212-Z Bearing Product Overview & Core Advantages
The 212-Z metric ball bearing is a single row radial ball bearing featuring integral shields for robust protection. Engineered for high reliability in demanding applications, this bearing is designed to accommodate primarily radial loads while offering moderate axial load capacity. Its compact design, combined with a high-performance nylon cage and pre-lubrication, ensures smooth operation, low noise, and long service life, making it an excellent choice for a wide range of industrial machinery.
212-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 212 | Basic bearing series designation, defining the boundary dimensions (60mm bore, 110mm OD, 22mm width). | Standardized size for easy interchangeability and sourcing. |
| -Z | Denotes a bearing with a shielded (non-contact) seal on one side. | Effectively retains lubricant and excludes larger contaminants, enhancing bearing life with minimal impact on speed. |
212-Z Bearing Structural Features & Performance Benefits
- Shielded Design: The Z-shield provides a critical barrier against dust and debris while maintaining low friction, contributing to the bearing's high limiting speed of 6,700 rpm.
- High-Capacity Nylon Cage: The lightweight and durable nylon cage ensures precise ball guidance, reduces friction and heat generation, and is ideal for high-speed operation.
- Robust Load Ratings: Manufactured from chrome steel, this bearing offers a dynamic load rating of 12,612 lbf and a static load rating of 11,240 lbf, providing reliable performance under significant radial loads.
- Pre-Lubricated & Low Maintenance: Filled with grease and sealed, the bearing is ready for immediate use, offering a wide operating temperature range from -30°C to 120°C and reducing the need for re-lubrication.
- Standard Tolerance & Clearance: Built to P0 tolerance class and CN radial internal clearance, ensuring consistent performance and interchangeability for general industrial applications.
212-Z Bearing Typical Application Areas
The 212-Z is a versatile component suited for a multitude of applications requiring reliable radial load support and moderate speeds, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Conveyors
- Agricultural Machinery
- Pumps and Fans
