6306-2RSNR/C3 VT228 Bearing Product Overview & Core Advantages
The 6306-2RSNR/C3 VT228 is a single row deep groove ball bearing engineered for high-performance industrial applications. This precision bearing is distinguished by its sealed design and snap ring feature, providing exceptional reliability and simplified mounting. Its optimized internal geometry enables it to handle significant radial loads while accommodating moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, it delivers consistent performance in applications with thermal expansion or demanding operating conditions, making it an ideal choice for robust machinery requiring long service life.
6306-2RSNR/C3 VT228 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6306 | Standard bearing series designation (30mm bore, 72mm OD, 19mm width) | Defines core bearing dimensions for interchangeability |
| -2RS | Contact rubber seals on both sides | Provides superior contamination protection and grease retention |
| NR | Snap ring groove on outer ring | Enables axial location and simplified housing design |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, ideal for high-temperature applications |
| VT228 | Manufacturer's specific designation (may indicate special features or lubrication) | Consult manufacturer for specific performance characteristics |
6306-2RSNR/C3 VT228 Bearing Structural Features & Performance Benefits
Sealed Construction: The double-sided contact seals (2RS) provide excellent protection against contaminants while effectively retaining lubricant, significantly extending bearing service life in harsh environments.
High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing achieves a dynamic load rating of 6002 lbf and static load rating of 3372 lbf, ensuring reliable operation under substantial radial loads.
Axial Location Feature: The snap ring groove (NR) on the outer ring allows for secure axial positioning within the housing, simplifying assembly and reducing the need for complex housing designs.
Optimized Internal Clearance: The C3 radial clearance provides additional internal space to accommodate shaft expansion under operational heat or interference fits, preventing premature failure due to excessive preload.
Wide Temperature Range: With an operational temperature range from -30°C to 120°C, this bearing maintains performance across diverse industrial environments.
