Product Introduction

Self aligning ball bearings are very suitable for applications where the shaft and bearing seat are misaligned. Self aligning ball bearings are designed to adapt to three degree deviations and minimize friction and frictional heat. Due to the relatively small contact angle, the axial load capacity of these bearings is lower than that of angular contact bearings, etc.

Bearings can handle both static and dynamic misalignment. In addition, sealed self-aligning ball bearings can resist dust and other pollutants. Self aligning ball bearings have many applications, including mining, food processing, and large-scale production, such as in the textile industry.

*Construction of self-aligning ball bearings

The self-aligning ball bearing consists of an outer ring, an inner ring, a rolling element, a cage that accommodates the rolling element, and possible seals, which protect the rolling element and lubricant from contamination. Their design allows them to compensate for up to three degrees of misalignment between the shaft and housing components. The low friction inside the bearings will enable them to operate at higher speeds while generating much less heat than other bearings.

1. Outer ring

The outer ring of the bearing is a smooth spherical surface with no raceway. Due to the shape of the ring, the bearing can move slightly inside it, thereby adjusting for misalignment.

2. Inner circle

The inner ring of the self-aligning bearing consists of two raceways, which fix the ball and cage.

3. Rolling element and retainer

The retainer and inner ring fix the rolling elements of the self-aligning ball bearing in place. Due to the loose structure between the ball and the inner and outer rings, the friction force and frictional heat are both low. Usually, the cage is made of stamped steel, reinforced fiberglass, or machined brass.

4. Sealing

Self aligning sealed ball bearings can prevent dust and other pollutants from affecting rolling elements and lubricants. This greatly extends the service life of bearings, eliminates additional friction, and reduces maintenance costs and intervals.

*Advantages and disadvantages of self-aligning ball bearings

Ball bearings with self-aligning characteristics have many advantages compared to other types of bearings such as tapered bearings and deep groove ball bearings. However, the load-bearing capacity of self-aligning ball bearings is not as high as traditional ball bearings.

1. Advantages

(1) Misalignment

Self aligning ball bearings can offset up to

3 degree static and dynamic misalignment.

(2) Service life

Compared to other types of ball bearings, these bearings have high-speed performance and generate less heat and friction. This allows them to operate at lower temperatures and extend their lifespan while reducing maintenance.

(3) Light load performance

This type of bearing has low load requirements, which means they can perform well even under light loads.

(4) Low noise

Self aligning ball bearings generate low noise levels due to the loose fit between the rolling element and the outer ring. This makes them particularly suitable for household items such as fans.

2. Disadvantages

(1) Load type

The ball bearing on the self-aligning ball bearing is installed at a relatively straight angle between the inner and outer rings. This makes them suitable for handling radial loads rather than axial loads.

(2) Load capacity

Due to the small axial load contact point of the self-aligning ball bearing, it can withstand relatively small axial loads. If it is necessary to carry heavy loads, it is recommended to use self-aligning roller bearings with the same self-aligning characteristics.

3. Installation of self-aligning bearings

Tight sleeves are commonly used for installing self-aligning ball bearings.

To install these bearings correctly, please follow the following steps:

(1) Packaging with protective film can prevent external influences from interacting with components during transportation. Ensure to remove these films before installing the bearings.

(2) Apply engine oil or grease to the outer surface of the bearing.

(3) Use oil to lubricate the adapter.

(4) Slightly open the adapter and use the expander tool to slide it onto the shaft.

(5) After the adapter is in the correct position, place the bearing on the locking sleeve. To place the bearings in the correct position, if the shaft has threads, use nuts; If not, please use a bearing pusher kit or a small mallet.

(6) Ensure that the bearing can rotate on the outer ring after being in place. It should not be possible to rotate, but it should be possible to rotate freely.

(7) By removing the nut, placing the washer, and reinstalling the nut, lock the bearing in place with a locking washer.

Attention: If the locking sleeve is loose or not fully fixed in place, the inner ring of the locking sleeve will start to rotate. As a result, excessive friction may occur between these three components, leading to damage to the shaft, adapter, and bearings.

*Selection criteria for self-aligning bearings

The selection of self centering bearings is mainly based on the consideration of possible centering problems, as well as the application speed, load type, load size, tolerance, and bearing size.

1. Misalignment

Bearings with self-aligning ability are usually necessary.

When there may be misalignment of the shaft, self-aligning ball bearings are a good solution. Please remember that most self-aligning bearings can only handle misalignment of three degrees or less. Any deviation above this requires more customized bearings.

2. Speed

Compared to traditional bearings, self-aligning bearings can operate at higher speeds. For high-speed applications, self-aligning bearings are an excellent choice. However, lubrication and bearing size are also factors that affect speed. Therefore, it is also important to consider the speed, lubrication type, and load requirements of the machine. The operating speed of grease lubrication is slower than that of oil lubrication.

3. Load

Automatic self-aligning bearings are suitable for radial loads, but they are not suitable for axial loads due to their small contact angle. When choosing bearings, it is important to take this into consideration.

4. Sealing type and lubrication

If the bearings have open or shielded seals, lubrication procedures may be required. Otherwise, sealed bearings are usually pre lubricated.

5. Other

Select bearing size based on speed requirements, load type, load capacity, shaft size, and housing size.shaft size, and housing size.
