Choosing Cylindrical Roller Bearings Cylindrical roller bearings are a common type of bearing. They are used for various applications, including power transmission, mining, metal recycling, oil production, and wind turbines. These bearings are available in both single and double-row designs. A common characteristic of cylindrical roller bearings is their high capacity for radial and axial loads. This makes them a good choice for heavy impact and radial loading. Depending on the design, these bearings can be mounted with a single flange or interference. Other designs, such as cageless, allow rings to move axially relative. There are several advantages to using cylindrical roller bearings. Besides their high load capacity, cylindrical roller bearings are also resistant to shocks and accelerations. This feature is essential in industrial machinery, as they have to withstand the high speeds and torques produced by motors, pumps, and gearboxes. In addition, the bearings can be machined thanks to their structure accurately. When choosing a cylindrical roller bearing, it is essential to determine the amount of radial and axial load the bearing will need to handle. Choosing suitable bearings can make a massive difference in the overall performance of a machine. On the other hand, using the wrong type of bearing could lead to reliability issues and damage to the bearing itself. If you have problems selecting a bearing, you can consult a vendor for information on the bearing's parameters. The bearing's size is another factor to consider. Bearings come in sizes ranging from 2mm to 50mm. However, the most crucial factor is the load. Depending on the application, you may need to choose a higher capacity for radial and axial loading bearings. For example, if the bearing handles a heavy radial load, it may be best to use a bearing with a high DN (diameter of the inner race) value. Bearings are manufactured with a range of materials and heat treatments. Some are case-hardened for more excellent durability, while others are pre-lubricated. Grease is commonly used for boundary lubrication, while oil is recommended for higher operating temperatures. Additionally, it is essential to determine the friction coefficient of the bearing. For the most part, cylindrical roller bearings are manufactured with low-carbon steels, though alloys can also be added to improve the bending fatigue of the bearing. Alloys ensure that the bearing combines a hard, rigid core and a hard case. While some cylindrical roller bearings are free-end, others are designed with a flange on the outer ring. Having an inner or outer ring with a rib can make the bearing more rigid, as this reduces the amount of friction. Cylindrical roller bearings are made with a cage, generally pressed steel. The cage can have fins, tins, or other features. To minimize the risk of contaminant exposure, the bearing is typically sealed. Sealing the bearings can help prevent contaminants from entering the bearing and contaminating the lubricant. Furthermore, a seal can prolong the bearing's service life.
