6705 Bearing Product Overview & Core Advantages
The 6705 metric ball bearing is a precision-engineered single row deep groove ball bearing designed for reliable performance in compact spaces. Characterized by its open design and ABEC-1 precision class, this bearing delivers excellent radial load capacity and smooth operation. Its minimal cross-section (4mm width) and lightweight construction (7.1g) make it ideal for applications where space and weight are critical constraints while maintaining robust performance.
6705 Bearing Model Code Explained, Specifications & Naming Convention
| Code Element | Technical Meaning |
|---|---|
| 6705 | Standard metric series, 25mm bore diameter, 32mm OD |
| Open | No seals or shields, allowing for custom lubrication schemes |
| ABEC-1 | Standard precision tolerance class for reliable performance |
| C0 | Normal radial internal clearance (0.006-0.020mm) |
6705 Bearing Structural Features & Performance Benefits
Optimized Load Handling: The single row deep groove construction enables efficient radial load distribution with a dynamic load rating of 248 lbf and static rating of 189 lbf. The raceway geometry is engineered to handle moderate axial loads in both directions.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with bore diameter tolerance of -0.01mm to 0 and outside diameter tolerance of -0.011mm to 0, ensuring consistent performance and reliable fit in precision assemblies.
High-Speed Capability: The stainless steel cage and optimized internal geometry support limiting speeds up to 8,000 rpm, making it suitable for various high-speed applications.
Material Excellence: Constructed from chrome steel rings and balls with stainless steel cage, providing excellent durability and corrosion resistance in the operating temperature range of -30°C to 110°C.
