What are the Benefits of choosing HCB7222-E-T-P4S bearings?
1. Ultra-high speed: The low density of ceramic balls (approximately 40% of steel balls) results in low centrifugal force, significantly increasing the maximum speed.
2. Long lifespan: High hardness and low coefficient of friction lead to minimal wear; the material itself is corrosion-resistant, high-temperature resistant, and has a long fatigue life.
3. Low heat generation: Good self-lubricating properties result in low temperature rise during operation and excellent thermal stability.
4. High rigidity: High elastic modulus (approximately 1.5 times that of steel) provides strong resistance to deformation and more stable machining accuracy.
5. Insulation: Excellent electrical insulation properties (high resistivity) prevent electrolytic corrosion damage, making it suitable for applications such as motors.
6. Low maintenance: Low lubrication requirements ensure high long-term operational reliability and reduce downtime for maintenance.
