6403 Bearing Product Overview & Core Advantages
The 6403 single row deep groove ball bearing is a fundamental precision bearing designed for reliable performance in a wide range of industrial applications. Engineered to primarily support radial loads, this open-type bearing offers excellent versatility and cost-effectiveness. Manufactured to ABEC-1 tolerance standards, it ensures consistent operation and is an ideal choice for applications requiring dependable rotational accuracy and high-speed capability, with a limiting speed of 12,000 rpm.
6403 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6403 | Basic Model Number | Denotes a metric, single row deep groove ball bearing with a 17mm bore, 62mm OD, and 17mm width. |
| Open (No Seal/Shield suffix) | Seal Type | The bearing is supplied without seals or shields, allowing for higher speeds and facilitating custom lubrication schemes. It requires a clean operating environment or external sealing. |
| ABEC-1 | Tolerance Class | Specifies standard precision level for dimensional and running accuracy, suitable for most general industrial applications. |
| CN | Radial Internal Clearance | Indicates a "Normal" radial internal clearance group, which is standard for most operating conditions. |
6403 Bearing Structural Features & Performance Benefits
- Optimized Deep Groove Raceway: The uninterrupted deep groove geometry on both inner and outer rings enables smooth operation and efficient handling of radial loads and moderate axial loads in both directions.
- High-Speed Stainless Steel Cage: The stainless steel cage provides excellent strength and corrosion resistance, contributing to stable performance and a high limiting speed of 12,000 rpm.
- Robust Load Capacity: With a dynamic load rating of 5148 lbf and a static load rating of 2428 lbf, this bearing is built for durability and long service life under demanding conditions.
- Premium Material Construction: Both rings and balls are made from high-carbon chrome steel, ensuring high hardness, wear resistance, and dimensional stability across the operating temperature range of -30°C to 110°C.
- Flexible Lubrication: As an open bearing, it offers the flexibility to be lubricated with greases or oils specifically suited to the application's speed, temperature, and environmental requirements.
