As the name suggests, these consist of two rows of balls. They are designed for applications requiring a higher load-carrying capacity. Further, the design allows these dozen-row variants to accommodate radial and axial loads coming from both directions. This property makes them ideal for use in construction machinery and other heavy-duty applications where reliability is of the essence.
QJ308-N2-HEGA bearing P6 with a split inner ring, inner ring 180 degrees apart
These are meant to handle heavy radial loads with additional axial load capacity in one direction. This variant's unique feature is the inner ring being split into two 90-degree segments. This feature facilitates use in situations where the space is limited or requires easy assembly. The design retains its effectiveness in high-load applications, thus making it perfect for use in mining equipment.
Four-point contact 7008 angular contact ball bearing P6
These are engineered to accommodate simultaneous loads in four directions. This design enables them to handle both axial and radial loads. It also makes provision for moments and supports dynamic loads. Multi-point contact bearings are, therefore, perfect for applications requiring high stability and precision. These applications include orbiting machinery and turntables.

Aerospace industry
In this space, these bearings are employed in aircraft components such as landing gear and engines. They ensure high reliability in this field. They also operate under extreme loads and varying speeds. In addition, their lightweight design and compact structure give them a very favorable risk-to-benefit ratio in the aerospace field.
Automotive industry
Here, the 7008 bearing is deployed in transmission systems, which require precision and durability under heavy loads. The bearing ensures smoothness in the operation of the motor and drive components. This factor contributes to the extended longevity of vehicles.
Energy sector
In this space, these bearings are utilized in wind turbines and power generation equipment. The bearings enable them to withstand radial and axial loads. Further, they provide enhanced energy efficiency and smooth operation.
Railway systems
In these systems, the P6 bearing is used to facilitate train wheel assemblies. They maintain stability and safety in this dynamic environment. The ability to handle high-speed and high-load conditions keeps the trains safe and reliable.
The 7008 angular contact ball bearing P6 is popular across many industries due to its unique features and parameters. The following are the bearing's key specs and features:
High precision
This bearing is designed and manufactured to have tight tolerances and smooth races. These factors contribute to enhanced operation and, thus, efficiency. It also minimizes vibrations and heat generation, leading to improved performance.
Durability and material
The 7008 angular contact ball bearing P6 is made from high-quality steel. This steel is heat-treated to ensure increased hardness and strength. Such treatment enhances the bearing's resistance to wear, fatigue, and deformation. These ensure it has a long operating life even under challenging conditions.
Optimal contact angle
The bearing has a contact angle of 30 degrees, ideal for combining axial and radial loads. This property allows the bearing to handle high axial loads while maintaining radial load capacity. This design feature contributes significantly to increased stability during tilting operations.
Ball and raceway design
The ball and raceway configuration is manufactured to promote the even distribution of loads across the bearing. It reduces stress concentrations and enhances the bearing's overall load-carrying capacity. This design is critical in providing reliable performance in high-demand scenarios.
Seals and shielding
To further enhance performance, this bearing P6 is equipped with either seals or shields, depending on the version required, namely the 7008 angular contact ball bearing. These seals/shields protect the bearing from contaminants such as dirt, dust, and moisture, which may adversely affect it. They also play a pivotal role in retaining lubrication within the bearing. This is critical in extending the bearing's lifespan and maintaining optimal functionality.
Lubrication
The bearing is pre-lubricated with high-quality grease. This ensures that even at the onset of its usage, there is minimal friction between its components. The grease has a good ability to resist being washed out, especially in challenging operating conditions. This factor ensures that the bearing sustains its smooth operation for an extended period.
Several factors come into play when selecting the proper 7008 angular contact ball bearing P6. Here are the most vital ones:
Load requirements
There are two load types in this context. They are axial and radial load types. These are the loads the bearing will need to endure in the person's application. In this case, one should ensure that the bearing's load capacity meets or surpasses the required load for their application. For instance, if an application subject's bearings to high axial loads, prioritizing bearings with a higher axial load capacity is preferable.
Speed rating
Bearings are usually used in high-speed applications like pumps and spindles. In these applications, it is advisable to ensure the selected bearing has a proper speed rating. This feature helps it prevent overheating and wear, thereby ensuring it has smooth operations throughout its lifespan.
Material and lubrication
Angular contact bearings are made from several materials. Each of these materials has unique properties. The most common materials are high-carbon chrome steel and ceramic composites. High-carbon steel is very durable and possesses high rigidity. On the other hand, ceramic composites are lighter and have better resistance to wear. Each of these materials comes with pros and cons for specific applications. One should consider operational environments and potential contaminants when selecting the material that best suits the user. Lubrication is key to bearing performance and longevity. Pre-lubricated bearings come in grease or oil. Grease-lubricated bearings offer better protection against contaminants. Oil-lubricated bearings, conversely, are suitable for high-speed applications.
Operating temperature
This bearing is ideal if the application involves extreme temperatures. It is because some bearings are designed to withstand high or low temperatures. These bearings remain effective under changing thermal conditions, so users should consider the operating temperature range in their application to retain the integrity of the bearing.
Sealing options
The 7008 angular contact ball bearing P6 has several sealing options. Each of these options protects it from contaminants. The options also help the bearing retain its lubrication. They include contact and non-contact seals. Contact seals offer higher protection levels but introduce some friction. This factor is only a disadvantage in specific applications. Conversely, non-contact seals reduce friction but offer moderate protection. One should select the appropriate sealing option depending on their operating environment to ensure the longevity of their bearing.
Yes, this bearing P6 can be used in applications involving both radial and axial loads. Its design allows it to handle the two load types simultaneously.
The contact angle determines how well the bearing can handle axial loads. The larger the angle, the better the bearing can handle axial loads. Thus, it makes this bearing ideal for heavy-duty applications.
Occasionally, users should check this bearing for signs of wear, contamination, or loss of lubrication. They should also ensure that the lubricants are replaced or replenished whenever necessary.
