Matters needing attention when using grease for cylindrical roller bearings

wallpapers Resource 2020-05-20
1. Lubricate the bearing grease
 
The re-lubrication of cylindrical roller bearings is preferably carried out during planned plant downtime and replenished periodically while the old grease is removed or extruded through a drain. Clean the injection nozzle before adding fresh grease. If the FAG bearing box does not have an oil injection nozzle, the bearing box cover or end cover should be opened so that the old grease can be removed and fresh grease of the same type can be added after cleaning.
 
2. The bearing lubricating oil is lubricated
 
Check the oil level and oil quality of the lubricating oil regularly. In general, the normal oil level should be within the 1/3-2/3 range of the oil level window of the equipment or the label. The oil level displayed in the oil cup only represents the oil filling capacity, while the oil level of the cylindrical roller bearing box meets the operating requirements. The oil level in the oil cup is less than 1/4 of its total volume, so the oil filling can be considered.
 
Check and fill oil method, take out a small amount of lubricating oil as a sample and fresh lubricating oil for comparison, the competent unit may consider carrying out oil testing, in order to ensure the quality of oil qualified. If the sample looks cloudy, it may be the result of mixing with water, which is often referred to as oil emulsification. The lubricating oil should be changed at this time.
