The selection of bearings is determined based on the requirements of the load, service life, and operational reliability. Generally speaking, the lifespan of bearings is determined based on their basic rated load.
The dynamic load capacity of bearings is determined by the fatigue characteristics of the material; The bearing life refers to the time or total number of revolutions that a material experiences when it experiences fatigue. Therefore, the lifespan of bearings is related to the load, speed, and usage environment they bear.
The main function of the retainer in the Liduolu needle roller bearing is to ensure that the needle roller can guide the inner and outer track surfaces during operation, maintain the line contact state, and enable the needle roller to withstand large loads without damage. Therefore, maintaining the stability and consistency of the parallelism standards of each needle roller slot in the retainer plays a crucial role in the overall operational quality of the needle roller bearing.
Taiwan, China Liduolu FRB needle bearing 12 * 15 * 12. 3SDue to different usage environments, the materials used in the needle roller bearing retainer designed and produced by Liduolu can be divided into four types: low carbon steel, alloy steel, engineering plastics, and aluminum alloy. Generally speaking, bearings for high-speed engines should use retainers made of alloy steel or aluminum alloy; Low carbon steel or engineering plastic retainers can be used for gearboxes or bearings for medium and low speeds.
Although needle roller bearings are mainly targeted at commercial markets such as automobiles and industry, they are actually applied in various fields that use high-speed rotating equipment. The traditional approach is to coat the outer surface of the bearing cage with expensive copper and silver to reduce wear. However, in subsequent tests, it was found that the copper silver coating would still wear out when the bearing was operated at 9000 rpm for more than 100 hours, which not only damaged the cage, but could also cause premature damage to the bearing; After the same testing, the bearing cage of the bearing coated with VICOTE 804 Blk showed no signs of wear.
