71907 CDTP/HCP4B Bearing Product Overview & Core Advantages
The 71907 CDTP/HCP4B is a single-row angular contact ball bearing engineered for applications demanding high precision and high-speed performance. Positioned in the P4 (ABEC-7) tolerance class, it is designed to handle significant combined loads, primarily thrust loads in one direction, while offering excellent running accuracy. Its compact design, featuring a 35 mm bore and a 10 mm width, makes it ideal for space-constrained, high-performance assemblies. The use of ceramic balls and a phenolic cage contributes to reduced weight, lower friction, and superior performance at high rotational speeds.
71907 CDTP/HCP4B Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| 71907 | Basic bearing series and size designation (35mm bore, 55mm OD, 10mm width). |
| C | Specifies a 15° contact angle, optimized for high-speed applications and high thrust capacity. |
| DTP | Indicates a duplex pair configuration. This bearing is one of a preloaded matched set (Tandem arrangement) designed for maximum rigidity and axial stability. |
| HC | Denotes Hybrid Ceramic construction, featuring steel rings and ceramic (Si3N4) balls. |
| P4B | Specifies a P4 tolerance class with additional running accuracy requirements, exceeding standard ABEC-7 for superior precision. |
71907 CDTP/HCP4B Bearing Structural Features & Performance Benefits
- High-Speed & High-Rigidity Performance: The combination of a 15° contact angle, a lightweight phenolic resin cage, and hybrid ceramic construction enables a very high limiting speed of 32,000 rpm. The preloaded duplex (DTP) arrangement provides exceptional system rigidity, minimizing deflection under load.
- Superior Load Capacity: As an angular contact ball bearing, it is designed to support combined (radial and axial) loads, with a high thrust capacity in one direction. The dynamic load rating of 2194 lbf ensures long service life under demanding conditions.
- Enhanced Operational Efficiency: Ceramic balls are lighter, harder, and smoother than steel, leading to significantly lower centrifugal forces, reduced friction, and less heat generation. This results in lower operating temperatures and higher efficiency.
- Precision & Accuracy: Manufactured to P4B tolerance class, this bearing guarantees minimal runout and vibration, which is critical for applications requiring extreme positional accuracy and smooth operation.
71907 CDTP/HCP4B Bearing Typical Application Areas
The 71907 CDTP/HCP4B is ideally suited for high-performance machinery where speed, precision, and rigidity are paramount. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and drilling spindles.
- Precision Instrumentation: High-speed measuring and testing equipment.
- Robotics: Arm joints and high-accuracy gearboxes.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and auxiliary power units (APUs).
- High-Frequency Motors and Spindles: Used in PCB drilling, dental handpieces, and other specialist applications.
