Horn exposed to ball bearing give, keep in touch the ball bearing for the intersection of uniline and corner. Pair lists the angle and contacts the ball bearing, contact the bearing at four o’clock, the angle contacts the ball bearing, can bear radial load and axial load at the same time, also can bear purely axial load, the terminal rotational speed is relatively high, the ability of the axial load born is determined by the fact that exposed to the angle all kinds ofly, it is the bigger to be exposed to the angle, the larger the axial load born is, exposed to the angle as 15, 25, 40, three kinds. When bearing radial load, will cause additional axial force, so must exert the corresponding reverse axle load, should generally use in pairs. Install and use and divide installing for the back-to-back way again in pairs, install three kinds in face-to-face way installation and serial fashion
