6306 Y/C78 Bearing Product Overview & Core Advantages
The 6306 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. Engineered to primarily handle radial loads, this open-type bearing is characterized by its high-speed capability and robust construction. Manufactured from high-grade chrome steel for all its core components, it offers reliable operation and long service life. Its ABEC 1 (ISO P0) tolerance class and standard CN radial internal clearance make it a versatile and cost-effective solution for general machinery requiring dependable rotational accuracy.
6306 Y/C78 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 63 | Series code indicating a medium width and medium diameter deep groove ball bearing. |
| 06 | Bore diameter code, representing a 30 mm bore (06 * 5 = 30 mm). |
| No Suffix | Indicates a standard, open bearing with no seals or shields, and no special internal design. |
6306 Y/C78 Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The deep groove raceway and single row design are engineered to efficiently support high radial dynamic load ratings (6002 lbf), making it suitable for applications with significant radial forces.
- High-Speed Capability: With a limiting speed of 9,600 rpm, this bearing is capable of operating in demanding high-rotation environments. The pressed steel cage ensures stable operation at these velocities.
- Robust Construction: The use of chrome steel for the rings, balls, and cage provides high hardness, wear resistance, and dimensional stability under load.
- Versatile Operating Range: A wide temperature range from -30°C to 120°C allows for use in various environmental conditions.
- Precision & Consistency: Manufactured to ABEC 1 (ISO P0) tolerance standards, it ensures consistent running accuracy for general precision applications.
