BC4-0093-Cylindrical roller bearing-FGFA bearings

BC4-0093 Four-row cylindrical roller bearing, for long products

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.
