6304/HN3C3LD8VG201 Bearing Product Overview & Core Advantages
The 6304/HN3C3LD8VG201 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This precision bearing features a C3 radial internal clearance and an open design, making it ideal for applications requiring high-speed operation and accommodating thermal expansion. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable and consistent performance, providing robust support for radial loads with its optimized internal geometry and high-grade chrome steel construction.
6304/HN3C3LD8VG201 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 63 | Series designation indicating medium duty and specific dimension series. |
| 04 | Bore diameter code, corresponding to a 20 mm bore. |
| HN3 | Indicates a specific cage design and material (Chrome Steel). |
| C3 | Specifies a greater than normal radial internal clearance, suitable for applications with thermal expansion or where interference fits are used. |
| LD8VG201 | Internal manufacturer's code, potentially relating to specific manufacturing process, heat treatment, or performance grade. |
6304/HN3C3LD8VG201 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The optimized single row deep groove design and chrome steel cage contribute to a high limiting speed of 14,000 rpm, making it an excellent choice for high-speed applications.
- Robust Load Capacity: With a dynamic load rating of 3574 lbf and a static load rating of 1765 lbf, this bearing is engineered to handle significant radial loads reliably.
- Thermal Stability: The specified C3 radial clearance allows for differential thermal expansion between the shaft and housing, preventing premature failure due to thermal binding.
- Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures smooth operation and reduced vibration, contributing to the overall precision of the machinery.
- Material Integrity: Constructed entirely from chrome steel for rings, balls, and cage, providing high hardness, wear resistance, and durability.
