6902-2RS Thin Wall Ball Bearing Chrome Steel Rubber Sealed for Motors Home Appliances


Rubber seals, commonly referred to as rubber covers or shields, are critical components in bearings that provide protection against contaminants and retain lubrication. These seals are typically made from materials like nitrile rubber (NBR), fluoroelastomer (FKM), or silicone rubber, depending on the application requirements. 


Superior Contamination Protection:
Rubber seals effectively prevent dust, dirt, water, and other contaminants from entering the bearing, which helps maintain smooth operation and extends the bearing's lifespan.

Retention of Lubrication:
These seals keep the lubricant inside the bearing, reducing the need for frequent re-lubrication and minimizing maintenance requirements.

Enhanced Durability:
Rubber seals are resistant to wear and tear, making them suitable for applications with high rotational speeds or harsh operating conditions.

Chemical Resistance:
Depending on the material, rubber seals can resist oils, chemicals, and other corrosive substances, ensuring reliable performance in demanding environments.

Flexibility and Adaptability:
Rubber seals are flexible and can accommodate slight misalignments or deformations in the bearing assembly, providing a tight and secure fit.

Noise Reduction:
By preventing contaminants from entering the bearing, rubber seals help reduce noise and vibration during operation, contributing to smoother and quieter performance.

Cost-Effective Solution:
Rubber seals are relatively inexpensive compared to other sealing methods, offering a cost-effective way to enhance bearing performance and longevity.
