312-ZN Bearing Product Overview & Core Advantages
The 312-ZN is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels in handling significant radial loads and moderate axial loads in one direction. Its key advantages include a shielded design for contaminant protection, a snap ring groove on the outer ring for simplified axial location, and a standard CN radial internal clearance suitable for a wide range of operating conditions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable, cost-effective performance for general industrial use.
Model Code Breakdown
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| ZN | Snap Ring Groove on Outer Ring | Simplifies axial positioning and bearing housing design, reducing assembly complexity and cost. |
| - | Shielded on One Side | Protects against contaminants while allowing for higher limiting speeds compared to sealed variants. |
312-ZN Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway geometry and chrome steel construction enable a high radial dynamic load rating of 20,525 lbf and a radial static load rating of 17,535 lbf, ensuring durability under heavy loads.
- Simplified Mounting: The integral snap ring groove eliminates the need for complex housing shoulders or end caps, facilitating easier installation and secure axial location.
- Contaminant Protection: The shielded design helps retain lubrication and exclude larger particulate contaminants, contributing to extended bearing service life in typical industrial environments.
- Standard Precision & Clearance: Built to ABEC 1 | ISO P0 tolerance with CN group radial internal clearance, this bearing provides consistent, reliable performance for a vast majority of applications without the cost of higher precision grades.
