Product Description:
Silicon nitride ceramic bearings are crafted with superior-quality
ceramics that exhibit exceptional performance characteristics.
Silicon Nitride Ceramic Bearings include high-temperature and
cold-resistance, wear-resistance, corrosion resistance,
anti-magnetic insulation, oil-free self-lubrication, and high-speed
capabilities.
Features:
Lightweight
Silicon nitride Ceramic Bearings is significantly lighter than
steel, which results in reduced rotational mass. This property
enables faster acceleration and higher efficiency.
High Hardness
Si₃N₄ Ceramic Bearings is an extremely hard material, which
ultimately leads to superior wear resistance and extended bearing
life.
High Strength and Toughness
Compared to other ceramics, silicon nitride exhibits excellent
fracture toughness, making it durable under heavy loads.
High-Temperature Resistance
Silicon nitride Ceramic Bearings can operate at temperatures
greater than 1,000°C without losing its mechanical integrity.
Corrosion Resistance
Silicon nitride Ceramic Bearings is chemically inert and resistant
to acids, bases, and oxidation, it can withstand even the harshest
environments.
Low Density
The density of silicon nitride Ceramic Bearings is about 40% that
of steel. This reduction in density results in lower centrifugal
forces at high speeds.
Performance Features
- Low Friction: This material provides smooth operation with reduced friction,
enhancing energy efficiency and reducing wear.
- Non-Magnetic: Silicon nitride Ceramic Bearings is suitable for applications
where magnetic interference must be avoided.
- Electrical Insulation: It acts as an electrical insulator, making it ideal for
applications requiring electrical isolation.
- Low Thermal Expansion: Minimal thermal expansion ensures dimensional stability across a
wide temperature range.
- High-Speed Capability: Silicon nitride Ceramic Bearings supports higher speeds due to low
density and reduced thermal effects.
