Customized 6816 Bearing Solution for Drive Wheel Reducer: Improved Heat Resistance and Load Capacity

2025-05-16

At Beining Technology, we specialize in providing customized bearing solutions that meet the unique needs of industrial applications. One example is our successful customization of the 6816 deep groove ball bearing used in drive wheel reducers.

The Challenge

In standard configuration, the 6816 ZZ bearing was equipped with steel shields and featured 27 steel balls. However, during operation in high-temperature environments, the bearing experienced oil leakage issues, which affected performance and durability.

Our Customization

To address this challenge, we proposed the following improvements:

Rubber Cover Replacement: Replaced the original steel shields cover (6816 ZZ) with two heat-resistant rubber seals (6816 2RS) to effectively prevent oil leakage under high temperatures.
Increased Steel Ball Count: Upgraded from 27 to 30 steel balls to enhance load distribution.
Raceway Curvature Optimization: Adjusted the raceway curvature to improve contact stress distribution and further increase load capacity.

Results

These modifications significantly improved the performance of the 6816 bearing in drive wheel reducers:

Better sealing performance in high-temperature conditions
Higher load-carrying capacity
Extended service life and enhanced operational stability

Conclusion

By tailoring the design of standard bearings to specific application requirements, we help customers achieve better reliability and efficiency. Whether it's sealing, material, or structural optimization, Beining Technology delivers customized bearing solutions that make a real difference.

If you're looking for customized bearings for your application, feel free to contact us and let us help you find the right solution.
