The B-138 RICH is a high-performance needle roller bearing without an inner ring, designed for applications where radial space is extremely limited. This full complement design utilizes a maximum number of rollers, which provides a very high load-carrying capacity within a minimal cross-section. By omitting the inner ring, the bearing uses the shaft itself as the inner raceway, which must be hardened and ground to an appropriate surface finish for optimal performance. The drawn outer cup and full complement of rollers make this bearing a compact and robust solution for heavy-duty applications. The B-138 RICH is ideal for use in automotive transmissions, power tools, and other machinery requiring a slim, yet powerful, bearing solution.

Key Performance Advantages:

  • High Load Capacity: Full complement design allows for maximum load-carrying capability.
  • Compact Design: The absence of an inner ring provides a very low-profile solution.
  • Space-Saving: Uses the shaft as the inner raceway, perfect for applications with limited radial space.
  • Durable Construction: Built for reliable performance in demanding environments.
  • RICH Quality: Engineered for precision and consistent performance.
