Maximizing the Service Life of Bearings
Source: Bearing Network | Date: December 9, 2013
Choosing the right bearing is essential for maximizing its service life. Several factors must be considered during selection, such as load capacity, material hardness, and operating environment. A well-chosen bearing can significantly increase its operational lifespan. Proper storage is equally important. Bearings should remain in their original packaging until they are ready to be installed. They should be stored in a clean, dry, and temperature-controlled environment. Avoid exposure to dust, moisture, and corrosive chemicals. Additionally, avoid unnecessary vibration or impact, as these can damage the internal structure of the bearing. Most bearings should be stored horizontally, while heavier ones may be stored vertically. However, improper vertical storage can cause deformation due to their own weight. Greased or sealed bearings require special attention, as the grease may change consistency over time. When first used, this can lead to initial noise or reduced performance. Therefore, it's important to follow a first-in, first-out (FIFO) system to ensure proper usage. Maintaining cleanliness is crucial for rolling bearings. The raceway surfaces are extremely smooth, and even small particles can cause damage. These contaminants can become trapped between rolling elements, leading to increased friction and potential failure. Regular cleaning and inspection help prevent such issues. When installing or removing bearings, always use the correct tools and techniques. Improper installation is a common cause of early bearing failure, with studies showing that up to 16% of failures are due to incorrect handling. Refer to manufacturer guidelines, manuals, and instructional videos for proper procedures. Always handle components carefully to avoid damaging surrounding parts. Avoid applying force directly to the rolling elements during installation or removal. This can cause localized stress and premature wear. Never use hammers or other hard objects to strike the bearing, as this can crack or break the inner or outer rings. Instead, use appropriate press tools or hydraulic devices. Lubrication plays a vital role in extending bearing life. Proper lubricants reduce friction, protect metal surfaces, and prevent contamination. Different applications require different types of lubricants, so it's important to select the right one based on operating conditions.
