6004-2ZN Bearing Product Overview & Core Advantages
The 6004-2ZN is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric precision bearing features shielded construction on both sides, providing effective protection against contamination. Engineered with chrome steel components, it delivers reliable operation and a long service life. Its key advantages include a high radial dynamic load rating of 2113 lbf, suitability for high-speed operation up to 17,000 rpm, and a compact design that saves space. The inclusion of a snap ring groove on the outer ring facilitates secure and simplified mounting, making it an ideal choice for applications requiring high reliability and ease of installation.

6004-2ZN Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for handling significant radial loads and moderate axial loads in both directions, offering versatile load capacity.
- Double Shields (2Z): Effectively retain lubricant and exclude larger particulate contaminants, enhancing bearing life in unclean environments without the added friction of contact seals.
- Snap Ring Groove (N): This feature on the outer ring allows for secure axial positioning within a housing, reducing assembly complexity and cost. It increases the rigidity of the overall assembly.
- Chrome Steel Construction: All critical components (rings, balls, cage) are made from chrome steel, ensuring high strength, durability, and consistent performance under load.
- Precision & Clearance: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, guaranteeing smooth and precise operation for a wide range of industrial applications.
