6306-2RSNR/C3 Bearing Product Overview & Core Advantages
The 6306-2RSNR/C3 is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its core advantages stem from a combination of a sealed design and a C3 radial internal clearance, making it exceptionally suited for applications with moderate speeds and thermal expansion considerations. The integrated snap ring on the outer ring simplifies axial location within the housing, reducing assembly time and cost. This bearing is designed to handle primarily radial loads efficiently while offering robust performance and long service life.
Model Code Breakdown
- 6306: Basic model number denoting a single row deep groove ball bearing with a 30mm bore and 72mm outside diameter.
- 2RS: Designates that the bearing is sealed on both sides with contact seals, providing effective protection against contaminants and retaining lubricant.
- NR: Indicates the presence of a snap ring groove on the outer ring, facilitating secure axial positioning.
- C3: Specifies a greater than normal radial internal clearance. This is beneficial for applications where thermal expansion or fit-induced clearance reduction is expected.
6306-2RSNR/C3 Bearing Structural Features & Performance Benefits
Robust Sealed Construction: The double-sided contact seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants, while also retaining the factory-preloaded grease. This design enhances bearing life in harsh environments.
Optimized Internal Clearance: The C3 clearance provides operational stability in applications where shaft and housing fits, or operational temperatures, may lead to a reduction in the original internal clearance, preventing premature failure due to excessive preload.
Simplified Assembly with Snap Ring: The outer ring snap ring groove allows for secure axial location without the need for complex housing shoulders or lock nuts, reducing design complexity and assembly time.
High-Quality Material: Manufactured from chrome steel for both rings and balls, ensuring high strength, durability, and resistance to wear.
