High Temperature Insulated Bearing
A high-temperature insulated bearing is a type of bearing designed to operate reliably in environments with elevated temperatures. These bearings are specially engineered to withstand thermal stresses, prevent electrical arcing, and maintain lubrication and performance at high temperatures. They are commonly used in applications such as electric motors, turbines, aerospace, and industrial machinery where standard bearings would fail due to heat.
Key features of high-temperature insulated bearings include:
- High-Temperature Materials: Made from heat-resistant steels, ceramics, or composite materials that can endure elevated temperatures without losing strength.
- Insulation: Incorporate insulating coatings or materials (such as polymer or ceramic coatings) to prevent electrical current passage that could cause damage.
- Lubrication: Use of high-temperature lubricants like solid lubricants or high-performance greases suitable for extreme heat.
- Design Considerations: Modified seals, cages, and clearances to accommodate thermal expansion and prevent contamination.
Common types:
- High-temperature ball bearings
- High-temperature roller bearings
- Insulated bearings with ceramic insulators or polymer coatings
Applications:
- Electric motors and generators
- Aerospace components
- Heat treatment equipment
- High-temperature industrial machinery
