The NKIS 55 RICH is a heavy-duty, single-row needle roller bearing with an inner ring, manufactured for high-performance applications that demand maximum radial load capacity within a minimal cross-sectional envelope. Bearing dimensions are 55 x 85 x 28 mm.

This precision-machined bearing from RICH is characterized by its separable design, featuring a robust outer ring with integral flanges and a removable inner ring. The inclusion of the inner ring is ideal for setups where the shaft surface cannot be hardened and ground to serve as a raceway, providing a ready-to-use, high-precision raceway for the rolling elements. The long, slender needle rollers are precisely guided by a durable steel cage, ensuring optimal alignment and load distribution, which results in excellent stiffness and reduced friction under strenuous conditions. The NKIS 55 is a reliable choice for use in heavy machinery transmissions, automotive components, and industrial equipment.

Key Performance Advantages:

  • High Radial Load Capacity: Delivers superior performance for heavy static and dynamic loads due to the large number of rolling elements in a compact space.
  • Integrated Inner Ring: Provides a high-quality raceway, allowing the bearing to be mounted on shafts that are not suitably finished or hardened.
  • Separable Design: The components (outer ring, inner ring, and roller/cage assembly) can be mounted independently, simplifying assembly and maintenance procedures.
  • High Stiffness: Machined rings offer excellent rigidity, ensuring precision and reliability in demanding operational environments.
  • Robust Steel Cage: The high-strength steel cage maintains roller alignment and is built for long service life.
