| Performance features: the overall structure of the cone bearing structure design, radial clearance and axial clearance has been adjusted according to the standard, no need to re adjust the installation. Bearing in the manufacturing plant has been required to fill the special railway bearing grease, assembled without adding grease, both sides with a sealed cover, to prevent leakage of grease and prevent external impurities and dirt immersion. Cylindrical roller bearings are used in pairs. The and EC structure are adopted. The roller element adopts logarithmic curve, and the edge of the roller adopts oblique edge to reduce the edge stress and improve the axial bearing capacity of the bearing. The radial clearance of the bearing and the matching axial clearance have been matched according to the requirements, and no adjustment is needed during the installation. Bearing speed 80km/h, the use of ambient temperature -40 degrees ~40 degrees, the use of temperature rise is not greater than 30 degrees, bearing maintenance cycle of 6 years, design life is greater than 2 million km. |
