The Importance of Lubrication and Maintenance of FAG Spherical Bearings

The use of a variety of mechanical equipment for movable bearings and increasingly stringent market-required equipment and other attributes required by the bearings are increasingly diversified. In order to select suitable FAG bearings from a large number of structures and sizes, different angles are required. In the selection of bearings, generally thought that as a bearing, installation and removal of the difficulty of paving, bearing, size and outer spherical bearing market, etc. The space promised, the general decision bearing structure. In the use of a variety of mechanical design life and a variety of durable bearings limit the comparison of bearings, while determining the bearing size. In the selection of bearings, bearings tend to assume that the grease life that occurs in aging, fatigue life of the grease, wear resistance, and noise are also needed to be fully studied.

In the process of using FAG bearings, it is time to lubricate the external spherical bearings. Pay attention to the amount of grease used. If you use grease precisely, you must understand the grease in the bearing 6316-2RS movement to ensure the stability of the grease. The movement of the grease filled in the movable bearing can be roughly divided into two stages with the modification of the bearing.

Under the popular conditions, the grease filling capacity in FAG bearings always surpasses the practical requirement of direct participation in lubrication, and empties into the cavity of the rack and the bearing cover, and forms a contour on the periphery of the moving body. During this process, the bearing temperature quickly rises due to the excess grease resistance. Although most of the excess grease is squeezed out at the beginning of operation, the grease that squeezing on the raceway attachment may still be transferred and the moving body is brought into the raceway.

In the early stage of the operation of the outer spherical bearing, grease of the large part was quickly pushed out (less than one minute) and the accumulated grease was gradually discharged in a small amount after the grease was circulated along with the bearing transition. At this time, the bearing of Wenzhou is still inherited and increased until the excess grease is discharged. It can be called the lubricating grease's walking phase. According to the quality of the grease in the bearing structure, the filling amount and other factors, this time may last for more than ten minutes. , and even hours.

When applying grease to antifriction FAG bearings, it may not be necessary to use high pressure theory unless it is used with great care. High pressure can damage the bearings, spread the grease, and the danger of overheating with high temperatures poses an invisible environment near the FAG bearings. In most applications, ball or roller bearings can be fully lubricated if grease levels account for one-third to one-half of the spherical bearing capacity. Excess volume will usually be expelled by the seal case.

The anti-friction bearings in all FAG bearings basically consist of two hardened steel rings, multiple hardened balls or rollers, and a separator or cage that separates the rollers or rollers. These types are divided into many categories in use. Some types, such as needle-shaped column bearings, may not have an inner ring, and the rollers move directly on the hardened shaft.

Bearing inspection and determination: To determine whether it can be used to inspect bearing disassembly bearings after cleaning. Inspection of raceways, raceways, surface conditions, cage wear, ball bearing clearance and dimensional accuracy advances have been irrelevant to damage and anomalies. Non-separable small ball bearings, inner ring, with one hand's support level, rotating outer ring confirmed smoothly. A separate bearing, such as a bearing, can move the body and check the outer raceway surface. Large bearings, because they can not be rotated by hand, pay attention to check the track of the moving body, cages, walls, such as appearance, the importance of higher FAG bearings, to be more careful inspection.
