6210-ZNR Bearing Product Overview & Core Advantages
The 6210-ZNR is a single row deep groove ball bearing designed for high reliability and robust performance in demanding applications. A key distinguishing feature is its snap ring on the outer ring, which simplifies axial location within a housing, reducing design complexity and assembly time. This bearing is shielded (Z) and pre-lubricated with grease, offering effective protection against contaminants and providing long-term, maintenance-free operation. Engineered from high-grade chrome steel, it delivers an excellent balance of high radial load capacity and a limiting speed suitable for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6210 | Basic Bearing Number | Indicates a metric, single row deep groove ball bearing with a 50mm bore, 90mm OD, and 20mm width. |
| Z | Shield on One Side | Provides effective protection against large particulate contaminants. |
| NR | Snap Ring Groove | Specifies that the outer ring has a groove and is supplied with a snap ring for simplified axial location. |
6210-ZNR Bearing Structural Features & Performance Benefits
- Snap Ring for Simplified Assembly: The integrated snap ring eliminates the need for complex housing shoulders or lock nuts, reducing component count and assembly costs while ensuring secure axial positioning.
- Robust Load Capacity: Manufactured from high-quality chrome steel rings and balls, this bearing offers a high dynamic and static radial load rating, ensuring durability and long service life under significant loads.
- Contamination Protection & Maintenance-Free Operation: The non-contact steel shield (Z) protects the bearing interior from large particles. Combined with factory-applied grease lubrication, this design offers a sealed-for-life solution, ideal for applications where re-lubrication is difficult.
- Stable Performance & Precision: The stainless steel cage ensures smooth operation and guidance of the balls at high speeds. The standard CN radial internal clearance and P0 tolerance class provide consistent and reliable performance for most industrial applications.
6210-ZNR Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of applications where ease of assembly, space constraints, and reliable performance are critical. Key sectors include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
