In the course of use of FAG bearings, especially when the bearing lubrication, pay attention to the quantity of grease. How to properly use lubricating grease, requires that we understand the grease in the bearings in the 6316-2RS movement to ensure the stability of lubricating grease. Fill in the movement of rolling bearing grease, FAG bearings rotation, generally can be divided into two phases.
Formed in the grease in the bearings of the different profiles is not the same as the opening, be sure to form the outline draft, exercise time is short, the bearing temperature is low in the long-term operation and smooth, it is otherwise a good grease, particularly important for lubricating grease into drains.
In normal circumstances, FAG bearings the grease fill volume, always exceeds the direct participation in the actual requirements of lubrication, fill cavities of frame and bearing cover and rolling the perimeter to form a profile. In this process, due to the resistance of excess grease, bearing temperature rise quickly. Although most of the excess grease in the early running was out, and squeezing roller attachment for grease also could still be turned between the rolling elements into the Raceway.
These bearing the initial phase of operation, most of the grease quickly (in less than a minute) crowding the Raceway, and piled up in the grease in the bearing rotor loop at the same time, one after another few to be discharged. Bearing temperature continues to rise until the excess grease is discharged so far, can be called a grease collection phase, based on factors such as quality, quantity of lubricating grease in the bearings, which can last a dozen minutes, or even hours.
After the remaining grease was completely discharged, leaving a small amount of grease in between rolling element and the Raceway, cage on the contact surface, film nationality wedge to form a thin layer of grease, thus entering the bearing normal phase. Temperatures gradually decline and reach equilibrium.
So concludes from the above: long-term lubrication, relies mainly on this layer grease film to bear. In addition, bearing long running process, as well as on the contour of the rolling element and the Raceway near cage grease on shrinking and ceding part of the base oil and into the Raceway after he, lubrication there is also a complementary role.
