For sealed bearings, the production has been filled with the appropriate grease; to open bearings use also in the host is provided with the seal device, to prevent the leakage of lubricating grease.
There is a bearing lubricating grease to inject much better problem.
Filling grease amount is too small, easy to cause short fat or dry friction, impact of life. Filling grease amount is overmuch will lead to bearing temperature rise. Grease a large leak will pollute environment, and waste. Therefore, to the bearing grease is injected in to ensure sufficient lubrication of the bearing under the premise that less is more.
