Ideal for aerospace, semiconductor, and robotics applications, they offer 30% weight reduction vs. steel, enhancing energy efficiency and durability in extreme environments.

Precision-engineered from silicon nitride (Si₃N₄), these ceramic rollers are produced via Hot Isostatic Pressing (HIP), ensuring ultra-high density (≥99.5%) and minimal porosity. This process eliminates microcracks, yielding exceptional mechanical properties: hardness ≥1600 HV, fracture toughness ≥6 MPa·m¹/², and thermal stability up to 1300°C.

Certified to Schaeffler Group standards (ISO 3290, DIN 5401), they guarantee dimensional accuracy (ABEC 7/11 tolerances) and surface finish (Ra ≤0.005 μm). Additionally, they align with Google’s sustainability benchmarks, featuring low friction coefficients (μ ≤0.15), corrosion resistance, and compatibility with eco-friendly lubricants.

Ideal for high-speed, high-load applications—such as aerospace actuators, semiconductor conveyors, and precision gear systems—these rollers offer 30% weight reduction compared to steel, minimizing inertia and energy consumption. Their chemical inertness ensures durability in corrosive or oxidizing environments, while customizable sizes (⌀10 mm–⌀100 mm) and coatings (e.g., DLC) enhance versatility.

Combining HIP technology, rigorous certifications, and advanced design, these rollers deliver unmatched performance and longevity for modern engineering challenges.

Silicon nitride (Si₃N₄) full ceramic bearings are advanced mechanical components designed for extreme environments. Composed entirely of high-purity silicon nitride ceramic, including rings, rolling elements, and sometimes cages, these bearings exhibit exceptional hardness, corrosion resistance, and thermal stability (up to 1,200°C). Their low density reduces centrifugal forces, enabling high-speed operation, while their non-conductive nature eliminates electrical arcing risks. Silicon nitride’s self-lubricating properties minimize friction, extending service life in vacuum or high-temperature conditions. Ideal for aerospace, medical equipment, and precision machinery, they outperform steel bearings in wear resistance and longevity. Additionally, they resist chemical degradation and operate effectively without lubrication. Meeting ISO and ASTM standards, these bearings are critical for applications demanding reliability, lightweight design, and minimal maintenance.

Silicon Nitride (Si₃N₄) Hybrid Ceramic Bearings combine ceramic rolling elements (balls/rollers) with metal rings, offering superior performance in demanding applications. Key advantages include:

Material Properties: Si₃N₄ provides high hardness (15-16 GPa), low density (3.2 g/cm³), and corrosion resistance, reducing friction and wear.
Operational Benefits: Suitable for high-speed (e.g., machine tool spindles), high-temperature (up to 800°C), and electrically insulating environments.
Applications: Widely used in wind turbines, aerospace, and semiconductor manufacturing due to lightweight and durability.
Hybrid designs balance cost (metal rings) and performance (ceramic rolling elements), meeting ISO 26602 precision standards (G5-G10).
