Q

Q: What are the main applications of bearings?

A
1. Endurable bearings is a good choice for rolling machinery equipment used in smelters, mines and steel plants. 2. High-demand bearings suits for power equipment of power plants, gas turbines and motor factories. 3. Special bearings and outer spherical bearings is perfect for printing, packaging and food machinery,. 4.High temperature bearings allows for plastic, chemical fiber machinery and film stretching. 5. Miniature bearings applies in toys, watches, electronics, audio and video equipment. 6. Bearings are also used in agricultural machinery, spindle tools and food equipment.

Q

Q: How to maintain bearings and prolong service life?

A
1.Keep your bearings dirt-free, moisture free, and lubricated. Water will rust your bearings and dirt will destroy the smoothness of the super finish on your bearing races, increasing friction. 2.Clean your bearings when they become dirty or noisy with the most environmentally friendly cleaner you can find that is suitable for dissolving oil, grease, and removing dirt from the steel, plastic and rubber surfaces. We have tried many cleaners and solvents and many of them can be used safely. Citrus based cleaners can work, but they tend to leave behind a slight residue. Solvents are dangerous to use, but often provide a superior solution to cleaning very dirty bearings. If you use a water based cleaner like a citrus cleaner or a detergent, be sure to dry your bearings IMMEDIATELY and then re-coat them with lubricant to prevent rust. Some solvents/commercial products that we have used are: pure, or almost pure, isopropyl alcohol (The kind normally found in markets is only 10% pure and does not cut grease well.);
