6305-2RS1N/C3 Q66HT51 Bearing Product Overview & Core Advantages
The 6305-2RS1N/C3 Q66HT51 is a sealed single row deep groove ball bearing engineered for demanding industrial applications. This metric bearing features a 25 mm bore and is designed to primarily handle radial loads with high efficiency. Its key advantages include robust construction for reliable performance, a C3 radial internal clearance suitable for applications with thermal expansion, and sealed design for contaminant protection. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a dependable balance of precision and durability for general industrial use.
6305-2RS1N/C3 Q66HT51 Bearing Model Code Explained, Specifications & Naming Convention
- 6305: Basic series code denoting a medium-duty, single row deep groove ball bearing with a 25mm bore and 62mm outside diameter.
- 2RS1: Designates that the bearing is sealed on both sides with Nitrile Rubber (NBR) seals, providing effective protection against contaminants and retaining lubricant.
- N: Indicates the presence of a snap ring groove on the outer ring, enabling simplified axial location within a housing.
- C3: Specifies a greater than normal radial internal clearance. This is beneficial for applications where thermal expansion of the shaft and housing is expected, preventing excessive preload and potential bearing failure.
- Q66: A manufacturer-specific code often related to internal quality or process standards.
- HT51: A manufacturer-specific suffix, typically indicating a special heat treatment or material grade for enhanced performance.
6305-2RS1N/C3 Q66HT51 Bearing Structural Features & Performance Benefits
Robust Construction & Load Capacity: Built entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength and resistance to wear. It offers a dynamic load rating of 4631 lbf and a static load rating of 254 lbf, making it suitable for moderate to high radial load applications.
Sealed for Protection & Longevity: The double-sided rubber seals (2RS1) effectively shield the internal components from dust, dirt, and moisture, while also retaining any grease. This design enhances operational reliability and service life in contaminated environments.
Snap Ring Groove for Easy Assembly: The outer ring snap ring groove (N) simplifies axial positioning and securing of the bearing within a housing, potentially reducing the need for complex housing designs and lowering assembly costs.
Optimized Internal Clearance: The C3 clearance group accommodates fits and operating conditions where differential thermal expansion between the bearing and surrounding components occurs, ensuring stable performance under varying thermal conditions.
6305-2RS1N/C3 Q66HT51 Bearing Typical Application Areas
The 6305-2RS1N/C3 Q66HT51 is versatile and finds use across various sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Pumps and Compressors
- General machinery requiring a reliable, sealed deep groove ball bearing with a snap ring for secure mounting.
