  4. Cage: The cage is a structure used to maintain the rolling elements in the correct position. It can be an annular metal or plastic component with grooves or spherical spacing to ensure even distribution between rolling elements, thereby reducing friction and wear.
  5. Seals: Some UCF210 bearings are also equipped with seals, which are made of rubber or metal and are used to prevent dust, dirt and liquid from entering the inside of the bearing. This helps increase bearing life and performance.

The construction and components of UCF210 bearings work together to support and rotate the shaft while reducing friction and wear, ensuring bearing reliability and performance. Each component plays an important role, and together they enable the bearing to operate efficiently in a variety of applications.

UCF210 bearing dimensions and specifications

The dimensional specifications of UCF210 bearings are one of the key factors in selecting and installing the bearings. The following are the dimensions of UCF210 bearings:

  • Inner diameter (d): The inner diameter of UCF210 bearing refers to the diameter of the bearing inner ring, expressed in millimeters (mm). The size of the inner diameter determines the diameter of the shaft that the bearing will fit.
  • Outer diameter (D): The outer diameter refers to the diameter of the outer ring of the bearing, expressed in millimeters (mm). The size of the outer diameter determines the dimensions of the outside of the bearing and therefore needs to be considered when selecting the mounting location.
  • Width (B): Width refers to the thickness or height of the bearing, also measured in millimeters (mm). The width dimension affects the overall thickness of the bearing and also needs to be considered during installation.
  • Threaded hole size: UCF210 bearings are installed on the base, and there will be threaded holes on the base for fixing the bearings. The size and type of threaded hole (e.g. imperial or metric threads) needs to match the bearing’s seat.

Correctly matching the inner and outer diameter dimensions of the bearing is closely related to the size of the shaft to be installed to ensure that the bearing can be securely mounted on the shaft and rotate smoothly. In addition, the size of the threaded holes in the base must also match the specifications of the bearing to ensure that the bearing can be securely fixed in the desired position.

When selecting a UCF210 bearing, be sure to carefully consider these dimensional specifications to ensure the bearing is matched to your specific application and installation needs. If the dimensions do not match, the bearing may not work properly or its safety performance may be reduced. Correct sizing is therefore critical to bearing performance and life.
