Smaller bearings typically have integral outer ring langes and often have one-piece inner rings. Bearings up to 400 mm bore diameter are usually manu-factured with roller-centered, dou-ble-pronged machined cages made from brass or steel. Larger bearings normally have a steel pin-type cage for each of the four rows of rollers.
