Design and Structural Features

Dual Row Balls and Sphered Raceway: Self Aligning Ball Bearings have two ball rows and a spherical outer raceway, enabling the inner ring, balls, and cage to pivot for self-alignment. The design aligns the bearing center with the raceway's curvature for free rotation of the inner components.
Inner Ring Grooves and Bearing Materials: Constructed with deep uninterrupted raceway grooves in the inner ring for enhanced stability, available in standard rolling bearing steel and stainless steel variants for different application needs.

Advantages of Self Aligning Ball Bearings

Self aligning ball bearings provide the following advantages:

Adaptive Misalignment: Capable of adjusting to angular misalignments typically between 4 to 7 degrees, suitable for both static and dynamic misalignment scenarios.
High-Speed Efficiency: Exhibits lower friction compared to other bearing types, ensuring cooler operation even at higher speeds.
Durability & Low Maintenance: The low friction design contributes to reduced heat generation, thereby extending bearing lifespan and minimizing maintenance needs.
Optimized for Light Loads: Efficiently handles light loads due to its precise alignment capabilities.
Noise and Vibration Reduction: The bearings' ability to maintain alignment reduces noise and vibration, making them ideal for fan applications and similar uses.

Cage Design and Sealing Options

Commonly, pressed steel cages are used, contributing to the bearing's overall functionality.
Available in both open and sealed variants, with sealed bearings offering enhanced protection against contamination and requiring minimal maintenance. Sealed self aligning ball bearings are lubricated for life with high-quality greases suitable for various operating conditions.

Applications of Self Aligning Ball Bearings

Self Aligning Ball Bearings are versatile and find applications in a wide range of industries. They are particularly beneficial in scenarios such as:

Transmission Shafts: Where shaft bending is a common occurrence.
Gearboxes and Speed Reducers: Providing reliable performance in complex mechanical systems.
General Machinery: Where misalignment issues might arise due to mounting errors or operational conditions.
