213 Bearing Product Overview & Core Advantages
The 213 is a metric single row deep groove ball bearing designed for radial load applications requiring reliable performance. Engineered with precision-ground chrome steel components and a lightweight nylon cage, this bearing offers an optimal balance of high load capacity and moderate speed capability. Its open design facilitates easy relubrication, while standard P0 tolerance and CN clearance ensure consistent performance in general industrial applications, making it a versatile and cost-effective solution.
213 Bearing Model Code Explained, Specifications & Naming Convention
| Code Element | Technical Meaning |
|---|---|
| 213 | Standard bearing series designation indicating bearing dimensions (65mm bore, 120mm OD, 23mm width) |
| Open | No seals or shields, allowing for maximum speed performance and easy maintenance access |
| P0 | Normal tolerance class (ISO Class 0) for general precision applications |
| CN | Normal radial internal clearance standard for most operating conditions |
213 Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway geometry enables efficient handling of radial dynamic load rating up to 13,601 lbf while accommodating moderate axial loads in both directions.
Enhanced Operational Efficiency: The nylon cage material reduces friction and weight, contributing to smoother operation at limiting speeds up to 6,000 rpm while providing excellent corrosion resistance.
Precision Engineering: Manufactured with tight bore diameter tolerance (-0.015mm to 0) and consistent dimensional stability, ensuring reliable performance and easy installation in various applications.
Material Excellence: Constructed from high-quality chrome steel for both rings and balls, delivering superior durability and wear resistance across the operating temperature range of -30°C to 120°C.
