The NKIS 30 RICH is a heavy-duty, single-row needle roller bearing with an inner ring, manufactured to deliver exceptional performance in applications with restricted radial space. With compact dimensions of 30 x 52 x 22 mm, this bearing from RICH is engineered for high load-carrying capacity and high stiffness.

This NKIS series bearing is a separable unit, meaning the precision-machined inner ring can be mounted independently of the outer ring and roller assembly. This design feature simplifies assembly, especially when the shaft itself cannot be used as a hardened and ground raceway. The bearing utilizes a robust steel cage to accurately guide the numerous long, slender needle rollers, ensuring proper load distribution and high running accuracy. The combination of a compact cross-section and high performance makes the NKIS 30 ideal for use in industrial gearboxes, machine tools, and heavy-duty transmission systems.

Key Performance Advantages:

  • High Radial Load Capacity: Due to the large number and small diameter of the needle rollers, the bearing provides superior capacity for static and dynamic radial loads in a compact envelope.
  • Integrated Inner Ring: The inner ring provides a precise, hardened raceway surface, ensuring consistent bearing performance even when the shaft quality is not optimized for a direct roller interface.
  • Excellent Rigidity and Stiffness: The robust design with machined rings maintains high dimensional stability and minimal elastic deformation under heavy operating conditions.
  • Space-Saving Profile: Offers a highly efficient solution for machinery where minimizing radial space and weight is critical.
  • Durable Steel Cage: The high-strength cage accurately separates and guides the rollers, contributing to reduced friction and extended service life.
