NU 39/1060 ECKMA/HA1-Cylindrical roller bearing-FGFA bearings

NU 39/1060 ECKMA/HA1 Single row cylindrical roller bearing, NU design, with tapered bore

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.
