SL1818,NCF 1840 series are single row full complement cylindrical roller bearings.Which have solid outer and inner rings together with rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage.
Single row full complement cylindrical roller bearings are in the form of semi-locating bearings.
