| Performance features: the overall structural design of the bearing, 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. Bearing speed 100km/h, the use of ambient temperature -45 degrees ~50 degrees, the use of temperature rise is not greater than 40 degrees, maintenance free cycle of 1 million km or 5 years, design life is greater than 3 million km |
