6207-ZNBR/C3 Bearing Product Overview & Core Advantages
The 6207-ZNBR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is distinguished by its shielded design and a snap ring groove on the outer ring, facilitating secure axial location within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable operation and consistent quality. A key feature is its C3 radial internal clearance, which accommodates thermal expansion in applications with elevated operating temperatures or where fits result in a reduction of internal clearance. This makes it an excellent choice for applications requiring high reliability and stable operation under radial loads.
6207-ZNBR/C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6207-ZNBR/C3 provides detailed technical specifications through its suffixes:
- 6207: Standard designation for a single row deep groove ball bearing with a 35mm bore and 72mm outside diameter.
- Z: Signifies that the bearing is shielded on one side. This provides protection against contaminant ingress while minimizing friction.
- N: Indicates a snap ring groove on the outer ring. This feature allows for simplified axial positioning and secure mounting.
- BR: Specifies the material of the cage, which in this case is Chrome Steel, offering high strength and durability.
- C3: Denotes a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, heavy interference fits, or where misalignment may be a factor.
6207-ZNBR/C3 Bearing Structural Features & Performance Benefits
The design of the 6207-ZNBR/C3 translates into distinct performance advantages:
- Robust Construction & High Load Capacity: Built entirely from Chrome Steel (rings, balls, and cage), this bearing delivers a dynamic load rating of 5778 lbf and a static load rating of 3462 lbf, ensuring longevity under significant radial loads.
- Secure Axial Location: The integrated snap ring groove on the outer ring eliminates the need for complex housing shoulders, simplifying assembly and providing a reliable method for axial positioning.
- Contaminant Protection: The shielded (Z) design effectively protects the bearing's internals from dust and debris, enhancing service life in less-than-ideal environments.
- Operational Flexibility: The C3 clearance ensures stable performance in applications prone to thermal expansion, preventing binding and reducing friction and heat generation.
- High-Speed Capability: With a limiting speed of 9,200 rpm, it is suitable for a wide range of high-speed machinery.
6207-ZNBR/C3 Bearing Typical Application Areas
The 6207-ZNBR/C3 is versatile and finds use in numerous sectors requiring reliable rotational support:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment such as conveyor systems
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
