Specifications of High Toughness Si3N4 Silicon Nitride Ball Full Ceramic Bearing

High Toughness Si3N4 Silicon Nitride Ball Full Ceramic Bearings are engineered for extreme performance in demanding environments. These bearings use silicon nitride (Si3N4) ceramic for both inner and outer rings and rolling elements. The material offers high toughness, excellent thermal stability, and resistance to wear and corrosion. They operate effectively in temperatures from -60°C to 800°C. This makes them suitable for applications where traditional steel bearings fail.

The bearings come in standard sizes ranging from 3mm to 50mm inner diameters. Custom sizes are available for specific needs. Precision grades meet ABEC 7 and ABEC 9 standards, ensuring minimal vibration and high rotational accuracy. Radial load capacities reach up to 12kN, axial load capacities up to 5kN. The full ceramic structure eliminates metal-to-metal contact, reducing friction and heat generation.

Silicon nitride’s non-conductive properties make these bearings ideal for electrically sensitive environments. They resist demagnetization, avoiding particle buildup in clean or vacuum settings. Lubrication is unnecessary due to ceramic’s self-lubricating traits. This reduces maintenance and prevents contamination in food processing or medical equipment.

These bearings excel in high-speed applications, supporting RPMs exceeding 300,000. Their lightweight design lowers centrifugal forces, enhancing efficiency in aerospace or automotive systems. They withstand harsh chemicals, acids, and alkalis, outperforming steel in corrosive industrial settings.

Common uses include turbochargers, dental drills, semiconductor manufacturing tools, and wind turbine systems. They are also applied in robotics, high-performance motors, and extreme-temperature machinery. The absence of lubrication requirements extends service life in dry or high-vacuum conditions.

Full ceramic bearings reduce energy loss by up to 30% compared to steel alternatives. Their hardness (HV 1600-1800) ensures minimal deformation under heavy loads. Advanced manufacturing techniques guarantee uniform density and surface finishes below 0.02μm Ra. This precision minimizes noise and vibration during operation.

High Toughness Si3N4 Bearings are tested for reliability under continuous stress. They meet ISO 26602 standards for material quality and dimensional accuracy. Custom configurations include shielded or sealed designs for added protection. These bearings are a durable, low-maintenance solution for industries prioritizing precision and longevity.
