6210 NR Bearing Product Overview & Core Advantages
The 6210 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 groove on the outer ring, which simplifies axial location and reduces the need for complex housing designs. Manufactured with precision P0 tolerance and standard CN radial internal clearance, this bearing offers a robust and cost-effective solution for general industrial machinery requiring high rotational accuracy and ease of assembly.
6210 NR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6210 | Basic Bearing Designation | Indicates a single row deep groove ball bearing with a 50mm bore, 90mm OD, and 20mm width. |
| NR | Snap Ring Groove | Specifies that the outer ring has a groove for a snap ring, enabling secure axial positioning within the housing. |
6210 NR Bearing Structural Features & Performance Benefits
Simplified Axial Location: The snap ring groove is the defining structural feature, allowing for easy installation and secure retention, which minimizes assembly time and cost.
High Radial Load Capacity: As a deep groove ball bearing, it is optimized to carry significant radial loads, with a dynamic rating of 8340 lbf and a static rating of 5216 lbf.
Robust Construction: The bearing utilizes a stainless steel cage for durability and high-speed capability, complemented by chrome steel rings and balls for high strength and wear resistance.
Open Design & Versatility: The open (unsealed) design allows for versatile lubrication options, making it suitable for applications where the operating environment or specific performance requirements dictate a custom lubrication regime.
High-Speed Capability: With a limiting speed of 10,000 rpm, it is well-suited for a wide range of high-speed applications.
6210 NR Bearing Typical Application Areas
The 6210 NR bearing is ideally suited for applications where secure axial location and high radial load capacity are paramount. Common uses include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment
- Agricultural Machinery
- General machinery requiring a reliable, easy-to-install bearing with a snap ring for housing retention.
