Precautions for using grease in IKO one-way bearings
Jan 23, 2019

Lubrication is a must in the process of using one-way bearings. However, there are many ways to lubricate. Various lubrication methods should pay attention to the problems in the lubrication process, which leads to users. The confusion, today I will introduce you to the precautions for IKO bearing oil lubrication and grease.

1, grease lubrication

    Relubrication of IKO bearings is best carried out during planned equipment downtime and is periodically replenished, while removing old grease or extruding old grease through the drain. Wipe the grease fittings clean before adding fresh grease. If the one-way bearing housing does not have a grease fitting, the bearing housing cover or end cap should be opened to remove the old grease and, after cleaning, replenish the same type of fresh grease.

2, lubricating oil lubrication

    Regularly check the oil level and oil quality of the lubricating oil. Under normal circumstances, the normal oil level should be within the range of 1/3-2/3 of the equipment oil level window or mark. The oil filling method is oil cup, the oil level shown only represents the oil replenishing capacity, and the oil level of IKO bearing housing is to meet the operation requirements. The oil level in the oil cup is less than 1/4 of its total volume.

    Check and replenish the oil method, take a small amount of lubricating oil as a sample and compare it with fresh oil. The competent unit can consider the oil quality test to ensure the oil quality is qualified. If the sample looks cloudy, it may be the result of mixing with water, which is commonly referred to as oil emulsification. At this point, the lubricant should be replaced.

If the sample is darkened or thickened, it may indicate that the lubricant has begun to carbonize and the old lubricant should be completely replaced. If possible, flush the oil line with fresh oil. When changing the lubricating oil, make sure that the new and old models of the replaced oil are the same and supplement the oil level that meets the requirements.

     The grease used in the one-way bearing must have an anti-rust effect, and the anti-rust agent is preferably insoluble in water. Grease should have good adhesion to form an oil film on the surface of the steel, even if the grease is filled with water. Grease becomes soft during machining and causes leakage. When there is a vibration application example, grease will be trapped inside the bearing by the IKO bearing housing. If the mechanical stability of the grease is insufficient, the grease will be continuously thrown out of the bearing, which will cause mechanical collapse of the soap structure and destruction of the grease.
