SKF angular contact ball bearing introduction free combination pairing
Arbitrary matching bearings are specially manufactured, so that when they are arranged and installed close together, a certain internal clearance or preload and/or uniform load distribution can be obtained without the use of gaskets or similar devices. Any pair of bearings has a model suffix to indicate internal clearance (CA, CB, CC) or preload (GA, GB, GC).

High-speed wire rod rolling mill bearings and their applications
In order to meet the increasing demand for construction steel, China's metallurgical industry has introduced dozens of high-speed wire rod production lines from abroad in recent years. The discharge port speed ranges from 63 to 100m/s, and the annual output is mostly 60×104-100× Between 104t. Due to the special nature of the high-speed wire mill, more stringent requirements are put forward for the matching bearings.
Lubrication and sealing of bearings for high-speed wire rod mills
Whether the working performance of rolling mill bearings can be effectively used depends to a large extent on the lubrication conditions. Lubricants are called "the fifth largest component of bearings".
Whether the working performance of rolling mill bearings can be used effectively depends to a great extent on the lubrication situation, and the lubricant is called "the fifth largest component of the bearing". More than 40% of the damage to rolling mill bearings is caused by poor lubrication. Therefore, to reduce the consumption of rolling mill bearings, it is necessary to select a lubrication method and high-quality lubricant suitable for the conditions of use, and to design and install a reliable installation to prevent the intrusion of foreign objects such as water and scale. Sealing means.
