What are the reasons for the fracture of thin-walled bearing cages?

　In the thin-walled bearing cage rolling bearing, it plays the role of isolating the rolling elements at equal distances, preventing the rolling elements from falling off, and guiding and driving the rolling elements to rotate. Generally speaking, the thin-walled bearing cage will not be damaged under reasonable working conditions, but incorrect operations in daily production will reduce the service life of the thin-walled bearing cage. Common thin-walled bearing cage failure phenomena include: cage damage, loose or broken rivets, cage damage, and rolling element scattering. , Helvetica, Arial, sans-serif; font-size: 14px; text-wrap: wrap; background-color: rgb(255, 255, 255);">

　　If the lubrication work is not done well during the operation of thin-walled bearings, it will affect the normal operation. Therefore, ensure that there is enough lubricating oil for the bearings. If the lubricating oil is insufficient, the thin-walled bearing will be in a tilted state, which is more likely to cause bite wear, which will deteriorate the condition of the working surface and cause the tearing of the bite wear to enter the thin-walled bearing cage, causing abnormal cage load and possibly cage breakage.

　　When installing the thin-walled bearing retainer, there are problems such as improper installation, tilt, and excessive interference. It is easy to reduce the gap, intensify friction and heat during use, soften the surface, and cause premature abnormal peeling. As the peeling expands, the peeled foreign matter will enter the pocket of the thin-walled bearing cage, which will hinder the operation of the thin-walled bearing cage, generate additional loads, and increase the wear of the thin-walled bearing cage. This cycle of deterioration may cause the thin-walled bearing cage to rupture and be scrapped.

　　In fact, the most obvious reason for the fracture of thin-walled bearing cage is that foreign matter enters the thin-walled bearing cage, which will affect the operation of the cage, especially some hard foreign matter, which will aggravate the wear of the thin-walled bearing cage and generate abnormal additional load, which may cause the cage to break.

　　Creep is also one of the reasons for the fracture of thin-walled bearing cages. Creep refers to the sliding phenomenon of the ring. When the interference fit of the mating surface is insufficient, the load point moves toward the surrounding direction due to sliding, resulting in circumferential deviation of the ring relative to the shaft or housing. Once creep occurs, the mating surface wears significantly, and wear powder may enter the cross roller bearing, causing abnormal wear, raceway spalling, cage wear and additional load, and even cage fracture.

　　Thin-walled bearing cage quality issues also affect its use. If the quality is poor, it may break due to wear during use, especially when the thin-walled bearing cage is defective. Common defects include cracks, large foreign metal inclusions, shrinkage holes, bubbles or rivet defects, missing nails, padding nails or gaps between the mating surfaces of two thin-walled bearing cages, severe rivet damage, etc. All of these situations may cause the cage to rupture.
