6203-2ZNR Bearing Product Overview & Core Advantages
The 6203-2ZNR is a metric single row deep groove ball bearing engineered for exceptional performance in demanding applications. This shielded bearing features a snap ring groove on its outer ring, enabling secure axial location within a housing without complex machining. Its design is optimized to handle significant radial loads while offering reliable operation. The combination of chrome steel rings, a stainless steel cage, and pre-applied grease lubrication ensures high durability, long service life, and consistent performance, making it a robust and cost-effective solution for a wide range of industrial machinery.
6203-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 6203 | Standard single row deep groove ball bearing with 17mm bore, 40mm OD, and 12mm width. |
| Shield | 2Z | Bearing is fitted with non-contact shields on both sides. This provides effective protection against contaminant ingress while minimizing friction and allowing for higher limiting speeds compared to contact seals. |
| Snap Ring Groove | NR | The outer ring has a snap ring groove and is supplied with a snap ring. This feature simplifies assembly and provides secure axial location, reducing the need for complex housing shoulders or lock nuts. |
6203-2ZNR Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from high-grade chrome steel, the bearing components provide excellent resistance to wear and fatigue. With a dynamic load rating of 2237 lbf and a static load rating of 1068 lbf, it is capable of handling substantial radial loads in continuous operation.
- Optimized for Speed & Efficiency: The lightweight stainless steel cage ensures stable ball guidance and reduces centrifugal forces, contributing to a high limiting speed of 19,000 rpm. The non-contact 2Z shields add minimal friction, supporting efficient high-speed performance.
- Simplified Installation & Axial Security: The integrated snap ring groove (NR) is a key feature that allows for easy and secure mounting. It prevents axial displacement of the bearing in the housing, enhancing system reliability and simplifying design.
- Long-Term Reliability & Low Maintenance: The bearing is pre-lubricated with grease and sealed by shields on both sides, creating a protected environment. This design offers a maintenance-free solution for the majority of its service life and operates reliably within a temperature range of -30°C to 120°C.
