S7007 CDTP/P4B Bearing Product Overview & Core Advantages
The S7007 CDTP/P4B is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, this bearing excels in high-speed scenarios while simultaneously handling combined radial and axial loads. Its compact design, featuring a 14mm width, makes it an ideal solution for space-constrained, high-performance machinery where reliability and precision are paramount.
S7007 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| S7007 | Bearing Series & Size Designation | Indicates a 35mm bore, 62mm OD, 14mm width bearing from a high-precision series. |
| C | 15° Contact Angle | Optimized for high-speed operation and moderate axial load capacity. |
| DT | Duplex Tandem Arrangement | Two bearings are mounted in tandem to increase axial load capacity in one direction. |
| P | Preload | The bearing is supplied with a preload to increase system rigidity and minimize deflection under load. |
| P4 | Tolerance Class (ABEC-7) | Denotes ultra-precision manufacturing tolerances for superior running accuracy and low vibration. |
| B | Modified Internal Clearance/Contact Angle | Indicates a specific internal design optimized for the preload and performance requirements. |
S7007 CDTP/P4B Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The duplex tandem (DT) arrangement combines two bearings to significantly enhance axial load-carrying capacity in one direction, providing superior system stiffness that is critical for applications like machine tool spindles.
Superior High-Speed Performance: The phenolic resin cage is lightweight and possesses excellent sliding properties, contributing to lower friction and enabling the high limiting speed of 24,000 rpm. The standard 15° contact angle is ideal for these high rotational speeds.
Precision Engineering: Manufactured to P4 tolerance class, this bearing ensures minimal runout and vibration, which is essential for achieving high surface finishes and positional accuracy in precision equipment.
Optimized for Performance: The bearing comes with a preload (P) applied, which eliminates internal clearance and increases the bearing's natural frequency, resulting in improved dynamic response and stability under operating conditions.
S7007 CDTP/P4B Bearing Typical Application Areas
The S7007 CDTP/P4B is engineered for high-performance applications where speed, precision, and rigidity are non-negotiable. Key industries and machinery include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- Aerospace & Defense: Gyroscopes, radar systems, and auxiliary power units.
- High-Frequency Motors and Spindles: PCB drilling spindles and dental handpieces.
