Product Description

Key Features of Si3N4 Silicon Nitride Ceramic Ball Bearing

(Custom configurations available upon request.)

Exceptional Material Properties:

Made from silicon nitride (Si3N4), a high-performance ceramic known for its superior hardness, strength, and lightweight characteristics.
Provides excellent resistance to wear and corrosion, ensuring long-lasting performance.
High Hardness and Wear Resistance:

Significantly harder than steel, allowing the bearings to resist deformation and wear under high loads and speeds.
Lightweight Construction:

About 60% lighter than steel bearings, reducing rotational inertia and energy consumption in dynamic systems.
Enhances efficiency in high-speed and precision applications.
Thermal Stability:

Maintains structural integrity and operational performance in a wide temperature range, from cryogenic conditions to over 1000°C.
Low thermal expansion minimizes dimensional changes due to temperature fluctuations.
Corrosion Resistance:

Inert to most chemicals, including acids, alkalis, and seawater, making them suitable for corrosive environments.
High-Speed Capability:

Lightweight and low-friction design enables superior performance at high rotational speeds with reduced heat generation.
Suitable for ultra-high-speed applications, such as spindles in CNC machines.
Low Friction and Smooth Operation:

The low friction coefficient reduces energy loss, heat buildup, and operational noise, providing efficient and quiet performance.
Electrical Insulation:

Non-conductive material protects against electrical arcing, making it ideal for electric motors, generators, and applications requiring electrical insulation.
Non-Magnetic Properties:

Completely non-magnetic, preventing interference in sensitive electronic applications and equipment like MRI machines.
Durability and Longevity:

Excellent fatigue resistance and robustness against impact and vibration, even in demanding environments.
Extended operational life compared to traditional steel bearings.
