Self-Aligning Ball Bearings
Self-aligning ball bearings have two rows of balls with a common sphered raceway in the outer ring. The bearing is consequently self-aligning and insensitive to misalignment of the shaft relative to the housing. It is particularly suitable for applications where misalignment can arise from errors in mounting or from shaft deflection.

The ultimate Self-aligning ball bearings guide
Self-aligning ball bearings are made up of two rows of balls, a commonly sphered raceway in the outer ring, and two deep uninterrupted raceway grooves in the inner ring. They are available in both open and sealed formats. The bearings are unaffected by angular misalignment of the shaft with respect to the housing.
What is a self-aligning ball bearing used for?
A self-aligning ball bearing is a type of ball bearing that is used in situations where the alignment of the shaft and housing is not perfect. The balls and cage of the bearing are free to rotate in the housing, which allows them to align themselves with the shaft. This type of bearing is often used in applications where the shaft is subject to misalignments, such as in pumps and motors.
Self-aligning ball bearings can accommodate misalignment of the shaft relative to the housing within certain limits, due to their spherical inner and outer raceways. This type of bearing is typically used in applications where the shaft is subject to misalignments, such as in pumps and motors.
The different types of self-aligning ball bearings
There are three main types of self-aligning ball bearings: the single row, the double row, and the four-point contact ball bearing. The single row is the most common type of bearing and can carry radial and thrust loads in both directions. The double row can carry radial and thrust loads in both directions but is not as common as the single row. The four-point contact ball bearing is not as common as the other two types but can carry radial loads in both directions.
The single-row self-aligning ball bearing has an inner and outer ring with a ball and cage assembly in between. The balls are made of steel and the cage is made of brass. The inner ring has two rows of balls and the outer ring has one row. The balls are separated by a metal shield that helps protect the bearings from contamination.
The double row self-aligning ball bearing has an inner ring with two rows of balls and an outer ring with one row. The balls are made of steel and the cage is made of brass. The inner ring has two rows of balls and the outer ring has one row. The balls are separated by a metal shield that helps protect the bearings from contamination.
The four-point contact ball bearing has an inner ring with four rows of balls and an outer ring with one row. The balls are made of steel and the cage is made of brass. The inner ring has four rows of balls and the outer ring has one row. The balls are separated by a metal shield that helps protect the bearings from contamination.
Self-aligning ball bearing advantages
There are many benefits to using self-aligning ball bearings. They are able to resist misalignment, which can occur due to shaft deflection or mounting errors. This type of bearing also has a lower friction rating, meaning that it requires less energy to operate. Self-aligning ball bearings are also able to accommodate heavy loads and high speeds.
Some of the disadvantages of self-aligning ball bearings include the fact that they are not as common as other types of bearings and that they are more expensive. In addition, this type of bearing is not as effective in applications where there is a high amount of vibration.
Self-aligning ball bearing disadvantages
There are a few disadvantages to self-aligning ball bearings. One is that they are not as durable as other types of bearings and can wear out quickly. Another is that they are not as precise, so they may not work as well in high-speed applications.
The third disadvantage is that they are more expensive than other types of bearings. Finally, self-aligning ball bearings are not as effective in applications where there is a high amount of vibration.
Self-aligning ball bearings applications
Self-aligning ball bearings are used in a wide variety of applications where there is a need for low friction and high performance. Some common applications include
Automotive applications
Self-aligning ball bearings are used in many automotive applications. One common application is in the suspension system, where they are used to support the weight of the vehicle and help keep the wheels in contact with the ground. Another common automotive application is in the transmission, where they are used to help transfer power from the engine to the wheels.
Aerospace applications
Self-aligning ball bearings are used in many aerospace applications. One common application is in aircraft engines, where they are used to help transfer power from the engine to the propeller. Another common aerospace application is in landing gear, where they are used to help support the weight of the aircraft during landing.
Industrial applications
Self-aligning ball bearings are used in many industrial applications. One common application is in pumps, where they are used to help transfer fluid from one location to another. Another common industrial application is in electric motors, where they are used to help transfer power from the motor to the equipment that it is powering.
