6309 TC/C782 Bearing Product Overview & Core Advantages
The 6309 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. Engineered to primarily support radial loads, its fundamental design ensures smooth operation and high reliability. This bearing features a standard open design and is manufactured to ABEC 1 (ISO P0) precision class, making it a cost-effective and versatile solution for general machinery. Its robust construction from chrome steel provides excellent durability and a long service life.
6309 TC/C782 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6309 follows a standard industry designation. A breakdown of its key characteristics is provided below:
| Code Segment | Technical Meaning |
|---|---|
| 63 | Series designation indicating medium duty and specific dimensional series. |
| 09 | Bore diameter code. For metric bearings, this signifies a 45 mm bore (09 x 5 = 45 mm). |
| (No Suffix) | Indicates a standard, open bearing with no seals or shields, and no pre-lubrication (Lubrication: None). The standard radial internal clearance is CN. |
6309 TC/C782 Bearing Structural Features & Performance Benefits
The 6309 bearing's performance is derived from its fundamental design and material selection:
- High Load Capacity: The single row deep groove raceway geometry is optimized to handle significant radial loads (dynamic: 11915 lbf, static: 7194 lbf), and can accommodate moderate axial loads in both directions.
- Versatile Speed Performance: With a limiting speed of 6,700 rpm, it is suitable for a broad spectrum of high-speed applications.
- Robust Construction: All core components—rings, balls, and cage—are made from high-grade chrome steel, ensuring high strength, wear resistance, and dimensional stability.
- Standard Precision & Clearance: Manufactured to ABEC 1 (ISO P0) tolerance and standard CN radial internal clearance, it provides reliable and consistent performance for most industrial uses.
- Flexible Lubrication: The open design allows for the use of various lubricants (oil or grease) tailored to specific operating conditions, including a wide temperature range from -30°C to 120°C.
