Unlocking the Power and Versatility of Flange Bearings: A Technical Insight into Key Parameters

As a core component in mechanical equipment, the technical parameters of  flanged bearing are like a precisely woven code, which deeply reveals their excellent load-bearing capacity and wide adaptability. These parameters are not only the crystallization of engineers' wisdom and experience, but also the key to ensure the excellent performance of bearings and meet the needs of various complex working conditions.

Inner diameter (d): As the diameter of the inner axis of the bearing, the size of the inner diameter is directly related to the size of the shaft that the bearing can adapt to. From tiny miniature flanged bearings of a few millimeters to large industrial-grade bearings of tens or even hundreds of millimeters, the diversity of inner diameters provides a wide range of compatibility for mechanical equipment of different specifications and different needs. This flexibility ensures that flanged bearings can be accurately embedded in various shaft systems to achieve efficient rotation and transmission.

Outer diameter (D): The outer diameter represents the overall external size of the bearing. It not only determines the installation space layout of the bearing in the mechanical equipment, but also directly relates to the bearing's load-bearing capacity. The outer diameter of large flanged bearings can reach hundreds of millimeters. Its wide support surface can disperse and carry huge loads, providing an indestructible guarantee for the stable operation of heavy equipment. This strong support capability makes flanged bearings widely used in heavy industries such as metallurgy, mining, and electricity.

Height (B): The height parameter, that is, the axial dimension of the bearing, not only affects the overall appearance and size ratio of the bearing, but is also closely related to its load-bearing capacity and operating stability. By optimizing the height design, the force distribution of the internal structure of the bearing can be reasonably adjusted to make it more balanced, thereby improving the bearing's load-bearing capacity and service life. Appropriate height can also effectively reduce the stress concentration caused by vibration and impact, and further improve the durability and reliability of the bearing.

Basic dynamic load (Cr) and basic static load (Cor): These two parameters are important scales for measuring the bearing's load-bearing capacity. The basic dynamic load (Cr) reflects the maximum load that the bearing can withstand under dynamic conditions (such as rotation, vibration, etc.); while the basic static load (Cor) represents the maximum load that the bearing can withstand under static or low-speed conditions. flanged bearings with high load capacity can ensure that mechanical equipment can still operate stably under extremely harsh conditions, such as heavy loads, impacts, vibrations and other complex environments. This strong load-bearing capacity makes flanged bearings widely used in high-demand fields such as aerospace, automobile manufacturing, and precision instruments.

Limiting speed: The limiting speed is the maximum speed at which the bearing can operate safely and stably. As modern mechanical equipment develops towards high speed and precision, higher and higher requirements are placed on the limiting speed of bearings. High-speed flanged bearings achieve higher limiting speeds and more stable operating performance by using advanced materials, optimized designs, and precise manufacturing processes. This high-speed characteristic makes flange bearings widely used in high-speed rotating equipment (such as generators, motors, centrifuges, etc.), providing reliable support for the efficient and stable operation of these equipment.
