316083 A-Cylindrical roller bearing-FGFA bearings

316083 A Four-row cylindrical roller bearing

Cylindrical roller bearings feature cylindrical rollers as rolling elements and are classified as separable bearings. The rollers and raceways engage in line contact, enabling high load-carrying capacity. Primarily designed to accommodate radial loads, these bearings exhibit minimal friction between the rolling elements and the flange of the bearing ring, making them suitable for high-speed rotation. They offer exceptional load-carrying capability and maximum rotational speeds.
