71806 CD/P4DGBVT162 Bearing Product Overview & Core Advantages
The 71806 CD/P4DGBVT162 is a precision angular contact ball bearing designed for high-performance applications. Engineered as a universally matchable single-row bearing, it is typically supplied in a light preload (Class B) and paired set of two. Its primary advantage lies in its ability to handle combined loads—significant radial loads and axial loads in one direction—simultaneously. The optimized 15° contact angle and phenolic cage contribute to exceptional high-speed capabilities and smooth operation, making it ideal for machine tool spindles and other high-precision, high-reliability systems.
71806 CD/P4DGBVT162 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71806 | Basic bearing series, indicating a metric, single-row angular contact design. |
| CD | Indicates a universal matchable design. Two bearings can be mounted together in various configurations (e.g., back-to-back, face-to-face) to optimize load handling. |
| P4 | Specifies a high tolerance class (equivalent to ABEC 7/P4), ensuring extremely tight dimensional and running accuracy for precision applications. |
| DGB | Denotes a light preload (Class B). This preload eliminates internal clearance, enhancing system rigidity and rotational accuracy. |
| VT162 | Signifies the bearing is lubricated with grease (code VT162), suitable for the specified operating temperature range. |
71806 CD/P4DGBVT162 Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The single-row design with a 15° contact angle and light preload provides high axial and radial stiffness, minimizing deflection under load for superior positional accuracy.
Superior Load Capacity: Engineered to support combined loads effectively. The dynamic and static load ratings ensure reliable performance under demanding conditions.
Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground chrome steel components and optimized internal geometry enable a high limiting speed of 83,000 rpm.
Universal Matchability: The CD designation allows for flexible mounting of two bearings. This simplifies assembly and enables the creation of a stiffer, pre-loaded bearing system capable of handling complex load scenarios.
71806 CD/P4DGBVT162 Bearing Typical Application Areas
This high-precision, high-speed angular contact bearing is ideally suited for:
- Machine Tool Spindles: High-speed machining centers, grinding spindles.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- High-Frequency Motors and Spindles: Where high rotational speed and rigidity are critical.
- Medical and Dental Equipment: High-speed handpieces and scanners.
- Aerospace Actuation Systems: Precision control mechanisms.
