NA643 Timken

The NA643 Timken is a cone specifically designed for a single-row tapered roller bearing. It comprises the inner ring and rollers of the bearing. To complete the tapered roller bearing, it needs to be paired with a separately available cup (or outer ring). The conical raceways and tapered rollers allow the bearing to effectively handle radial and axial forces. Due to its design, the bearing prevents sliding movements between the raceways and rollers, thus minimizing component wear. It’s important to note that a minimum load is required for proper bearing operation. The cone and cup can be easily mounted and adjusted for end play or preload during assembly. For optimal performance, it’s recommended to replace the cone and cup at the same time, and to use components from the same manufacturer to prevent bearing problems due to differences in profiles, material, or tolerances. Always pair the NA643 Timken with a matching cup from the same manufacturer for reliable operation.
