With the development of science and technology, robots gradually spread from aerospace defense field to our life. There are many kinds of robots, whose work have big distinction, but lots of robots will use large quantities of bearings. Robots imitate human body structure and their hands, foots and shoulder need to rotate, so it need bearing's help to complete complex action. There are lots of bearings used by industrial robots. One kind is cross cylindrical roller bearing and the other kind is uniform and thin section bearing. What so called cross cylindrical roller bearing is that its inner structure adopts 90 degrees perpendicular cross array and interval retainer or isolation block is installed between rollers to prevent from leaning and friction. Cross cylindrical roller bearing has the following characteristics: high precision, bearing axial and radial loads, small size space and easy to install. Our main bearing types are XRB type, XRE type and XRU type and so on. While four point angular contact ball bearing is the most typical type of uniform and thin section bearing. Four point angular contact ball bearing is a kind of bearing which can be separated, and its inner steel balls and inner and outer rings are four point contact. Four point angular contact ball bearing can also bear axial and radial loads and has the advantages of small axial clearance and high precision, which can reach to P4 and P2 grade. Its main models are QJF0000, QJ0000, KB180CP0, KB120AROA, KA040CPO, KC047CPO and KC160CPO and so on.
