6304-2RS1N/C3 Bearing Product Overview & Core Advantages
The 6304-2RS1N/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This sealed bearing features a snap ring groove on its outer ring for secure axial location within a housing. Engineered with chrome steel components and manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent operation and long service life. Its key advantage lies in its ability to handle significant radial loads while the C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Basic bearing series, indicating a medium width deep groove ball bearing with 20mm bore, 52mm OD, and 15mm width |
| 2RS1 | Contact seals on both sides, providing superior protection against contamination |
| N | Snap ring groove on the outer ring for secure axial positioning |
| C3 | Greater than normal radial internal clearance, suitable for applications with thermal expansion or interference fits |
6304-2RS1N/C3 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient handling of radial loads and moderate axial loads in both directions, making it a versatile bearing solution.
Double Contact Seals (2RS1): These contact seals provide excellent protection against contaminants while retaining lubricant, significantly extending bearing service life in harsh environments.
Snap Ring Groove Design: The outer ring snap ring groove facilitates secure axial location, simplifying housing design and reducing assembly complexity.
C3 Internal Clearance: The greater radial clearance accommodates thermal expansion in applications with temperature variations and compensates for interference fits, preventing premature failure due to excessive preload.
Chrome Steel Construction: All critical components including rings, balls, and cage are manufactured from chrome steel, ensuring high strength, durability, and consistent performance under the specified temperature range of -30°C to 120°C.
