6309 Y/C782 Bearing Product Overview & Core Advantages
The 6309 is a single row deep groove ball bearing designed for exceptional performance in general industrial applications. Engineered to primarily handle radial loads, it features a simple yet robust open design that facilitates high-speed operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable precision and is characterized by its high limiting speed and substantial dynamic and static load ratings, making it a versatile and cost-effective solution for a wide range of machinery.
6309 Y/C782 Bearing Model Code Explained, Specifications & Naming Convention
- 63: Indicates the bearing series, defining the cross-sectional dimensions and load capacity profile.
- 09: Specifies the bore diameter. For this metric bearing, the bore diameter is calculated as 09 * 5 = 45 mm.
Key Omitted Suffixes & Implications: The absence of any suffix codes indicates this is a standard, open (unsealed) bearing with CN normal radial internal clearance and no pre-lubrication. This makes it suitable for applications where external sealing and lubrication systems are provided.
6309 Y/C782 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and optimized geometry, combined with a chrome steel cage, minimize friction and heat generation, enabling a high limiting speed of 6,700 rpm.
- Robust Load Capacity: The deep groove raceways and high-quality chrome steel construction provide excellent radial dynamic (11,915 lbf) and static (7,194 lbf) load ratings, ensuring long service life under demanding conditions.
- Standard Precision: Manufactured to ABEC 1 (ISO P0) tolerance class, this bearing guarantees consistent running accuracy and smooth operation for most industrial applications.
- Material Integrity: All core components—rings, balls, and cage—are made from high-grade chrome steel, offering excellent hardness, wear resistance, and dimensional stability.
