6212-ZNBR/C3VK504 Bearing Product Overview & Core Advantages
The 6212-ZNBR/C3VK504 is a single row deep groove ball bearing engineered for robust performance in demanding industrial environments. This metric bearing features a shielded design and a snap ring groove on the outer ring, facilitating secure and simplified mounting. Its ABEC 1 (ISO P0) tolerance and C3 radial internal clearance ensure reliable operation under varying thermal and load conditions, making it an excellent choice for applications requiring consistent performance and high reliability.
6212-ZNBR/C3VK504 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| Z | Steel Shield on One Side | Protects against contaminants while allowing for high-speed operation. |
| N | Snap Ring Groove on Outer Ring | Enables axial location and secure mounting without a housing shoulder. |
| BR | Brass Cage | Provides high strength and stability, suitable for high-speed applications. |
| C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads. |
| VK504 | Contact Seal on One Side | Offers superior sealing for harsh environments, though may slightly reduce the limiting speed. |
6212-ZNBR/C3VK504 Bearing Structural Features & Performance Benefits
This bearing's construction delivers distinct performance advantages. The single row deep groove geometry is optimized for handling significant radial loads, while also capable of supporting moderate axial loads in both directions. The combination of a brass cage (BR) and high-grade chrome steel components ensures dimensional stability and durability, contributing to a high limiting speed of 5,600 rpm. The snap ring groove (N) enhances design flexibility by providing a positive locking mechanism. The specified C3 clearance is critical for applications prone to thermal expansion, preventing preload and ensuring smooth operation. The dual sealing approach with a shield (Z) and a contact seal (VK504) offers robust protection against contamination, extending service life in challenging conditions.
6212-ZNBR/C3VK504 Bearing Typical Application Areas
The 6212-ZNBR/C3VK504 is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Industrial Fans and Blowers
Its combination of a snap ring groove, robust sealing, and C3 clearance makes it a preferred choice for applications where secure mounting, environmental resistance, and accommodation for thermal effects are paramount.
