The balls 3 and the cylindrical rollers 4 are alternately arranged in the peripheral direction. A recessed groove face 5 of the inner ring 1 serves as a raceway surface for the balls 3. Outer diameter faces 6, 6 on both sides serve as raceway surfaces for the cylindrical rollers 4. A recessed groove face 7 of the outer ring 2 serves as a raceway surface for the balls 3. Inner diameter faces 8, 8 on both sides serve as raceway surfaces for the cylindrical rollers 4. A cage 10 has two types of pockets 11, 12 for the balls 3 and the cylindrical rollers 4 in one cage itself. In this construction, radial load is mainly supported by the cylindrical rollers 4 and axial load is mainly supported by the balls 3.
