6306 ETN9/C3 Bearing Product Overview & Core Advantages
The 6306 ETN9/C3 is a single row deep groove ball bearing engineered for superior performance in demanding applications. This metric bearing is characterized by its open design and C3 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or where interference fits are used. Its high limiting speed and robust dynamic and static load ratings ensure reliable operation under significant radial loads. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent precision and durability for industrial machinery.
6306 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 63: Deep Groove Ball Bearing Series
- 06: Bore Diameter Code (30 mm)
- E: Optimized internal design for enhanced load capacity and performance
- TN9: Nylon (Polyamide) cage, offering reduced weight, lower friction, and excellent performance at high speeds
- C3: Greater radial internal clearance than normal (CN), suitable for applications with thermal gradients or heavy interference fits
6306 ETN9/C3 Bearing Structural Features & Performance Benefits
The single row design with a deep groove raceway provides exceptional radial load capacity. The use of a Nylon (TN9) cage is a key performance differentiator, contributing to lower rotational mass, quieter operation, and superior performance at the high limiting speed of 9,600 rpm. The C3 internal clearance ensures reliable performance in operational conditions that generate heat, preventing pre-load and potential seizure. Constructed entirely from chrome steel, the bearing offers high strength and resistance to wear, ensuring a long service life even under continuous operation within its specified temperature range.
6306 ETN9/C3 Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of industrial applications, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
