Open Double Angular Contact Ball Bearing Engineered for High Radial Stiffness and Heavy Load Durability in Manufacturing

Product Description:

The Double Angular Contact Ball Bearing is a highly versatile and robust bearing designed to meet the demanding requirements of various industrial applications. Known for its unique configuration, this bearing features a double row of angular contact balls, which enables it to accommodate both radial and axial loads simultaneously. This dual angular contact ball bearing design ensures superior rigidity and stability, making it an ideal choice for high-speed and precision machinery.

One of the key attributes of the Angular Contact Double Row Bearing is its double configuration, which consists of two rows of angular contact balls arranged in such a way that they can support axial loads in both directions. This allows for enhanced load-carrying capacity and better performance under combined load conditions compared to single row bearings. The dual angular contact ball bearing is particularly beneficial in applications where space constraints demand a compact solution without compromising on load handling capabilities.

The cage material used in Double Angular Contact Ball Bearings varies according to application needs and operating conditions. Common cage materials include steel, brass, and polyamide. Steel cages offer excellent strength and durability, making them suitable for heavy-duty applications. Brass cages provide good corrosion resistance and are often used in environments where contamination is a concern. Polyamide cages are lightweight and reduce friction, which is advantageous for high-speed applications where minimizing heat generation is critical.

Outer diameter dimensions of the Angular Contact Double Row Bearing vary depending on the bore size, providing flexibility to accommodate different shaft sizes and machinery requirements. This adaptability makes the bearing suitable for a wide range of equipment, ensuring compatibility with various design specifications. The ability to customize the outer diameter while maintaining the bearing’s performance characteristics is a significant advantage in engineering and manufacturing contexts.

Sealing types for these bearings include open, sealed, and shielded options. Open bearings allow for easier maintenance and are often used in clean environments where contamination is minimal. Sealed bearings are equipped with rubber or metal seals to prevent ingress of dirt, dust, and moisture, thus extending the bearing’s service life in harsh conditions. Shielded bearings feature metal shields that provide moderate protection against contaminants while allowing for higher-speed operation compared to sealed bearings. This versatility in sealing types ensures that the Angular Contact Double Row Bearing can be tailored to suit specific environmental and operational demands.

The application scope of the Double Angular Contact Ball Bearing is broad and diverse. It is widely used in machine tools, where precision and rigidity are paramount for accurate machining processes. In pumps, these bearings provide reliable support for rotating shafts, ensuring smooth and efficient operation. Gearboxes also benefit from the high load capacity and durability of dual angular contact ball bearings, which help in transmitting power effectively while minimizing wear and tear. Additionally, the automotive industry relies on these bearings for critical components that require high performance under variable load conditions, such as wheel hubs and transmission systems.

In summary, the Angular Contact Double Row Bearing is an essential component in modern mechanical systems, offering excellent load handling capabilities, durability, and adaptability. Its double configuration and diverse cage material options provide engineers with the flexibility to optimize performance for specific applications. The availability of multiple sealing types further enhances its suitability for a wide range of operating environments.
