604zz Bearing Product Overview & Core Advantages
The 604zz is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. As a metric bearing with shielded construction, it offers effective protection against contamination while maintaining low friction. Its compact design, featuring a 4 mm bore diameter and 12 mm outside diameter, makes it an ideal solution for applications with space constraints. This bearing is engineered to handle primarily radial loads and is characterized by its high limiting speed and consistent operation, providing a cost-effective solution for high-speed, precision mechanisms.
604zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| zz | Double-sided metal shields (non-contact) | Provides effective protection against dust and debris while minimizing friction and torque, contributing to the bearing's high-speed capability. |
604zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for handling radial loads efficiently. The deep groove geometry also allows for accommodating some axial loads in both directions.
- Shielded Construction (zz): The stainless steel shields help retain lubricant and exclude larger contaminants, enhancing bearing life and reliability in various environments.
- High-Speed Performance: The combination of a stainless steel cage, precision ABEC1 tolerances, and optimized internal geometry enables a limiting speed of 48,000 rpm.
- Precision Engineering: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring smooth and consistent operation.
- Material Quality: Components made from chrome steel (rings and balls) and stainless steel (cage and shields) offer excellent durability and corrosion resistance.
