💡 Why choose a full ceramic bearing?
Full ceramic bearings are ideal for extreme environments - resistant to corrosion, heat, and electrical conductivity - perfect for high-tech, chemical, or underwater applications.

Excellent for cleanrooms, food processing, semiconductors, or high-speed spindles where steel and plastic won't hold up.

🔍 Comparison Table: 6900-2RS Full Ceramic vs. POM Plastic vs. Steel

🔧 Verdict:

• Go with Full Ceramic for demanding, non-conductive, or corrosive environments.

• Use POM Plastic when food-grade, chemical resistance, or moisture tolerance is needed with a budget-friendly material.

• Choose Steel when cost, strength, and all-purpose performance are your main concerns.
