213-Z Bearing Product Overview & Core Advantages
The 213-Z is a single row deep groove ball bearing designed for robust performance in demanding applications. Engineered to primarily accommodate radial loads, this bearing features a shielded design (Z-type) for contaminant protection and is pre-lubricated with grease for long-term, maintenance-free operation. Its construction from high-grade chrome steel and a lightweight nylon cage ensures reliable operation, making it an excellent choice for applications requiring a balance of durability, speed capability, and cost-effectiveness.
213-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 213 | Standard bearing series designation, defining the bearing dimensions (65mm bore, 120mm OD, 23mm width). | Ensures dimensional interchangeability and simplifies sourcing. |
| -Z | Denotes a shielded bearing on one side. | Protects against contamination while allowing for higher limiting speeds compared to contact seals. |
Note: The absence of additional suffixes indicates standard P0 tolerance class and CN radial internal clearance.
213-Z Bearing Structural Features & Performance Benefits
Optimized for Radial Load Capacity: The single row deep groove raceway geometry is precision-engineered to efficiently support high radial dynamic and static loads (13,601 lbf and 13,151 lbf respectively), providing stable and reliable performance.
Shielded & Pre-Lubricated Design: The non-contact steel shield retains the factory-applied grease lubrication, protecting the internal components from dust and debris. This design contributes to a long service life and maintenance-free operation within the specified temperature range.
High-Speed Capability with Nylon Cage: The lightweight nylon cage minimizes friction and inertial forces, enabling a high limiting speed of 6,000 rpm. This makes the bearing suitable for a wide range of high-speed applications.
Precision and Material Integrity: Manufactured to P0 tolerance class with chrome steel rings and balls, the bearing ensures consistent performance, low noise, and vibration, which is critical for smooth operation.
213-Z Bearing Typical Application Areas
The 213-Z bearing is versatile and finds use in numerous industrial sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Ventilation and Fan Systems
- Various Automotive Components
