 2RS seals provide an effective, maintenance-free barrier, sealing in the long-life grease while protecting against water and fine particulate contaminants. The C5 clearance is greater than the standard C3 and C4, making it specifically suited for applications that operate at very high speeds or where extreme thermal expansion might occur, preventing premature failure due to binding. With precise dimensions of 40 x 90 x 28 mm and an outer ring width (C) of **23 mm**, the 6308 2RS C5 RH1 RICH offers a high-quality, dependable interchange for numerous references, including Toyota 90363-40068.

Key Performance Advantages:

• C5 Internal Clearance: Optimized for high-speed operation and severe thermal expansion conditions.
• Maximum Protection (2RS): Contact seals provide superior defense against moisture and fine contamination.
• High Versatility: Efficiently handles combined radial and axial loads across a wide range of speeds.
• Wide Interchangeability: Reliable replacement for numerous OE and aftermarket references, including Toyota 90363-40068.

Transparency Note

The 6308 2RS C5 RH1 bearing is manufactured by RICH in China to meet stringent quality and dimensional standards, ensuring reliable interchangeability and performance.
