6202 NR Bearing Product Overview & Core Advantages
The 6202 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding applications. Its key distinguishing feature is the snap ring (fitted) on the outer ring, which provides secure axial location within a housing, simplifying assembly and reducing overall design space. Manufactured from high-grade chrome steel with a stainless steel cage, this open-type bearing offers high precision, durability, and is suitable for a wide operating temperature range. Its P0 tolerance class and CN radial clearance ensure consistent performance for general industrial use.
6202 NR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6202 | Standard bearing series designation indicating metric dimensions: 15mm bore, 35mm OD, 11mm width. | Defines the core bearing dimensions and load capacity. |
| NR | Specifies that the bearing is supplied with a snap ring groove and a snap ring fitted on the outer ring. | Enables secure axial positioning, eliminating the need for a separate housing shoulder or complex locking devices. |
6202 NR Bearing Structural Features & Performance Benefits
Snap Ring Locating Feature: The integrated snap ring (outer ring locating feature) allows for a simplified and compact housing design. This feature provides positive axial location, preventing creep and simplifying maintenance.
High-Grade Material Construction: The combination of chrome steel rings and balls with a stainless steel cage ensures high strength, resistance to wear, and reliable operation, contributing to a long service life.
Optimized Load Capacity: As a single row deep groove ball bearing, it is primarily designed to support high radial dynamic load ratings (1812 lbf) while also accommodating moderate axial loads in both directions.
Standard Precision & Clearance: The P0 tolerance class and standard CN radial internal clearance make it a versatile and cost-effective choice for a wide array of general machinery applications, ensuring reliable performance without the need for ultra-high precision.
6202 NR Bearing Typical Application Areas
The 6202 NR bearing is ideally suited for applications requiring secure axial location and robust radial load support. Common uses include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems
- Agricultural Machinery
- Material Handling Equipment
