BulletPoint1 : Code for top threaded outer spherical ball bearings: UC200 series (light series), UC300 series (heavy series), and deformation product UB (SB) 200 series. When the application environment is not suitable, UC200 series is usually selected, otherwise UC300 series is selected. Usually, there are two top threads on the outer spherical ball bearing, with an angle of 120 °. Its characteristic is that when cooperating with the shaft, the top threads are used to push against the shaft and then have a fixed effect. The cooperative environment requires a small oscillation scale. This type of outer spherical ball bearing is widely used in textile machinery, ceramic machinery, etc
BulletPoint2 : The codes for tapered outer spherical ball bearings are UK200 series and UK300 series. This type of outer spherical ball bearing has a tapered inner hole with an inner diameter of 1:12, which needs to be used in conjunction with a tightening sleeve. The characteristic of this type of outer spherical ball bearing is that it can accept larger loads than those with top screws. Due to the fact that the inner diameter of the same type of tight fitting sleeve used in cooperation with it is slightly smaller than that of the spherical ball bearing with a top screw
BulletPoint3 : The eccentric sleeve outer spherical ball bearings are designated as UEL200 series, UEL300 series, and SA200 series. The primary feature of this type of outer spherical ball bearing is that there is a certain degree of skewness at the upper end of the bearing, and a corresponding skewness sleeve with the same degree of skewness cooperates with it. This type of bearing can also be said to be a specialized bearing, as it is primarily used in agricultural machinery (harvesters, straw returning machines, threshers, etc.). This type of outer spherical ball bearing is mainly used in layouts with strong jumping, and cooperation in layout can effectively reduce strong jumping
BulletPoint4 : install Before installing the bearing on the shaft, it is necessary to first remove the fixing pin of the bearing sleeve, polish the surface of the shaft neck smooth and clean, and apply oil to the shaft neck for rust prevention and lubrication (allowing the bearing to rotate slightly on the shaft). Apply lubricating oil to the mating surface between the bearing seat and the bearing, and install the bearing into the bearing seat. Then fit the assembled bearing and bearing seat together onto the shaft and push them to the desired position for installation.
BulletPoint5 : Do not tighten the bolts of the bearing seat, let the bearing sleeve rotate inside the bearing seat. Install the other end bearing and base on the same shaft, rotate the shaft several times, and let the bearing align automatically. Tighten the bearing seat bolts again. Install the eccentric sleeve. Place the eccentric sleeve on the eccentric step of the bearing inner sleeve and tighten it by hand in the direction of shaft rotation. Insert the small iron rod into the countersunk hole on the eccentric sleeve. Use a hammer to strike the small iron rod in the direction of rotation along the axis to firmly install the eccentric sleeve and lock the hexagonal socket screw on the eccentric sleeve.
