6313-2ZNR Bearing Product Overview & Core Advantages
The 6313-2ZNR is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This shielded bearing features a snap ring groove on its outer ring, enabling secure axial location within a housing. Engineered from high-grade chrome steel, it offers a robust solution for primarily radial loads. Its key advantages include simplified installation due to the snap ring, effective contamination protection from the integral shields, and reliable operation with pre-applied grease lubrication, making it a versatile and durable choice for a wide range of machinery.

| 2Z | Bearing is shielded on both sides. | Protects against contaminants while allowing for high-speed operation compared to contact seals. |
| NR | Outer ring has a snap ring groove and a snap ring is fitted. | Provides secure axial location, simplifying housing design and assembly. |
6313-2ZNR Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing is built for durability. It boasts a high radial dynamic load rating of 21,919 lbf and a radial static load rating of 13,489 lbf, ensuring reliable performance under significant stress.
- Secure Axial Location: The integrated snap ring (fitted) eliminates the need for complex housing shoulders or end caps, providing a cost-effective and reliable method for axial positioning.
- Contamination Protection & Long Service Life: The non-contact shields (2Z) effectively keep out dust and debris while retaining the factory-applied grease lubrication. This combination supports a long, maintenance-free service life within the specified temperature range of -30°C to 120°C.
- Precision & Speed: As a standard P0 tolerance class bearing with CN radial internal clearance, it offers consistent performance. The optimized design and shielding contribute to a limiting speed of 5,300 rpm.
6313-2ZNR Bearing Typical Application Areas
The 6313-2ZNR is ideally suited for applications requiring reliable radial load support and simplified mounting. Common uses include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Any machinery where secure axial location of the bearing outer ring is critical.
