706 CD/P4A Bearing Product Overview & Core Advantages
The 706 CD/P4A is a single-row angular contact ball bearing designed for applications demanding high precision and superior running accuracy. Engineered to a P4 (ABEC-7) tolerance class, it is optimized to accommodate combined loads, primarily thrust loads in one direction, with a 15° contact angle for excellent high-speed performance. Its phenolic resin cage and pre-lubrication contribute to its reliable operation at limiting speeds up to 180,000 rpm, making it an ideal choice for compact, high-performance spindle assemblies.
706 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 706 | Basic bearing series designation. |
| CD | Indicates a 15° contact angle and specific internal design optimized for high precision and high-speed operation. |
| P4 | Specifies the tolerance class equivalent to ABEC-7, ensuring extremely tight dimensional and running accuracy. |
| A | Denotes that the bearing is supplied with a specific preload for enhanced rigidity and precise rotational performance. |
706 CD/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4 tolerance standards and supplied with a preload, this bearing delivers exceptional rotational accuracy and high rigidity, minimizing deflection under load.
