Description

ABOUT OUR PRODUCTS 1. Chromium Steel (GCr15) races offer high hardness and great wear resistance, low noise, and long service life. 2. Single-row, pre-lubricated, these bearing mainly used to accommodate radial loads. 3. Suitable for all kinds of industrial equipment, small rotary motor, office equipment, toys, and power tools, lawnmower, tractor, etc. 4. We have various types of bearings with different sizes, you can purchase according to actual needs. Read more 1. How to tell if the bearings need lubrication or not? - Lubricating is based on working conditions. - If the following conditions happened: the bearings have abnormal noise, the grease deteriorated, or the friction increased, it is recommended to replace the grease or lubricant. - If the lubricant is performing that service well, there should be no need to change it or add more. 2. Typical Lubrication Amount - Bearing lubrication plays a vital role. The most important role of lubricant is to reduce friction. - The internal space in the bearing was completely filled with grease means 100% full, typically lubrication range from 20% to 40%. In small or miniature bearings grease fill amounts can be as little as 10%. - Too much grease raises the temperature inside the bearing, excess heat could decrease the effectiveness of the lubricant. 3. Notice - Adding too much, or not enough grease both lead to the bearing failing prematurely. - Before operating at full speed, a running-in period is required to allow the grease time to settle into the housing cavity.
