Design Features of NU 218 ECM/HC5C3 Bearing
NU 218 ECM/HC5C3 Bearing blends the robustness of steel with the superior properties of ceramic. NU 218 ECM/HC5C3 bore dia is 90 mm. Its out dia is 160 mm. NU 218 ECM/HC5C3 width is 30 mm. The inner ring and the outer ring are typically made of high-grade bearing steel. Its rollers are made of ceramic materials, most commonly silicon nitride (Si3N4). Ceramic rollers are lighter and harder than their steel counterparts.
What Benefits Can NU 218 ECM/HC5C3 Bearing Provide?
- High-Speed Capability: Ceramic rollers enable higher operational speeds with reduced centrifugal force.
- Wear Resistance: The hardness of ceramics extends bearing life by minimizing wear.
- Thermal Stability: Better temperature regulation due to lower thermal expansion of ceramic materials.
- Reduced Friction: Smoother ceramic surfaces lower friction, enhancing efficiency and reducing heat generation.
- Electrical Insulation: Non-conductive ceramics prevent electrical erosion in bearings.
- Corrosion Resistance: Suitable for chemically aggressive environments.
What Can NU 218 ECM/HC5C3 Bearing Be Used for?
NU 218 ECM/HC5C3 Bearing is ideal for applications requiring high performance under demanding conditions, such as:
- High-Speed Machinery: Perfect for machine tools and spindles due to its high-speed capability.
- Electric Motors and Generators: Its electrical insulation properties protect against electrical erosion.
- Aerospace Industry: Used for its reliability and thermal stability in varying conditions.
- Medical Equipment: Essential in high-precision devices like MRI and CT scanners for its low interference and high-speed operation.
- Automotive Industry: Suitable for high-performance and electric vehicles, offering efficiency and durability.
