6202-ZNR Bearing Product Overview & Core Advantages
The 6202-ZNR is a single row deep groove ball bearing designed for reliable performance in demanding applications. Engineered with precision to ABEC 1 standards, it excels at handling primarily radial loads. A key feature is its snap ring on the outer ring, which simplifies axial location and bearing mounting within a housing, contributing to a compact and secure assembly. Its shielded design offers effective protection against contamination, making it a robust and durable choice for a wide range of industrial machinery.
6202-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6202 | Standard designation for a single row deep groove ball bearing with a 15mm bore, 35mm OD, and 11mm width. | Defines the fundamental bearing dimensions and type. |
| Z | Denotes a shielded bearing on one side. | Protects the internal components from large contaminants like dust. |
| NR | Indicates the outer ring has a snap ring groove and is supplied with a snap ring. | Facilitates easy axial location and secure installation, saving space by eliminating the need for a complex housing shoulder. |
6202-ZNR Bearing Structural Features & Performance Benefits
Shielded Design: The inclusion of a non-contact shield on one side provides a high degree of protection against particulate ingress, enhancing bearing life and reliability in contaminated environments without significantly increasing rotational torque.
Snap Ring Locating Feature: The outer ring is machined with a groove and is supplied with a fitted snap ring. This design provides a positive axial location for the bearing within the housing, leading to a simplified assembly process and a more compact overall design.
Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a substantial dynamic load rating of 1812 lbf and a static load rating of 843 lbf, ensuring dependable performance under significant radial stresses.
Standard Precision & Clearance: Built to ABEC 1 (ISO P0) tolerance class with a standard (CN) radial internal clearance, this bearing provides a cost-effective balance of precision and performance for general industrial applications.
6202-ZNR Bearing Typical Application Areas
The 6202-ZNR is ideally suited for applications requiring secure mounting and protection from contamination. Common uses include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
