| Performance characteristic: the bearing adopts the unit design, the axial clearance has already been matched according to the request, and does not need to readjust when installing. Bearing in manufacturing plants have been required to fill the special railway bearing grease, when assembled without adding grease, with both sides of labyrinth sealing device to prevent leakage of grease and prevent external impurities and dirt in. Bearing speed 120km/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 800 thousand km or 8 years, design life is greater than 1 million 600 thousand km. |
