The NKIS 15 RICH is a single-row needle roller bearing with an inner ring designed to offer maximum load-carrying capacity in bearing arrangements with limited radial space. With dimensions of 15 x 35 x 20 mm, this compact, heavy-duty bearing from RICH is ideal for precision applications where a high degree of rigidity is required.
This bearing features precision-machined rings and a high-strength steel cage that accurately guides the long, slender needle rollers. The inclusion of an inner ring makes the NKIS 15 particularly valuable when the shaft cannot be induction hardened and ground to serve as a direct raceway, ensuring a pre-engineered, high-quality rolling surface. The design is separable, meaning the inner ring can be mounted separately from the outer ring assembly, which simplifies the installation process. The robust construction and heavy-duty characteristics make it suitable for power tools, automotive transmissions, and various industrial machinery applications.
Key Performance Advantages:
- Exceptional Radial Load Capacity: The large number of needle rollers provides a significantly high capacity for static and dynamic radial loads relative to its small cross-section.
- Integrated Inner Ring: Ensures reliable performance and high running accuracy, even when the surrounding shaft is not sufficiently hardened or ground.
- High Stiffness and Rigidity: Machined outer and inner rings contribute to the bearing’s overall structural integrity, ensuring minimal deflection under load.
- Compact, Space-Saving Design: The low cross-sectional height allows for miniaturization and weight reduction in machinery design.
- Durable Steel Cage: Provides excellent guidance for the rolling elements, maintaining alignment and ensuring consistent, long-life operation.
