FR3zz Bearing Product Overview & Core Advantages
The FR3zz is a single row deep groove ball bearing designed for precision and reliability in compact applications. Engineered with inch dimensions, it provides robust radial load capacity and is optimized for high-speed operation. Its shielded construction and standardized internal clearance make it an ideal choice for applications demanding consistent performance and long service life without frequent maintenance.
FR3zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FR3 | Bearing series designation, indicating specific internal geometry and size. |
| zz | Signifies a non-contact shield on both sides. This provides effective protection against contamination while minimizing friction and heat generation, contributing to the bearing's high limiting speed. |
FR3zz Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: The deep groove raceway and complement of 7 precision chrome steel balls enable efficient radial load support and smooth operation.
- High-Speed Capability: The combination of a lightweight stainless steel cage, non-contact shields, and controlled internal clearance (MC3) allows for a high limiting speed of 43,000 rpm.
- Corrosion-Resistant Components: The 300 series stainless steel shields and cage enhance durability in challenging environments, extending the bearing's operational lifespan.
- Precision Manufacturing: Manufactured to ABEC1 tolerance class, this bearing ensures reliable and predictable performance for a wide range of industrial applications.
