6305/VM117 Bearing Product Overview & Core Advantages
The 6305 is a single row deep groove ball bearing designed for exceptional performance in radial load applications. Characterized by its open design and metric dimensions, this bearing offers a robust solution for a wide range of industrial machinery. Its construction from high-grade chrome steel ensures durability and reliable operation. A key advantage is its high limiting speed of 11,000 rpm, making it suitable for demanding, high-rotation environments. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent and precise performance for general engineering applications.
6305/VM117 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 63 | Series Code | Indicates a medium-duty, single row deep groove ball bearing series. |
| 05 | Bore Diameter Code | Specifies a 25 mm bore diameter (05 x 5 = 25mm). |
| (No Suffix) | Open / No Seal | The bearing is supplied open (unsealed), allowing for custom lubrication solutions and optimal heat dissipation in clean environments. |
6305/VM117 Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The single row deep groove raceway geometry is precision-engineered to efficiently support high radial dynamic load ratings of 4631 lbf.
- High-Speed Capability: The combination of an open design, a chrome steel cage, and a CN radial internal clearance enables a high limiting speed of 11,000 rpm, reducing friction and heat generation.
- Precision and Consistency: Manufactured to ABEC 1 (ISO P0) tolerance class with strict dimensional controls on the bore diameter, outside diameter, and width, ensuring smooth and reliable operation.
- Robust Material Construction: All core components—rings, balls, and cage—are made from chrome steel, providing high hardness, wear resistance, and a long operational lifespan.
- Application Flexibility: The open seal type and no pre-lubrication allow engineers to select the most suitable lubricant for specific operating conditions, including a wide temperature range from -30°C to 120°C.
