Four-point Angular Contact Ball BearingsQJF1021MB Bearing

Four-point Angular Contact Ball Bearings are a type of ball bearings that are designed to handle high radial and axial loads in both directions. These bearings feature four contact points between the inner and outer rings, providing increased rigidity and greater load capacity compared to other types of bearings.

With their unique design, four-point angular contact ball bearings are ideal for applications where space is limited and high precision is required. This type of bearing is commonly used in applications such as robotics, machine tools, and heavy machinery.

One of the key benefits of utilizing four-point angular contact ball bearings is their ability to handle both radial and axial loads simultaneously. This makes them an ideal choice for applications where both types of loads are present. Additionally, their enhanced load-bearing capacity allows for higher performance and longer lifespan, which results in lower maintenance costs and downtime.


Four-point angular contact ball bearings QJF1021MB are high precision bearings that are designed to handle radial and axial loads in both directions. These bearings have a unique design that allows them to bear axial loads from all four directions while providing good radial load capacity.

The structure of these bearings consists of an inner and outer ring with a set of four contact points at 35° angles between them. This design allows for higher speeds and reduced heat generation, making QJF1021MB bearings ideal for applications that require high precision and durability.

These bearings are made of high-quality steel with a durable cage made from either brass or steel. This construction provides stable operation even in harsh environments and under heavy loads. Additionally, the bearings feature a lubricant seal that prevents contamination from entering the inside of the bearing, further increasing durability and reliability.
