Types of ball bearings
There are several types of ball bearings commonly used in mechanical applications:
1. Deep Groove Ball Bearings: These bearings have a deep, uninterrupted raceway groove that enables them to accommodate radial and axial loads in both directions. They are versatile and suitable for a wide range of applications, including automotive, industrial machinery, and appliances.
2. Self-Aligning Ball Bearings: Self-aligning ball bearings have two rows of balls and a spherical outer raceway, allowing them to accommodate misalignment between the shaft and housing. They are ideal for applications where shaft deflection or misalignment may occur, such as in conveyor systems and agricultural machinery.
3. Angular Contact Ball Bearings: Angular contact ball bearings are designed to support both radial and axial loads by handling higher axial loads than deep groove ball bearings. They have raceways inclined at an angle to the bearing axis, allowing them to carry combined radial and axial loads.
4. Miniature and Instrument Ball Bearings: These bearings are small in size and typically used in precision instruments, electric motors, and hobby applications. They come in various configurations, including open, shielded, and sealed designs.
5. Thrust Ball Bearings: Thrust ball bearings are designed to support axial loads in one direction and consist of two washers with a series of balls sandwiched between them. They are commonly used in applications requiring high axial load capacity, such as automotive transmissions and steering systems.
6. Four-Point Contact Ball Bearings: Four-point contact ball bearings have a unique design with a single row of balls and four points of contact with the raceways. They can support radial, axial, and moment loads simultaneously and are commonly used in crane swivels, excavators, and robotics.
These are just a few examples of the types of ball bearings available, each with its own design characteristics and advantages suited for specific applications and operating conditions.
