6305-2RS1NR/W64 Bearing Product Overview & Core Advantages
The 6305-2RS1NR/W64 is a sealed single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This precision bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include a snap ring groove on the outer ring for simplified axial location and secure mounting, combined with Solid Oil lubrication for long-term, maintenance-free operation. Designed with a CN radial internal clearance and manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and high reliability in a compact form factor.
6305-2RS1NR/W64 Bearing Model Code Explained, Specifications & Naming Convention
- 6305: Basic designation for a single row deep groove ball bearing with a 25mm bore and 62mm outside diameter.
- 2RS1: Indicates contact seals on both sides, providing superior protection against contamination.
- NR: Denotes a snap ring groove on the outer ring, facilitating axial positioning and simplifying housing design.
- W64: Specifies that the bearing is pre-lubricated with Solid Oil, a polymer-based lubricant offering excellent retention and long service life.
6305-2RS1NR/W64 Bearing Structural Features & Performance Benefits
The bearing's performance stems from its robust construction. The single row deep groove raceway is optimized for high-speed operation and efficient radial load carrying capacity. The contact seals (2RS1) effectively shield the internal components from dust and moisture, significantly extending bearing life. The inclusion of a snap ring groove (NR) enhances mounting rigidity and security, reducing the need for complex housing shoulders. The Solid Oil (W64) lubrication is permanently integrated, eliminating relubrication needs and preventing lubricant leakage, making it ideal for applications where maintenance is difficult. The CN radial internal clearance is the standard for general applications, ensuring optimal performance under normal operating conditions.
6305-2RS1NR/W64 Bearing Typical Application Areas
This versatile bearing is widely used across various industries due to its sealed and pre-lubricated design. Common applications include:
- Electric Motors and Gearboxes
- Material Handling Equipment such as conveyor systems
- Agricultural Machinery
- Industrial Fans and Blowers
- Food Processing and Packaging Machinery (where its sealed design is advantageous)
