6203-ZNR JEM Bearing Product Overview & Core Advantages
The 6203-ZNR JEM is a single row deep groove ball bearing designed for robust performance in radial load applications. Its key advantage lies in the integrated snap ring on the outer ring, which provides secure axial location within the housing, simplifying assembly and enhancing operational stability. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable precision for a wide range of industrial machinery, ensuring consistent performance and long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 17 mm bore, 40 mm OD, and 12 mm width. |
| -Z | Denotes a shielded bearing on one side, protecting the internal components from large contaminants while allowing for high-speed operation. |
| -NR | Indicates the outer ring is equipped with a snap ring groove and a fitted snap ring. This feature provides positive axial location, eliminating the need for complex housing shoulders and reducing assembly costs. |
| JEM | Manufacturer's designation, confirming the bearing's origin and quality standards. |
6203-ZNR JEM Bearing Structural Features & Performance Benefits
Deep Groove Geometry & High-Quality Materials: The optimized raceway and high-grade chrome steel construction for rings, balls, and cage deliver a high radial dynamic load rating of 2147 lbf and reliable operation under demanding conditions.
Snap Ring for Simplified Design: The integrated snap ring is a key structural feature that provides secure axial positioning. This allows for a more compact and cost-effective housing design, as it can replace the need for complex end caps or shoulders.
Shielded Protection: The single-sided shield (-Z suffix) effectively protects the bearing interior from large particulate contaminants, contributing to a longer service life and reduced maintenance in dirty environments.
Standard Precision & Clearance: Built to ABEC 1 (ISO P0) tolerance with a standard CN radial internal clearance, this bearing ensures smooth, low-vibration operation suitable for a vast majority of industrial applications.
