Product Description

Key Features of Si3N4 Silicon Nitride Ceramic Insert Ball Bearing

(Custom configurations available upon request.)

Material Excellence:

Made from silicon nitride (Si3N4), a premium ceramic material known for its high strength, low density, and exceptional hardness.
Offers superior wear resistance and thermal stability compared to traditional steel bearings.
Self-Aligning Capability:

Insert bearings are designed with spherical outer surfaces, allowing for compensation of initial misalignments in housing installations.
Ensures smooth and reliable operation even under misalignment.
Lightweight Construction:

Si3N4 is approximately 60% lighter than steel, reducing the overall system weight and rotational inertia.
Improves efficiency and reduces energy consumption.
Corrosion Resistance:

Ceramic material is chemically inert, making it highly resistant to corrosion in harsh environments, including exposure to chemicals, moisture, and saltwater.
Low Friction and Smooth Operation:

Low friction coefficient minimizes heat generation and energy loss, ensuring efficient and quiet performance.
Thermal Stability:

Operates effectively across a wide temperature range, from cryogenic conditions to over 1000°C.
Low thermal expansion ensures dimensional stability and consistent performance under thermal cycling.
Electrical Insulation:

Non-conductive properties provide protection against electrical arcing, ideal for electric motors and generators.
Non-Magnetic Properties:

Non-magnetic nature eliminates interference in sensitive electronic equipment and magnetic field applications.
Pre-Lubricated or Maintenance-Free:

Many insert ball bearings come pre-lubricated, with some requiring little or no lubrication during their lifetime, depending on the application.
Durability and Longevity:

High fatigue resistance and wear resistance ensure a long operational life, reducing maintenance frequency and downtime.
Ease of Installation:

Typically designed for quick and simple installation into housing units, reducing assembly time and costs.
