For as long as possible in good condition to maintain the performance of the cylindrical roller bearing was required to maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. As maintenance issues in the operation, koyo bearing the rotation of the sound, vibration, temperature, the state of the lubricants and so on. Bearing cleaning: removing cylindrical roller bearing under repair, the appearance of the first record koyo bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, if make cylindrical roller bearings with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Bearing a cracked peeling for koyo bearings under the action of cyclic load, the contact surface fatigue damage is easy to occur, so in order to improve the service life of bearing, bearing steel must have a high contact fatigue strength. Hardness is one of the important quality of cylindrical roller bearing quality, the contact fatigue strength, wear resistance, elastic limit has a direct impact. Cylindrical roller bearing steel in the condition of using the hardness of general to achieve HRC61 ~ 65, koyo bearings can obtain high contact fatigue strength and wear resistance. Cage is made of nylon 46, reduce the sliding friction between the ball and cage. Also, eliminates the direction of rotation of concave and convex shape, which reduces the mixing loss. In addition, by using can slow down the assembly of the shape of the stress, to ensure that the assembly performance. A single keep frame loss torque decreased 30 ~ 40%, cylindrical roller bearing torque reduces the 50 ~ 65% overall losses. The company to speculate that the prius will model of 10 and 15 fuel efficiency from past 35. 5 km/L up to 38. 0 km/L, improve fuel efficiency by about 1 ~ 2% is achieved by using this kind of bearing. Koyo bearing parts in the process of production, after a lot of cold and hot working process, in order to meet the requirements of mass, high efficiency, high quality, cylindrical roller bearing steel should have good processing performance. For example, the cold and hot forming properties, machinability, hardenability, etc.
