6008-2RS1NR/C3W64 Bearing Product Overview & Core Advantages
The 6008-2RS1NR/C3W64 is a sealed single row deep groove ball bearing engineered for high reliability and long service life in demanding industrial applications. This precision bearing features an integral snap ring groove on its outer ring for simplified axial location and is pre-lubricated with maintenance-free Solid Oil. Its design is optimized to handle significant radial loads while accommodating moderate axial loads in both directions. The combination of a C3 radial internal clearance and high-quality construction makes it exceptionally suitable for applications with thermal expansion or where precise shaft alignment is critical.
6008-2RS1NR/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 6008 | Standard metric series bearing with 40mm bore, 68mm OD, 15mm width | Defines core bearing dimensions for interchangeability |
| 2RS1 | Contact seals on both sides | Superior protection against contaminants and grease retention |
| NR | Snap ring groove on outer ring | Simplifies axial location and housing design |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits |
| W64 | Solid Oil (polymer matrix) lubrication | Maintenance-free operation, no grease leakage, long service life |
6008-2RS1NR/C3W64 Bearing Structural Features & Performance Benefits
Robust Sealed Design: The double-sided contact seals (2RS1) provide an effective barrier against contaminants while retaining lubrication, significantly extending bearing service life in harsh environments.
High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a dynamic load rating of 3754 lbf and a static load rating of 2585 lbf, ensuring reliable performance under substantial radial loads.
Simplified Assembly: The integrated snap ring groove (NR) eliminates the need for complex housing shoulders or separate retaining devices, reducing assembly time and cost.
Maintenance-Free Operation: Pre-lubricated with Solid Oil (W64), this bearing requires no re-lubrication throughout its service life, making it ideal for hard-to-reach or sealed-for-life applications.
Thermal Stability: The C3 radial clearance accommodates differential thermal expansion between the shaft and housing, preventing premature failure in applications with operating temperatures ranging from -30°C to 120°C.
