6305-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6305-2RS1/C3WT is a metric single row deep groove ball bearing engineered for high reliability in demanding applications. Its sealed design provides robust protection against contamination, while the optimized internal geometry ensures smooth operation and long service life. A key feature is its C3 radial internal clearance, making it particularly suitable for applications with elevated operating temperatures or where interference fits are used, ensuring stable performance under these conditions. This bearing is designed to handle primarily radial loads and is an excellent choice for general industrial machinery requiring a durable and cost-effective solution.
Model Code Breakdown
- 6305: Basic model number denoting a metric single row deep groove ball bearing with a 25mm bore, 62mm outside diameter, and 17mm width.
- 2RS1: Signifies that the bearing is equipped with two contact seals (one on each side) made from NBR rubber. These seals provide effective protection against the ingress of contaminants and the egress of lubricant.
- C3: Indicates a greater than normal radial internal clearance. This is selected for applications involving thermal expansion, shaft or housing misalignment, or heavy interference fits to prevent operational issues.
- WT: This suffix is not a standard designation for this specific bearing configuration. Based on the provided specifications indicating "Lubrication: None", the bearing is supplied without grease. Please consult manufacturer data for precise suffix interpretation.
6305-2RS1/C3WT Bearing Structural Features & Performance Benefits
The performance of the 6305-2RS1/C3 is derived from its robust construction and design features. The deep groove raceway and single row of balls enable it to support significant radial loads. The inclusion of two rubber contact seals (2RS1) ensures a high degree of protection against dust, dirt, and moisture, significantly extending the bearing's service life in harsh environments. The C3 clearance is a critical performance feature, accommodating thermal expansion and preventing pre-loading that can lead to premature failure, thereby enhancing operational reliability. Manufactured to ABEC 1 | ISO P0 tolerance class, it offers dependable performance for a wide range of industrial applications.
6305-2RS1/C3WT Bearing Typical Application Areas
This versatile bearing is commonly specified in various industrial sectors due to its sealed and robust design. Typical applications include:
- Electric Motors and Gearboxes
- Material Handling Equipment such as conveyor rollers
- Agricultural Machinery
- Industrial Fans and Blowers
- General machinery requiring sealed bearing units for protection
