6213-RS1/C3 Bearing Product Overview & Core Advantages
The 6213-RS1/C3 is a single row deep groove ball bearing designed for reliable performance in demanding industrial applications. This sealed bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a generous C3 radial internal clearance for applications involving thermal expansion or shaft misalignment, and integrated contact seals (RS1) that effectively retain lubricant and exclude contaminants, ensuring long service life with minimal maintenance.
6213-RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6213 | Standard designation for a single row deep groove ball bearing with a 65mm bore, 120mm OD, and 23mm width. | Defines the core bearing dimensions and type. |
| RS1 | Indicates the bearing is fitted with a synthetic rubber contact seal on one side. | Provides excellent protection against contamination and retains lubricant, enhancing bearing life. |
| /C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Ideal for applications with expected thermal expansion, shaft misalignment, or where a heavier interference fit is used. |
6213-RS1/C3 Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Manufactured from high-grade chrome steel for rings, balls, and cage, this bearing ensures consistent performance and durability under its substantial radial dynamic load rating of 12,859 lbf.
Optimized for Contaminated Environments: The RS1 contact seal is a critical feature, creating an effective barrier against dust, moisture, and other particulates. This makes the bearing suitable for applications where cleanliness is difficult to maintain.
Accommodates Operational Stresses: The C3 clearance is a key performance feature, preventing excessive preload and potential seizure that can occur due to thermal expansion of the shaft and housing during operation.
Standard Precision for General Applications: With an ABEC 1 | ISO P0 tolerance class, this bearing offers reliable and cost-effective performance for a wide range of industrial machinery without the need for ultra-high precision.
6213-RS1/C3 Bearing Typical Application Areas
The 6213-RS1/C3 is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators: Used as a reliable support bearing where sealed protection is required.
- Industrial Gearboxes and Transmissions: Handles radial loads and accommodates operational heat.
- Material Handling Equipment: Conveyor pulleys and rollers benefit from its sealed and robust design.
- Agricultural Machinery: Performs well in harsh, dusty environments common in farming equipment.
- Ventilation and Fan Systems: A common choice for fan shaft support due to its balance of speed capability and sealed protection.
