HICERA NU209E Zirconia Cylindrical Roller Bearing: Engineered for Extreme Conditions

In the demanding world of precision machinery and CNC equipment, component failure is not an option. High temperatures, corrosion, and electrical currents can quickly degrade standard bearings, leading to costly downtime and maintenance. Enter the HICERA NU209E – a cylindrical roller bearing crafted from advanced zirconia (ZrO2) ceramic, representing a paradigm shift in bearing technology for severe-service applications.

Unmatched Material Superiority: Zirconia Ceramic

The core of the NU209E's exceptional performance lies in its material. Unlike traditional steel bearings, this unit is constructed entirely from zirconia (ZrO2). This engineering ceramic offers a formidable set of properties:

• Exceptional Corrosion Resistance: Immune to rust and resistant to most aggressive chemicals, making it ideal for wet, acidic, or caustic environments where steel would rapidly deteriorate.
• High-Temperature Prowess: Operates reliably at temperatures up to 800°C in standard atmospheres and an astonishing 1000°C in oxygen-free environments. For context, its silicon nitride counterpart can withstand even higher extremes.
• Electrical Insulation: Being a non-conductive ceramic, it prevents electrical arcing and pitting damage caused by stray currents, a common issue in electric motors and power generation equipment.
• Low Density & High Hardness: Reduces centrifugal forces for smoother operation and offers excellent wear resistance.

Robust Design for Critical Applications

As part of the proven NU series, the NU209E is designed as a floating bearing, perfectly suited for applications requiring axial displacement compensation, such as in long shafts susceptible to thermal expansion. When paired with an HJ retaining ring, it transforms into a locating bearing, capable of handling substantial unidirectional axial loads. The cageless (no retainer) design maximizes the number of rollers, significantly boosting its load-carrying capacity.

Performance Specifications You Can Rely On

The HICERA NU209E is built to handle significant stress within its operational parameters:

• Dynamic Load Rating: ~23 kN
• Static Load Rating: ~24 kN
• Speed Limit: 100 rpm (Note: Suitable for medium-speed applications; consult engineers for high-speed needs).
• Primary Industry: CNC Machinery & High-Precision Equipment

These ratings make it a robust choice for positioning tables, spindles, and other critical axes within automated systems.
