6330 Bearing Product Overview & Core Advantages
The 6330 single row deep groove ball bearing is a precision bearing engineered for high-performance applications requiring exceptional radial load capacity and operational stability. Featuring an open design and manufactured to P6 tolerance class, it delivers superior running accuracy and rotational precision. Its robust construction from chrome steel ensures high durability and reliability, making it an ideal choice for demanding industrial environments where consistent performance under substantial radial dynamic loads is critical.
6330 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Interpretation |
|---|---|
| 63 | Series designation indicating a medium width, deep groove ball bearing. |
| 30 | Bore diameter code, corresponding to a 150 mm bore diameter. |
| No Seal Suffix | Open (non-contact) seal type, allowing for high-speed operation and easy relubrication. |
| (Implied) | P6 Tolerance Class, signifying higher dimensional and running accuracy than standard bearings. |
| (Implied) | CN Radial Internal Clearance, representing the standard (normal) clearance group. |
6330 Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The single row deep groove raceway and optimized geometry are designed to support significant radial dynamic loads (62,047 lbf) and static loads (64,071 lbf), ensuring long service life under heavy-duty conditions.
- Precision & High-Speed Performance: Manufactured to a P6 tolerance class, this bearing offers excellent running accuracy and low vibration. The open design, combined with precision components, contributes to a high limiting speed of 2,800 rpm.
- Robust Material Construction: Both rings and balls are made from high-carbon chrome steel, providing high hardness, wear resistance, and the ability to withstand a wide temperature range from -30°C to 120°C.
- Flexible Lubrication: The open seal type allows for the use of various lubricants tailored to specific application needs, including high-speed grease or oil systems, offering superior flexibility for maintenance and performance optimization.
