NSK Auto Gearbox Ball Bearing B37-9AUR 37*85*13mm Deep Groove Ball Bearing

1. Improve lubrication quality, control oil pressure, temperature and flow, and strengthen oil filtration. 2. Use fuel oil and lubricating oil in accordance with the regulations. 3. control the temperature of the diesel generator set, in the case of supercooling and overheating work is unfavorable. In cold weather, the diesel engine should be preheated before starting, and turn the crankshaft by hand to make the oil enter the friction surface. 4.bearing and journal surface quality and geometric shape should be strictly guaranteed. 5. the bearing clearance should be appropriate, the generator set is too large to produce impact, too small, poor lubrication, may burn tile.

1. When the bearing is removed for inspection, the appearance record should be made by photography and other methods first. In addition, it is necessary to confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing. (1) The cleaning of bearings is carried out by rough washing and fine washing, and metal mesh can be placed at the bottom of the container used. (2) rough washing, in the oil with a brush to remove grease or adhesive. At this time, if you rotate in oil, pay attention to the rolling surface due to foreign bodies and other damage. (3) When fine washing, slowly rotate the bearing in the oil, and it must be carefully carried out. Usually used cleaning agent for neutral water - free diesel or kerosene, according to the need sometimes also use warm lye. No matter what kind of cleaning agent is used, always filter it to keep it clean. After cleaning, apply anti-rust oil or anti-rust grease to the bearing immediately. 2.inspection and judgment: in order to judge whether the removed bearing can be reused, we should focus on checking its dimensional accuracy, rotational accuracy, internal clearance and matching surface, raceway surface, cage and seal ring. Large bearings can not be rotated by hand, pay attention to check the appearance of rolling body, raceway surface, cage, retaining surface and so on. The more important the bearing is, the more carefully it must be checked.

1. Low noise 2. Low friction coefficient 3.Long durability
