6213 NR Bearing Product Overview & Core Advantages
The 6213 NR is a single row deep groove ball bearing designed for exceptional performance in radial load applications. Its key distinguishing feature is the snap ring groove and fitted snap ring on its outer ring, which provides a secure and cost-effective method for axial location within a housing, simplifying assembly and reducing the need for complex housing shoulders. Manufactured from high-grade chrome steel with a stainless steel cage, this bearing offers reliable operation, high limiting speeds, and is supplied in the standard P0 tolerance class with CN radial internal clearance, making it a versatile and robust solution for a wide range of industrial machinery.
6213 NR Bearing Model Code Explained, Specifications & Naming Convention
- 6213: Basic model number denoting a medium-duty, single row deep groove ball bearing with a 65mm bore, 120mm OD, and 23mm width.
- NR: This suffix indicates that the bearing is fitted with a snap ring (N) located in a groove on the outer ring (R). This feature allows for simplified axial positioning.
Key Inherent Features (Not shown in code):
- Open: No seals or shields, allowing for high-speed operation and custom lubrication schemes.
- P0: Standard dimensional and geometrical tolerance class.
- CN: Standard, normal range of radial internal clearance.
6213 NR Bearing Structural Features & Performance Benefits
Snap Ring for Axial Location: The integrated snap ring is a critical structural feature. It enables the bearing to be positively located in the axial direction within a housing, eliminating the need for complex and expensive housing shoulders or end caps. This design simplifies the overall assembly process and reduces manufacturing costs.
High-Speed Capability: The open design, combined with a lightweight and durable stainless steel cage, allows the 6213 NR to achieve high limiting speeds (7,500 rpm). The absence of seals minimizes friction and heat generation.
Robust Load Capacity: The optimized raceway geometry and use of high-quality chrome steel for rings and balls provide a high dynamic load rating and static load rating, ensuring long service life under significant radial loads.
Material & Construction: The bearing components are manufactured from chrome steel (GCr15), offering high hardness and wear resistance. The stainless steel cage provides excellent corrosion resistance and durability.
6213 NR Bearing Typical Application Areas
The 6213 NR is ideally suited for applications requiring reliable radial load support with simplified axial location. Common industries and equipment include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Any machinery where a secure, snap-ring based mounting solution is preferred for housing design.
