Hexagonal Boron Nitride (hBN) Bushings, Bearing Sleeves, and Insulating Bearings for High-Temperature and Vacuum Equipment

The Hexagonal Boron Nitride Bushings and specialized Composite BN part assemblies from Telite Ceramics are engineered for extreme vacuum environments. Our high-performance BN Bushings, Boron Nitride Bushings, and Bearing Sleeves provide superior self-lubrication and electrical insulation for advanced semiconductor CVD and PVD tools, even at temperatures up to $1800^{\circ}C$.

1. Features of Hexagonal Boron Nitride Bushings

Our Hexagonal Boron Nitride Bushings utilize a lamellar crystal structure that functions as a solid lubricant. As a leading manufacturer, Telite ensures each BN Bushings and Boron Nitride Bushings unit maintains its volume resistivity ($>10^{14}$ Ω·cm) in aggressive plasma environments. This Composite BN part reliability is critical for maintaining process purity in UHV (Ultra-High Vacuum) systems.

2. Composite Bearing Sleeves Performance (2025 Standard)

Utilizing our latest performance metrics, we provide specialized material grades for Bearing Sleeves that significantly outperform monolithic ceramics in mechanical load capacity:

3. Precision Machining for Boron Nitride Bushings

Telite utilizes multi-axis CNC diamond grinding to achieve tolerances of ±0.01mm for every Hexagonal Boron Nitride Bushings assembly. This precision is essential for BN Bushings and Bearing Sleeves used in rotating hardware, where contamination-free operation and chemical erosion resistance are paramount for high-yield semiconductor manufacturing.
