Engineered to primarily accommodate radial loads, this bearing features an open design for versatile lubrication options. Manufactured from high-grade chrome steel with a stainless steel cage, it offers reliable operation and long service life. Its P0 tolerance class and standard CN radial internal clearance ensure consistent performance, making it a robust and cost-effective solution for a wide range of industrial machinery.
313 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 313 | Basic model number denoting a metric single row deep groove ball bearing with a 65mm bore, 140mm OD, and 33mm width. |
| No Seal Suffix | The bearing is open (unsealed), allowing for custom lubrication schemes but requiring a clean operating environment or external sealing. |
| P0 | Indicates standard tolerance class (Normal class). |
| CN | Specifies standard radial internal clearance for normal operating conditions. |
313 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and optimized geometry enable high radial dynamic load rating (22,931 lbf) and radial static load rating (20,233 lbf), providing robust support for heavy-duty applications.
- Versatile Speed Performance: With a limiting speed of 5,300 rpm, it is suitable for a broad range of operational speeds. The lightweight stainless steel cage contributes to stable high-speed operation.
- Durable Construction: Rings and balls made from chrome steel provide high hardness and wear resistance. The stainless steel cage offers excellent corrosion resistance and strength.
- Precision & Reliability: Manufactured to P0 tolerance class, it ensures dimensional consistency and smooth running, which is critical for reducing vibration and noise.
- Broad Operating Range: A temperature range of -30°C to 120°C allows for use in various environmental conditions.
