6306-2RS1/HC5C3GJN Bearing Product Overview & Core Advantages
The 6306-2RS1/HC5C3GJN is a sealed single row deep groove ball bearing engineered for superior performance in demanding applications. This metric bearing features a 30 mm bore and is constructed with advanced Silicon Nitride (Si3N4) ceramic balls, offering exceptional speed capabilities and extended service life. Its primary advantages include the ability to handle significant radial loads, excellent high-speed performance with a limiting speed of 9,600 rpm, and robust construction for reliable operation. The combination of ceramic balls and a C3 radial internal clearance makes it particularly suitable for applications requiring thermal stability and minimal friction.

6306-2RS1/HC5C3GJN Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The use of Silicon Nitride ceramic balls significantly reduces friction, heat generation, and wear, enabling higher operating speeds and longer service life compared to all-steel bearings. This makes it an ideal high-speed bearing solution.
Enhanced Sealing: The 2RS1 contact seals provide excellent protection against contaminants while retaining lubrication, ensuring reliable performance in harsh environments and contributing to maintenance-free operation.
Optimized Internal Clearance: The C3 radial clearance accommodates thermal expansion in applications with varying operational temperatures, preventing premature failure due to excessive preload.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures consistent performance and reliable operation in various industrial applications.
