When the bearing is running at high speed, the grease will be thrown out. What is the reason?
Some customers may ask, why is the grease inside the bearing thrown out during high-speed operation? Worried that if the grease is lost, the bearings will not be able to rotate, and will their lifespan be greatly reduced?
In fact, during high-speed operation, some excess grease will be directly thrown out, which has no protective effect on the bearings. On the contrary, excessive grease will increase in temperature during high-speed operation, which is not good for the service life. What works is only a layer of oil film in the channel, including a layer of oil film on the outside of the ball.
After the bearings are used up, you can take them apart to see. The ball was originally bright without grease, but after being coated with grease, the ball becomes matte with an oil film and feels sticky to the touch.
In fact, a small layer of oil film is used for lubrication. It does not mean that a large lump of oil needs to be rolled on this ball. This is the only way to provide lubrication. As long as there is an oil film on top of it, the bearing will run at high speed and be used with confidence.
