707 CD/P4A Bearing Product Overview & Core Advantages
The 707 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 pre-loaded and pre-lubricated, making it ideal for high-speed spindles and other precision machinery where exceptional rotational accuracy and rigidity are paramount. Its compact design efficiently accommodates combined loads, primarily handling thrust loads in one direction alongside radial loads.
707 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| CD | A specific internal design and preload specification for high-precision applications. | Ensures consistent, low-vibration operation and high system rigidity. |
| P4A | Indicates a P4 (ABEC-7) tolerance class with specific accuracy requirements for the bearing's width and inner ring runout. | Guarantees ultra-high dimensional and running accuracy for demanding applications. |
707 CD/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4 tolerance class and supplied with a preload, this bearing delivers minimal runout and high axial rigidity, which is critical for the stability of precision spindles.
- Optimized for High-Speed Operation: The lightweight phenolic resin cage minimizes centrifugal forces and reduces friction, contributing to the high limiting speed of 160,000 rpm. The 15° contact angle provides an excellent balance between radial and thrust load capacity at high speeds.
- Superior Load Capacity: The precision-ground chrome steel rings and balls enable high dynamic and static load ratings, reliably handling combined loads.
- Ready-to-Install: The bearing is pre-lubricated, simplifying installation and ensuring immediate, reliable performance upon startup.
707 CD/P4A Bearing Typical Application Areas
This high-precision bearing is ideally suited for:
- High-Frequency Spindles for PCB drilling and precision machining
- Precision Grinding Spindles
- High-Speed Motors and encoders
- Medical and Dental Handpieces
- Instrumentation and other equipment requiring exceptional rotational accuracy
