How to maintain stability of imported FAG bearing grease - bearing knowledge

In the process of using FAG bearing, special for bearing lubrication, to pay more attention to the amount of grease. How accurately using grease and ask you must understand the grease in the bearing 6316 - In the 2 rs movement status to ensure the stability of the grease. Fill in the rolling bearing grease movement, follow the changes of FAG bearing, generally can be divided into two stages. Differences of grease in the bearing is divided sample outline of open to traffic, must constitute the outline is quite is, go should be short, bearing temperature in is running low, and smooth, this is a kind of more fantasy grease, so the lubricating grease into the canal of special priority. In popular conditions, FAG bearing grease filling amount, in always goes beyond the practice demand directly involved in the lubrication, full frame and bearing cover of the cavity, and an outline is made in the rolling around in vitro. In the process, because of excess grease resistance, bearing temperature rise quickly. Although most redundant grease at the beginning of the operation is being squeezed out, and squeezed in the raceway attachment grease could still be migration transformation between the rolling element into the race. Most of these in the early stages of the bearing running grease quickly ( Less than a minute) Is being squeezed out of raceway and accumulate in bao followed the bearing grease migration body cycle also, have a small amount of discharge. Bearing (degrees still continues to rise at this moment, until all redundant grease were discharge, may be called the grease running-in stage, according to the structure of the bearing grease, filling quantity elements such as quality, this paragraph of time may last ten minutes, and even a few hours. At the time of anti friction bearing filling grease, may not need to use the theory of high pressure, unless very careful to use. High pressure can damage the bearing, waste grease, excessive grease caused by high temperature dangerous and surrounding the FAG bearing invisible environment. In most applications, the ball or roller bearing lubrication, if grease level accounted for a third to a half of bearing capacity. Beyond the amount of usually will be sealed shell discharge and waste. All FAG bearing friction resistance of the bearing basically contains two hardened steel rings, multiple hardening of ball or roller, roller or roller and a separation or maintaining aircraft separation. These types are in use is divided into many types. Some types, such as bearings, needle column may not have the internal ring, roller directly on hardening axis movement.
