6302 TN9/C3 Bearing Product Overview & Core Advantages
The 6302 TN9/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This metric bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable operation and precise rotation. A key feature is its C3 radial internal clearance, which makes it suitable for applications involving thermal expansion or where interference fits are used. The Nylon cage (TN9) contributes to quiet operation, lower friction, and is ideal for high-speed applications, with a limiting speed of 17,000 rpm.
6302 TN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 6302 | Basic Bearing Series & Size | Indicates a standard 15mm bore, 42mm OD, 13mm width single row deep groove ball bearing. |
| TN9 | Cage Type | Polyamide (Nylon) cage, glass fiber reinforced. Offers low weight, excellent acceleration characteristics, and is suitable for high speeds and temperatures up to 120°C. |
| C3 | Radial Internal Clearance | Greater than normal clearance. Compensates for tight fits or thermal expansion in the housing/shaft, preventing premature failure due to excessive preload. |
6302 TN9/C3 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Geometry: The raceway design allows for smooth operation under combined (radial and axial) loads, providing versatile performance.
High-Speed Nylon Cage (TN9): This cage material reduces centrifugal forces, lowers friction, and dampens vibrations, enabling the bearing to achieve its high limiting speed of 17,000 rpm with minimal noise.
C3 Internal Clearance: This radial internal clearance is a critical feature for applications where thermal conditions or press-fits can reduce operational clearance. It ensures optimal performance and longevity by preventing seizure.
Premium Chrome Steel: Both the rings and balls are made from high-grade chrome steel, providing high load capacity, durability, and resistance to wear. The open seal type allows for easy relubrication if required, though it is supplied without grease for application-specific lubrication.
6302 TN9/C3 Bearing Typical Application Areas
The 6302 TN9/C3 is a versatile component found in a wide range of industrial machinery due to its high-speed capability and robust load rating. Key application areas include:
- Electric Motors and Small Gearboxes
- Pumps and Compressors
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
- Industrial Fans and Blowers
