6308/C4W64 Bearing Product Overview & Core Advantages
The 6308/C4W64 is a single row deep groove ball bearing engineered for high-performance industrial applications. This metric bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. A key feature is its C4 radial internal clearance, making it particularly suitable for applications with significant thermal expansion or where interference fits are used. The integration of Soild Oil lubrication ensures long-term, maintenance-free operation across a wide temperature range, providing exceptional reliability and durability in demanding environments.
6308/C4W64 Bearing Model Code Explained, Specifications & Naming Convention
- 6308: Basic designation for a single row deep groove ball bearing with 40mm bore, 90mm OD, and 23mm width
- C4: Indicates greater radial internal clearance than normal (CN group)
- W64: Designates the bearing is pre-lubricated with Soild Oil (solid polymer lubricant)
6308/C4W64 Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The deep groove raceway and precision-ground components enable smooth operation and efficient load distribution, handling both radial and axial loads effectively.
Enhanced Thermal Performance: The C4 clearance accommodates differential thermal expansion between shaft and housing, preventing premature failure in applications with significant temperature variations.
Maintenance-Free Operation: The Soild Oil lubrication provides consistent lubrication throughout the bearing's service life, eliminating the need for re-lubrication and preventing contamination.
High-Speed Capability: With a limiting speed of 7,500 rpm and ABEC 1 precision, this bearing delivers reliable performance in high-speed applications while maintaining dimensional stability.
6308/C4W64 Bearing Typical Application Areas
The 6308/C4W64 is ideally suited for:
- Electric Motors and industrial gearboxes requiring maintenance-free operation
- Material Handling Equipment such as conveyor systems and pulleys
- Agricultural Machinery operating in harsh, contaminated environments
- Industrial Pumps and compressors where thermal expansion must be accommodated
- Ventilation Systems and fans requiring long-term reliability
