Product Description

Key Features of Hybrid Ceramic Roller Bearings (SS440C / Si3N4 / SS304)

(Custom configurations available upon request.)

Material Composition:

Rollers: Made of Si3N4 (Silicon Nitride), providing superior hardness, wear resistance, and lightweight construction compared to steel rollers.
Raceways: Typically SS440C (Martensitic Stainless Steel), offering high strength, corrosion resistance, and compatibility with ceramic rollers.
Cages: Often crafted from SS304 (Austenitic Stainless Steel), delivering excellent corrosion resistance and durability.
Lightweight and High Strength:

Ceramic rollers reduce overall bearing weight, enabling faster operation with lower energy consumption.
SS440C raceways and SS304 cages provide robust structural integrity and load-carrying capacity.
Corrosion Resistance:

SS440C and SS304 components offer excellent protection against corrosion, suitable for harsh environments including marine, chemical, and food processing applications.
Si3N4 rollers are chemically inert, further enhancing corrosion resistance.
Low Friction and High-Speed Capability:

Silicon nitride rollers generate less friction and heat compared to traditional steel rollers, enabling higher operational speeds and smoother performance.
Thermal Stability:

Si3N4 ceramic rollers maintain stability and performance over a wide temperature range, from cryogenic to elevated temperatures, without compromising bearing integrity.
Wear Resistance and Longevity:

Si3N4 is highly resistant to wear, deformation, and fatigue, extending the operational life of the bearing.
SS440C raceways support high loads while resisting abrasion.
Electrical Insulation:

The non-conductive nature of Si3N4 rollers prevents electrical arcing, making these bearings ideal for applications in electric motors and generators.
Non-Magnetic Properties:

Si3N4 ceramic rollers are non-magnetic, ensuring compatibility with sensitive applications like medical equipment and precision instruments.
Enhanced Heat Dissipation:

Ceramic rollers efficiently dissipate heat, preventing thermal damage during high-speed or high-load operation.
