Using the correct way to clean the bearing can effectively extend the life of the bearing

wallpapers Industry 2020-11-12
Generally speaking, most of the newly purchased bearings are coated with grease. But these greases do not play a role in lubrication, just to prevent the bearing rust. Bearings are generally difficult to clean up hidden dirt. Even newly purchased bearings without lubricating oil will absorb dust due to various reasons after a long time. Therefore, the correct cleaning of the bearing is very important. ERIC BEARING LIMITED is a professional distributor of famous brand bearings. We provide quality bearings at honest prices, if you need some kind of bearings, please contact us and we are glad to answer your questions and requests and will reply as soon as possible.


1. Preparation before disassembly
When disassembling the bearing for maintenance, first use a certain device to record the appearance of the complete bearing and confirm the residual amount of lubricant. After sampling the lubricant for inspection, the bearing is cleaned. The selected cleaning agent, generally speaking, the anti-rust oil-sealed on the bearing can be cleaned with a solvent-based cleaning agent. If there is a thick anti-rust oil on the bearing, you can use a solvent-based oil cleaner for metal parts first, dissolve it with appropriate heating, and take it out after the surface anti-rust grease is dissolved, and then wipe it.

2. Matters needing attention when cleaning
When cleaning, you should first pinch the inner ring of the bearing with one hand and slowly rotate the outer ring with the other hand until the oil on the rolling elements, raceways and cage of the bearing is completely washed off, and then clean the surface of the outer ring of the bearing. For bearings that are inconvenient to disassemble, wash them with a cleaning agent for parts to melt the old oil, and then use an iron hook or a small spoon to rinse off the remaining oil in the bearing. Be careful not to have an open flame when cleaning.
Do not rotate too hard at the beginning of the cleaning, otherwise, the raceways and rolling elements of the bearing are easy to be attached to dirt. They should rotate slowly and shake back and forth, which will have a better cleaning effect. When the number of bearing cleaning is large, it can be divided into two steps: coarse cleaning and fine cleaning. After it is roughly clean, switch to fine cleaning. Fine washing is to wash the bearing carefully while rotating it in the washing oil. When holding the bearing directly by hand, wash away the sweat from your hands and apply high-quality mineral oil before the operation. Pay special attention to rust prevention during the rainy season and summer.
