    Roller bearings have the simplest structure. The inner ring and outer ring are in line contact with each other, so they have a large radial load capacity and are suitable for high-speed rotation. Bearings with collars or collars on both the inner and outer rings can receive axial loads, but they receive loads while sliding, so they cannot receive large axial loads.

    A cylindrical roller bearing is a bearing in which a cylindrical roller is sandwiched between an inner ring and an outer ring. Basic dimensions are determined by JIS standards. Since a cylindrical roller supports a load with a wire rather than a bearing using a steel ball, it should be used for a shaft portion where a large load is applied.
