Schaeffler 0 Extra Light Series Ball Bearing, 20mm Inside Diameter, 42mm Outside Diameter - 3004-2RS


This ball bearing is designed for superior performance in electrical, mechanical, and automation applications. Measuring 20mm in inner diameter and 42mm in outer diameter, it features a double row angular contact design that enhances load-carrying capacity. Manufactured with both sides sealed, this bearing offers protection against contaminants, promoting longevity and reliability in demanding environments.

Features & Benefits


• Double row design enhances load distribution and stability
• Sealed on both sides to prevent ingress of contaminants
• Steel construction ensures durability and strength under load
• High load ratings of 9.4kN static and 14.3kN dynamic improve performance
• Polyamide cage reduces friction and noise during operation
• CN bearing clearance ensures optimal fit and movement

Applications


• High-load requiring compact design
• Rotating machinery in industrial environments
• needing effective sealing against solids and liquids

What is the significance of the double row design in enhancing performance?


The double row design allows for a greater load-carrying capacity and improved stability, which is beneficial in applications with dynamic forces or vibrations. This structure evenly distributes the load across more balls, reducing stress and prolonging bearing life.

What materials are used in the manufacturing of this bearing, and how does it affect performance?


This bearing is primarily made from steel, which provides exceptional strength and wear resistance. The polyamide cage further contributes to reduced friction and noise, ensuring smoother operation in various applications.

How does the sealing arrangement influence the bearing's lifespan?


The sealing arrangement on both sides prevents the entry of dirt and moisture, which can cause premature wear. This protection extends the bearing's operational lifespan, especially in harsh environments where contaminant exposure is likely.
