In this article, We willll explore the differences between metal and rubber (plastic) seals, focusing on O-rings as a representative example.
 

The Difference Between Metal and Rubber Seals for Bearings

 
Metal and rubber seals are two of the most common types of seals used in bearings. Metal seals are more durable and can withstand extreme temperatures, while rubber seals are more cost-effective and easier to install.
 

Metal Seals

 
Metal seals are made from a variety of materials, including steel, stainless steel, and bronze. They are typically used in applications where high temperature, pressure, or chemical resistance is required. Metal seals can be either static or dynamic. Static seals do not move, while dynamic seals move with the bearing.
 

Rubber Seals

 
Rubber seals are made from a variety of elastomers, including nitrile, neoprene, and silicone. They are typically used in applications where cost and ease of installation are more important than durability or temperature resistance. Rubber seals can be either static or dynamic. Static seals do not move, while dynamic seals move with the bearing.
 

Advantages of Metal Seals

  • - Durable
  • - Can withstand extreme temperatures
  • - Chemical resistant
  •  

Disadvantages of Metal Seals

  • - More expensive
  • - More difficult to install
  •  

Advantages of Rubber Seals

  • - Cost-effective
  • - Easy to install
  •  

Disadvantages of Rubber Seals

  • - Not as durable as metal seals
  • - Not as temperature resistant as metal seals
