Unlocking Peak Performance in Harsh Environments: The HICERA NU209E Zirconia Hybrid Ceramic Bearing

In the demanding world of precision CNC machinery and high-temperature industrial applications, component failure is not an option. Introducing the HICERA NU209E Cylindrical Roller Hybrid Ceramic Bearing, engineered from advanced Zirconia (ZrO2) to deliver unparalleled reliability where standard steel bearings fall short. This bearing is a specialized solution sourced directly from the manufacturer, designed for the most challenging operational conditions.

Engineered for Extreme Conditions

The core of the NU209E's superior performance lies in its material composition. Fabricated entirely from Zirconia ceramic, this bearing offers a unique combination of properties essential for modern manufacturing:

• Exceptional Heat Resistance: Operates reliably at temperatures up to 800°C in standard atmospheres and an astounding 1000°C in inert, oxygen-free environments. This makes it perfect for furnaces, high-temperature processing equipment, and specialized machinery.
• Superior Corrosion Resistance: Immune to rust and highly resistant to a wide range of aggressive chemicals, acids, and alkalis, ensuring longevity in corrosive settings where metal components would rapidly degrade.
• Excellent Electrical Insulation: The non-conductive nature of zirconia prevents electrical arcing and pitting, protecting sensitive equipment from stray currents and electro-corrosion.
• Maintenance-Free Design: The cageless (no retainer) construction allows for a higher complement of rollers, increasing load capacity and eliminating a potential point of failure, especially under extreme thermal stress.

Robust Design and Key Specifications

As part of the standard NU series, the NU209E is designed for versatility and strength. Its cylindrical roller design is optimized for high radial load capacity.

• Load Ratings: Dynamic Load Capacity ~23 kN | Static Load Capacity ~24 kN.
• Speed Limitation: Recommended maximum operational speed of 100 rpm, suited for applications where high load and thermal stability are prioritized over ultra-high speed.
• Primary Application: Functions excellently as a floating bearing to accommodate axial displacement and thermal expansion within a shaft assembly. When paired with an HJ retaining ring, it can be used as a locating bearing to handle unidirectional axial loads.

Target Industries and Applications

The HICERA NU209E bearing is specifically tailored for advanced sectors where performance cannot be compromised:

Primary Industry: CNC Equipment – Including high-precision machining centers, grinding spindles, and other automated tools that generate heat or operate in clean/dry environments where lubrication is problematic.

Ideal For: Semiconductor manufacturing equipment, vacuum and inert atmosphere furnaces, medical and dental machining equipment, food processing machinery (where corrosion resistance is key), and any application involving magnetic fields or electrical insulation requirements.
