These precision-engineered tapered roller bearings are essential components for machinery and equipment requiring reliable rotational support under heavy radial and thrust loads. The 387A/382A bearing set features a robust single-row design with a 57,15mm bore diameter, 96,84mm outer diameter, and 21,95 mm width, providing optimal load distribution and smooth operation. Manufactured from durable chrome steel to ABEC 3 specifications, these bearings deliver consistent performance in demanding applications. The tapered roller design efficiently handles combined loads, making them ideal for automotive wheel hubs, gearboxes, and industrial machinery. This package includes 2 complete bearing assemblies, each consisting of a cone and cup, ready for installation. The precision-ground raceways and hardened construction ensure long service life and minimal friction, while the tapered geometry provides superior load-carrying capacity compared to standard ball bearings. Whether performing maintenance, repairs, or new installations, these bearings offer the reliability required for critical rotating applications.
