The Same Batch Of Non-standard Bearing Of The Same Size, Used Under The Same Working Conditions

Non-standard bearing sealing can be divided into two types: self-sealing and external sealing. The so-called Non-standard bearing with its own seal is to make the Non-standard bearing itself into a device with sealing performance. Such as Non-standard bearing with dust cover, sealing ring, etc. This kind of seal occupies a small space, is convenient to install and disassemble, and the cost is relatively low.

Due to the manufacturing precision, the uniformity of the non-standard bearing material is different, even if it is the same material, the same batch of Non-standard bearing of the same size, used under the same working conditions, its life span is different. If the statistical life is 1 unit, the longest relative life is 4 units, the shortest is 0.1-0.2 units, and the ratio of the longest to the shortest life is 20-40 times. 90% of the non-standard bearing does not produce pitting corrosion, the number of revolutions or hours experienced is called the rated life of the non-standard bearing.
