Double Row Angular Contact Ball Bearing 3307-a High Precision for CNC Machine Tools

Product Specifications

Application Suitability

Need a High Precision Double Row Angular Contact Ball Bearing 3307 for CNC Machine Tools?

CNC machine operators know the frustration of bearing-related downtime—whether it's premature wear from low-quality materials or precision issues causing machining errors. Sourcing the right angular contact bearing that balances radial and axial load capacity while maintaining tight tolerances can be time-consuming, especially when dealing with multiple suppliers for different brands.

Engineered for CNC Machine Tool Reliability

This Double Row Angular Contact Ball Bearing 3307 addresses these challenges with its separated design and high precision ratings (P0 to P6), making it suitable for the demanding rotational speeds and load requirements of CNC machine tool spindles. As a supplier with access to a comprehensive range of SKF bearings and related products, we ensure you get the exact specifications needed without the hassle of multiple vendor relationships. Our large-scale inventory supports quick availability for critical replacement needs, minimizing production interruptions.

Optimal Performance in CNC Spindle Applications

Designed to handle both radial and axial loads, this angular contact ball bearing excels in CNC machine tool environments where precision and rigidity are paramount. Its double row structure provides higher load capacity compared to single row designs, making it ideal for high-speed spindle applications operating under varying load conditions. The choice of steel, copper, or nylon cages allows customization based on specific speed and temperature requirements, ensuring compatibility with different CNC machining processes.

Key Engineering Features for CNC Performance

The bearing's precision rating options directly impact machining accuracy—P4 and P5 classes offer tighter dimensional tolerances for high-precision cutting operations, while P0 provides a cost-effective solution for general CNC applications. The separated design simplifies installation and maintenance, allowing for easier bearing replacement without dismantling the entire spindle assembly. Constructed from high-quality bearing steel, it delivers excellent wear resistance and fatigue strength, crucial for extended machine tool uptime. The dual lubrication options (oil or grease) cater to different operating speeds, with grease lubrication suitable for standard applications and oil lubrication preferred for high-speed scenarios.

Why Precision Bearings Reduce Total Cost of Ownership

Choosing the right double row angular contact ball bearing directly affects your CNC machine's total cost of ownership. A bearing with inadequate precision can lead to poor surface finishes, increased tool wear, and frequent rework—costs that far exceed the initial price difference between standard and high-precision options. This SKF 3307 Double Row Bearing's design minimizes vibration and heat generation, extending both bearing life and the service intervals of surrounding components. By reducing unplanned downtime and maintenance requirements, it contributes to more consistent production schedules and lower long-term operational costs.
