NTN Domestic Double Row Angular Contact Ball Bearing, Inner Dia 20 mm, Outer Dia 52 mm, Width 22 mm, 5304 Series

A double row angular contact ball bearing is a specialized type of bearing designed to accommodate combined radial and axial loads in both directions. Unlike single row angular contact bearings, which have only one row of balls, double row angular contact ball bearings feature two rows of balls arranged at an angle to each other. This design enables the bearing to withstand higher radial and axial loads while maintaining high rotational speeds.

The inner and outer rings of a double row angular contact ball bearing are typically separable, allowing for easy mounting and dismounting. The contact angle between the balls and the raceways is optimized to distribute the load evenly across the bearing, reducing friction and wear.

These bearings are commonly used in applications where there are heavy radial and axial loads, such as in machine tools, industrial gearboxes, and automotive applications. Their ability to accommodate high loads and high speeds makes them ideal for demanding environments where precision and reliability are paramount.

Overall, double row angular contact ball bearings offer excellent performance, durability, and versatility, making them essential components in a wide range of machinery and equipment.
