312-2Z Bearing Product Overview & Core Advantages
The 312-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This shielded bearing excels at handling radial loads while also accommodating moderate axial loads in both directions. Its compact design, combined with high precision manufacturing to P0 tolerance class, makes it an ideal choice for applications requiring reliable operation and long service life. The pre-lubricated and shielded construction ensures immediate installation and consistent performance.
312-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 312 | Standard bearing series designation indicating metric dimensions (60mm bore, 130mm OD, 31mm width) | Ensures interchangeability and easy sourcing |
| 2Z | Non-contact steel shields on both sides | Provides effective contamination protection while maintaining high-speed capability |
312-2Z Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and high-grade chrome steel construction deliver a dynamic load rating of 20,525 lbf and a static load rating of 17,535 lbf, ensuring robust performance under significant radial stresses.
- High-Speed Operation: The lightweight nylon cage minimizes centrifugal forces, enabling a limiting speed of 4,800 rpm while maintaining stability and reducing friction.
- Sealed & Lubricated for Life: The 2Z shields retain the factory-applied grease lubrication and exclude contaminants, making the bearing suitable for maintenance-free operation in many applications.
- Precision Engineering: Manufactured to P0 tolerance class with CN radial internal clearance, providing consistent performance and smooth operation.
