In the process of using FAG bearings, especially when lubricating the bearings, pay attention to the amount of grease. If you use grease precisely, ask everyone to understand the movement of the grease in the bearing 6316-2RS to ensure the stability of the grease. The movement of the grease filled in the rolling bearing, followed by the modification of the FAG bearing, can be roughly divided into two stages.
The divergence of grease in the bearing is a divergence in the contours of the bearing. It must be composed of a relatively straight draft. It should be short-lived. The bearing temperature is low and stable during long-term operation. This is a more imaginative lubrication. Grease, so it is especially important for the grease.
In the popular situation, the amount of grease filled in the FAG bearing always surpasses the practical requirement of direct intervention lubrication, saturating the cavity on the frame and the bearing cover, and forming a contour on the periphery of the rolling element. During this process, the bearing temperature rises rapidly due to the resistance of excess grease. Although most of the excess grease is squeezed out at the beginning of the run, the grease that is squeezed into the raceway attachment may still be transferred to change the rolling element into the raceway.
In the early stages of bearing operation, most of the grease is squeezed out of the raceway very quickly (less than one minute), and accumulated in the grease retaining body after the bearing migration transition body, and is discharged a small amount. At this time, the bearing temperature will continue to rise until the excess grease is completely discharged. It can be called the grease's running phase. According to the grease quality and filling amount in the bearing structure, this time may last for ten minutes. And even hours.
When grease is added to anti-friction bearings, high pressure theory may not be required unless it is used with great care. High pressure can damage bearings and waste grease. Excessive grease can cause high temperatures and create an invisible environment around FAG bearings. In most applications, ball or roller bearings are fully lubricated if the grease level is between one-third and one-half of the bearing capacity. The excess will usually be wasted by the sealed casing.
The anti-friction bearings in all FAG bearings basically contain two hardened steel rings, a plurality of 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-like column bearings, may have no inner ring and the rollers move directly on the hardened shaft.
