Insert ball bearings, also known as radial insert ball bearings, are a specially designed ball bearing that is characterized by its installation and fixing method. Insert ball bearings are ball bearings that are fixed to the shaft or bearing seat by a specific method (such as locking rings, sealing washers, etc.). This type of bearing is usually easy to install and maintain, and is suitable for occasions that require radial support and rotational motion.


Features

Easy to install: Insert ball bearings are fixed to the shaft through accessories such as locking rings and sealing washers, without complicated installation steps, which improves installation efficiency.

Easy to maintain: Due to its special installation method, insert ball bearings can be easily disassembled and reinstalled when they need to be replaced or maintained.

Strong adaptability: This type of bearing is suitable for a variety of working conditions, including low speed, high speed, heavy load, and occasions where alternating direction rotation is required.

Sealing performance: Some insert ball bearings are equipped with sealing devices, such as P-type seals and R-type seals, to prevent foreign impurities and contaminants from entering the bearing and extend the service life of the bearing.


Insert ball bearings are mainly composed of the following parts:

Inner ring: The part that fits with the shaft, usually has a raceway to accommodate the balls.

Outer ring: The part that fits with the bearing seat, also has a raceway.

Balls: Rolling elements located between the inner and outer rings, which reduce friction by rolling.

Cage (optional): Used to keep the spacing between the balls to prevent them from contacting each other or leaving the raceway.

Lock ring: A device used to fix the bearing on the shaft to prevent the bearing from loosening during rotation.

Sealing gasket (optional): Used to enhance the sealing performance of the bearing and prevent foreign impurities and contaminants from entering.

Insert ball bearings are widely used in various mechanical equipment, especially in occasions that require radial support and rotational motion. The following are some specific application areas:

Mechanical equipment: Such as machine tools, CNC machine tools, presses, printing presses, etc., key components in these equipment such as spindles, drive shafts, etc. often use insert ball bearings.

Automotive field: Insert ball bearings also play an important role in key components such as automobile engines, transmission systems, steering systems, hydraulic systems, etc.

Aerospace: Due to the high precision, high reliability and long life requirements of the aerospace field, insert ball bearings are also often used in various systems of aircraft, rockets and other aircraft.

Other industrial fields: such as shipbuilding, electrical, textile, food processing and other industries, insert ball bearings are also widely used due to their excellent performance and wide applicability.

In summary, insert ball bearings are a type of ball bearing with the characteristics of convenient installation, easy maintenance, strong adaptability and good sealing performance. Its wide range of applications proves its importance in various mechanical equipment.
