NJ305C3, Cylindrical Roller Bearing The cylindrical rollers are in linear contact with the raceways They have a high radial load capacity and are suitable for high-speeds The outer and inner rings of all types are separable Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other These can be used as free-end bearings Cylindrical roller bearings, in which either the inner or outer ring has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tool
