32909 Tapered roller bearings

32909 Tapered roller bearings The tapered roller is a separated bearing, and the inner and outer rings of the bearing are provided with a conical raceway, and the roller is a round table shape. The roller is in line contact with the raceway, and can withstand heavy radial and axial combined loads, and can also withstand pure axial loads. The larger the contact Angle, the higher the axial carrying capacity. The design of the tapered roller should extend the contact line between the roller and the inner and outer raceway at the same point on the bearing axis to achieve pure rolling. The newly designed tapered roller bearing adopts the reinforced structure, the diameter of the roller is increased, the length of the roller is lengthened, the number of the roller is increased, and the bearing bearing capacity and fatigue life are significantly improved by using the convex roller. The contact between the big end face of the roller and the big rib is spherical and cone, which improves the lubrication. This kind of bearing can be divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed.
