The NKIS 25 RICH is a heavy-duty, single-row needle roller bearing with an inner ring, manufactured for demanding applications that require a high load-carrying capacity in a compact radial space. This precision-engineered bearing features machined outer and inner rings, which are separable from the needle roller and cage assembly, simplifying installation and maintenance procedures. The inclusion of the inner ring is a critical feature, making the NKIS 25 suitable for shafts that cannot be economically hardened and ground to act as a raceway. The single row of long, slender cylindrical rollers, guided by a robust steel cage, maximizes the contact area, ensuring efficient load distribution, high rigidity, and excellent performance under high radial forces. With dimensions of 25 x 47 x 22 mm, the NKIS 25 RICH is an ideal component for machine tools, transmissions, and heavy-duty industrial equipment where space-saving design is paramount.
Key Performance Advantages:
- High Load Capacity in Compact Design: The needle roller elements allow for a smaller cross-section while maintaining exceptional radial load resistance.
- Integrated Inner Ring: Provides a high-quality raceway surface, eliminating the need to harden or precision-grind the shaft itself.
- Separable Design: Facilitates straightforward mounting and dismounting of the components.
- High Stiffness: Machined rings and robust steel construction contribute to the bearing's overall rigidity and operational accuracy.
- Durable Steel Cage: The steel cage accurately guides the needle rollers, ensuring proper spacing and low friction.
