387A A&S – Fersa

The 387A A&S – Fersa is a removable cone for a single-row tapered roller bearing, which includes the inner ring and rollers. It is designed to be paired with a separately available cup to create a complete tapered roller bearing, capable of absorbing radial and axial forces in one direction. The unique design prevents sliding movements between the raceways and rollers, reducing wear and ensuring reliable operation. To achieve proper bearing operation, it is important to maintain a minimum load. The cone and cup can be easily mounted and adjusted for end play or preload during assembly. For optimal performance, it is recommended to replace both the cone and cup at the same time and to use components from the same manufacturer to avoid potential bearing problems.
