A bearing rubber seal is a flexible barrier made of rubber that attaches to the outer ring of a bearing to protect its internal components. It prevents contaminants such as dust, dirt and moisture from entering, and helps retain lubricants, thereby extending the service life of bearings and improving performance. Rubber seals are common in both ball and roller bearings, especially in applications where they are exposed to harsh environmental conditions.
Bearing rubber seals are extremely important in some bearings, which can protect the service life and work efficiency of bearings, so FTM will also customize the size, shape and thickness of bearing rubber seals according to the needs of bearings to ensure the use of bearings.
Design and function:
Rubber seals are usually installed on the outer ring and contact or form a tight fit with the inner ring to form a protective barrier.
The seal prevents outside contaminants from entering while retaining lubricants (such as grease or oil) within the bearing, thereby reducing friction and wear.
Materials:
Rubber seals can be made with oil resistant nitrile (NBR) or Viton (FKM), which is known for its high temperature and chemical resistance.
Types of rubber seals:
Contact seals: These seals are in direct contact with the inner ring of the bearing, providing a tighter seal and providing excellent protection, although they may increase slight friction.
Non-contact seals: These seals do not contact the inner ring directly, allowing for lower friction and higher speeds, but may not be as tight as contact seals.
Application program:
Commonly found in automotive parts, such as wheel bearings.
For agricultural machinery, conveyor systems, industrial equipment and power tools that operate in dusty, grime or wet environments.
Advantages of FTM bearing rubber seals:
Strengthen the protection of bearing components and extend the service life.
Reduce maintenance because the seal helps retain the lubricant in the bearing.
Versatility with different material options tailored to the specific environment, be it heat, chemicals, or humidity.
