S71910 CDTP/HCP4B Bearing Product Overview & Core Advantages
The S71910 CDTP/HCP4B is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This single-row bearing is distinguished by its ceramic balls and P4 (ABEC-7) super-precision tolerance, enabling superior high-speed operation and minimal vibration. Its 15° contact angle is optimized for handling combined radial and axial loads simultaneously. Pre-loaded and factory-lubricated, it offers outstanding rigidity and operational reliability in a compact design, making it an ideal solution for high-spindle applications.
S71910 CDTP/HCP4B Bearing Model Code Explained, Specifications & Naming Convention
The model number S71910 CDTP/HCP4B provides detailed technical specifications through its suffixes:
- S: Denotes a bearing with a high-precision specification.
- 71910: Indicates the bearing series and size (10mm bore x 72mm OD x 12mm width).
- CD: Signifies a 15° contact angle.
- T: Indicates a phenolic (synthetic resin) cage.
- P: Denotes a preloaded bearing set for enhanced rigidity.
- HC: Stands for Hybrid Ceramic, featuring ceramic balls and steel rings.
- P4B: Specifies the P4 (ABEC-7) tolerance class with specific running accuracy requirements.
S71910 CDTP/HCP4B Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic (Si3N4) balls significantly reduces centrifugal forces, lowers operating temperature, and extends service life, especially at high speeds.
- Phenolic Resin Cage: This lightweight and robust cage material offers excellent dimensional stability and low friction, contributing to the bearing's high limiting speed of 22,000 rpm.
- Super-Precision P4 Tolerance: Manufactured to the tightest dimensional and running accuracy standards, this ensures smooth, quiet operation with minimal runout, which is critical for high-precision spindles.
- Preload & Rigidity: The bearing is supplied as a preloaded set, which maximizes system stiffness, improves rotational accuracy, and dampens vibrations.
- Optimized Lubrication: Factory-applied lubrication ensures immediate readiness and reliable performance within the specified temperature range of -30°C to 110°C.
S71910 CDTP/HCP4B Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery where speed, precision, and reliability are paramount. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Motors
- Dental and Medical Handpieces
