6308-Z/W64 Bearing Product Overview & Core Advantages
The 6308-Z/W64 is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Its core advantage lies in its ability to efficiently handle radial loads and moderate axial loads in both directions. This bearing is characterized by its shielded design and factory-filled Solid Oil lubrication, offering a maintenance-free, long-service-life solution. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable operation and is an excellent choice for applications demanding high reliability and cost-effectiveness.
Model Code Breakdown
- 6308: Basic model number denoting a medium-duty, single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width.
- -Z: Suffix indicating that one side of the bearing is fitted with a shield (non-contact, metal shield). This protects the bearing interior from large contaminants while minimizing friction.
- /W64: Suffix indicating the bearing is lubricated with Solid Oil. This is a polymer matrix saturated with oil, providing consistent lubrication, resistance to wash-out, and a wide operating temperature range.
6308-Z/W64 Bearing Structural Features & Performance Benefits
The performance of the 6308-Z/W64 is derived from its specific construction:
- High Load Capacity & Versatility: The deep groove raceway and chrome steel construction enable high radial dynamic load rating (915 lbf) and radial static load rating (5395 lbf), making it suitable for combined loads.
- Maintenance-Free Operation: The combination of the Z-shield and Solid Oil (W64) lubrication creates a sealed, pre-lubricated unit. This eliminates the need for re-lubrication, reduces maintenance costs, and prevents lubricant contamination.
- Reliable High-Speed Performance: With a limiting speed of 7,500 rpm, the bearing is capable of high-speed operation. The stable Solid Oil lubrication and precision ABEC 1 manufacturing contribute to smooth running and reduced vibration.
- Durability: Manufactured entirely from chrome steel (rings, balls, and cage), the bearing offers high strength and resistance to wear, ensuring a long operational lifespan.
6308-Z/W64 Bearing Typical Application Areas
The 6308-Z/W64 is ideally suited for a variety of applications where reliability and minimal maintenance are key:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
- Pumps and Fans
- General Industrial Machinery
