6410 NR Bearing Product Overview & Core Advantages
The 6410 NR is a single row deep groove ball bearing designed for robust performance in demanding applications. Its primary characteristic is the snap ring groove and fitted snap ring on the outer ring, which provides secure axial location within a housing, simplifying assembly and reducing the need for complex housing designs. Manufactured from high-grade chrome steel with a stainless steel cage, this bearing offers a high radial dynamic load rating of 19,581 lbf and is capable of high limiting speeds up to 7,500 rpm. Its open design allows for versatile lubrication options, making it a versatile and reliable choice for a wide range of industrial machinery.
6410 NR Bearing Model Code Explained, Specifications & Naming Convention
The model number 6410 NR can be broken down as follows:
- 6410: The basic bearing designation, indicating a metric single row deep groove ball bearing with a 50 mm bore, 130 mm outside diameter, and 31 mm width.
- NR: This suffix denotes that the bearing is equipped with a snap ring groove and a snap ring is fitted to the outer ring. This feature aids in axial location.
Key specifications derived from the model and its standard design include a P0 tolerance class (Normal) and CN radial internal clearance (Normal).
6410 NR Bearing Structural Features & Performance Benefits
The 6410 NR's performance stems from its specific construction features:
- Snap Ring Location: The integrated snap ring provides a positive axial location, preventing creep and simplifying housing design, which contributes to overall system rigidity.
- High Load Capacity: The optimized raceway geometry and use of high-quality chrome steel enable it to handle significant radial loads.
- High-Speed Capability: The lightweight and durable stainless steel cage ensures stable operation and low friction, supporting the high limiting speed.
- Versatile Lubrication: The open seal type allows for the application of various greases or oils, enabling customization based on specific operational temperature ranges and speed requirements.
6410 NR Bearing Typical Application Areas
The 6410 NR bearing is ideally suited for applications requiring secure axial positioning and reliable radial load support. Common industries and equipment include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery where housing design simplification is desired.
