18590 Nachi

Product Description

The 18590 Nachi is a single-row tapered roller bearing cone, consisting of the inner ring and rollers. When paired with a separate cup (outer ring), it forms a complete tapered roller bearing. This design allows the bearing to handle radial and axial forces in one direction. Its geometry prevents sliding, reducing wear, but requires a minimum load for proper operation. The cone and cup can be easily mounted and adjusted for axial clearance or preload during assembly. For reliable operation, it is recommended to replace both the cone and cup simultaneously and from the same manufacturer to prevent bearing problems. Always use a matching cup from the same manufacturer with the 18590 Nachi.
