Self-Aligning Ball Bearing

Manage alignment with our self-alignment ball bearing

Self-aligning ball bearings are recommended for applications where it is difficult to align the shaft and housing or where the shaft may bend, such as with transmission shafts. The outer ring has a circular raceway and its center of curvature coincides with the bearing, allowing the inner ring, ball and cage axis to rotate freely around the bearing center.

A pressed steel cage is commonly used for this type. Because they have a small contact angle, self-aligning ball bearings have a low axial load capacity. At our online store, you can buy self-aligning bearing online that are designed to prevent dynamic misalignment under normal load, which is approximately 0.07 to 0.12 radians (4 to 7 degrees);

Buy double row self-aligning ball bearings online for those angles which may not be acceptable depending on the surrounding structure. At Emechmart you can find the best self aligning bearing types that are used to give proper alignment to your industrial application.

Features of self-alignment ball bearings

If you consider buying self-alignment ball bearings online, you can consider these features to make an informed decision.

Adjust static and dynamic misalignment: Bearings are self-aligning such as spherical roller bearings or CARB bearings.

Excellent high-speed performance: Self-aligning ball bearings produce less friction than any other type of rolling bearing, enabling them to run cooler at higher speeds.

Minimal maintenance: Due to less heat generation, bearing temperatures are lower, which increases bearing life and maintenance intervals.

Less friction: A very loose structure between the ball and the outer ring keeps friction and frictional heat to a low level.

Excellent light load performance: Self-aligning ball bearings have lower minimum load requirements.

Low noise: Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.

Preventing mis-alignment with self-alignment ball bearing

Self-aligning ball bearings have a circular raceway in the outer ring with the center of curvature coinciding with the bearing center. This allows the inner ring, balls and cage to rotate freely around the bearing center, maintaining alignment. Thus, buy single row self-aligning ball bearing online, that with the smooth rotation of your industrial applications.

With our bearings, you can find that permissible dynamic misalignment is approximately 0.07 to 0.12 radians (4 to 7 degrees) under normal load. Self-aligning ball bearings are suitable for applications where the shaft turns and where it is difficult to align the shaft and housing (transmission shaft, etc.).

Application for self-alignment ball bearings

Here are examples of applications in which self-aligning ball bearings can be used:

·   Industrial fan

·   Agriculture

·   Care of goods

·   Food and drinks

·   Pulp and paper

Advantages of self-aligning ball bearings

A self-aligning ball bearing can tolerate shaft misalignment and deflection very easily with the help of its curved raceway, which is present on the outer ring. Farm equipment, transportation equipment, rudimentary woodworking machinery and ventilators are machines where you can find these bearings.

·   Excellent high speed performance

·   Low noise and vibration

·   Minimal maintenance

·   less friction

·   Adjust static and dynamic misalignment

·   Minimum load requirements

Buy Self-alignment roller bearings only from Emechmart

At Emechmart, you can easily buy two types of self-aligning bearings online by visiting and browsing our website. Two rows of rolling elements are supported in two raceway grooves in the inner ring of a self-aligning ball bearing, allowing the bearing to align itself. The raceway on the outer ring is curved. The cage consists of two rows of balls and an inner ring, which together form a single component that can be adjusted from side to side with the outer ring.
