Product Overview & Key Advantages
The 310-ZNBR is a single row deep groove ball bearing designed for radial load applications requiring reliable performance. This metric bearing features a shielded design on one side for contaminant protection while maintaining high operational capability. Its construction with chrome steel rings and balls ensures durability and consistent performance under standard industrial conditions. The inclusion of a snap ring groove on the outer ring facilitates secure and simplified mounting in housings, making it an efficient solution for applications where precise axial location is beneficial.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 310 | Standard bearing series designation, indicating specific internal dimensions and load capacity. |
| Z | Signifies a shielded (non-contact) configuration on one side to protect against large particulate contaminants. |
| N | Indicates a snap ring groove machined on the outer ring for axial retention. |
| BR | Designates bearing construction with chrome steel components and standard CN radial internal clearance. |
310-ZNBR Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers excellent resistance to wear and fatigue, ensuring a long service life under radial dynamic loads up to 14,478 lbf.
Simplified Mounting & Retention: The snap ring groove on the outer ring allows for secure axial positioning within a housing, eliminating the need for complex housing shoulders or press fits in many applications. This feature enhances assembly efficiency and reliability.
Contaminant Protection: The single shielded side helps prevent the ingress of large contaminants, protecting the internal bearing components and maintaining performance in less-than-clean environments. The open side allows for initial lubrication if required.
Standardized Performance: Built to ABEC 1 | ISO P0 tolerance class and standard CN radial internal clearance, this bearing provides consistent and predictable operation suitable for a wide range of general industrial uses.
