6008 NR Bearing Product Overview & Core Advantages
The 6008 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable operation. 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 radial internal clearance (CN), this bearing offers a robust and cost-effective solution for a wide range of industrial applications requiring high reliability and simplified assembly.
6008 NR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6008 | Basic bearing designation indicating a metric, single row deep groove ball bearing with a 40mm bore, 68mm OD, and 15mm width. |
| NR | Specifies that the outer ring has a snap ring groove and is supplied with a snap ring fitted. This feature provides axial location. |
6008 NR Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Simplified Assembly: The integrated snap ring groove on the outer ring allows for secure axial location within the housing, eliminating the need for complex end caps or shoulders. This design reduces assembly time, cost, and overall system size.
- High Radial Load Capacity: The deep groove raceway and robust construction are optimized to handle significant radial loads, making it a reliable choice for power transmission and material handling applications.
- Precision and Reliability: Built to P0 tolerance class with a CN radial clearance, this bearing ensures consistent performance and smooth operation under standard operating conditions.
- Durable Material Construction: Components are manufactured from chrome steel for rings and balls, and a stainless steel cage, providing excellent durability and resistance to wear.
- Open Design for Lubrication Flexibility: The open (unsealed) design allows for the application of various lubricants (oil or grease) to suit specific speed and temperature requirements, with a recommended operating range of -30°C to 120°C.
