There are several types of rubber materials commonly used for bearing seals. Let’s explore some of them:

1. Nitrile Butadiene Rubber (NBR):

   • NBR is known for its excellent resistance to oils, fuels, and greases.
   • It is widely used in rubber seals, making it suitable for applications where exposure to lubricants is prevalent.

2. Silicone Rubber (VMQ):

   • Silicone rubber exhibits excellent temperature resistance, ranging from extreme cold to high heat.
   • It is commonly used in applications where temperature fluctuations are significant.

3. Fluoroelastomers (FKM):

   • FKM materials offer exceptional chemical resistance, making them suitable for aggressive environments.
   • They are commonly used in applications involving harsh chemicals and extreme temperatures.

4. Ethylene Propylene Diene Monomer (EPDM):

   • EPDM rubber is known for its excellent weather resistance and durability.
   • It is often used in outdoor applications, such as automotive weather seals and gaskets.

   Polyurethane (PU):

   • Polyurethane combines the properties of rubber and plastic.
   • It offers good abrasion resistance and can withstand heavy loads, making it suitable for dynamic sealing applications.

Remember that the choice of rubber material depends on the specific requirements of the application, including factors like temperature, chemical exposure, and load conditions. If you have a particular application in mind, feel free to contact us for more details!

Advantages

1. Sealing Function:

   • Rubber bearing seals are designed to create a barrier between the internal components of a bearing and the external environment.
   • The primary function is to seal the bearing, preventing contaminants (such as dust, dirt, and moisture) from entering.
   • The lip or sealing edge of the rubber seal makes direct contact with the shaft, ensuring an effective seal.

2. Isolation:

   • Rubber seals isolate the bearing components from external factors.
   • They prevent metal-to-metal contact, reducing wear and extending the bearing’s lifespan.

3. Vibration Damping:

   • These seals absorb vibrations and shocks.
   • By dampening vibrations, they contribute to noise reduction and overall system stability.

4. Weatherproofing:

   • Rubber bearing seals protect against weather elements such as rain, wind, and UV radiation.
   • They maintain the integrity of the bearing even in challenging environmental conditions.
