Performance features: the overall compact type of structural design, the axial clearance has been required to match, installation without re adjustment. Bearing in manufacturing plants have been required to fill the special railway bearing grease, when assembled without adding grease, both with low torque sealing device to prevent leakage of grease and prevent external impurities and dirt in. Bearing speed 100km/h, the use of ambient temperature -40 degrees ~40 degrees, the use of temperature rise is not greater than 55 degrees, maintenance free cycle of 600 thousand km or 6 years, design life is greater than 1 million 600 thousand km. |
