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.


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.

Plug-in ball bearings mainly consist of the following parts:

Inner race: The part that mates with the shaft and usually has raceways to accommodate the balls.

Outer ring: The part that matches the bearing seat and also has a raceway.

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

Cage (optional): Used to maintain the distance between the balls and prevent them from contacting each other or coming off the raceway.

Locking collar: A device used to secure a bearing to a shaft, preventing the bearing from loosening during rotation.

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

Insert ball bearings are widely used in various mechanical equipment, especially where radial support and rotational motion are required. Here 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, transmission shafts, etc. often use plug-in ball bearings.

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

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

In other industrial fields: such as shipbuilding, electrical, textile, food processing and other industries, plug-in ball bearings are also widely used because of their excellent performance and wide range of applicability.

To sum up, the plug-in ball bearing is a 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.
