6208 NR Bearing Product Overview & Core Advantages
The 6208 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 design and assembly. Manufactured with chrome steel rings and balls, and 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 standard CN radial internal clearance make it a versatile and cost-effective solution for general industrial use.
6208 NR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Standard bearing series designation, indicating a single row deep groove ball bearing with a 40mm bore and 80mm outside diameter. |
| NR | Specifies that the bearing is supplied with a snap ring (fitted) in a groove on the outer ring for axial location. |
6208 NR Bearing Structural Features & Performance Benefits
- Snap Ring for Secure Location: The integrated snap ring eliminates the need for a complex shoulder in the housing, reducing machining costs and ensuring the bearing remains correctly positioned, which is critical for maintaining performance and service life.
- High Radial Load Capacity: The deep groove raceway and robust construction enable the bearing to support high radial dynamic load ratings of 7306 lbf, making it suitable for applications with significant radial forces.
- Optimized for High-Speed Operation: The lightweight stainless steel cage minimizes centrifugal forces, contributing to a high limiting speed of 11,000 rpm, ensuring stable performance in high-velocity applications.
- Versatile & Durable Construction: Components made from chrome steel provide high hardness and wear resistance, while the open design allows for the application of various lubricants to suit specific operational needs.
