S71916 CE/HCP4A Bearing Product Overview & Core Advantages
The S71916 CE/HCP4A 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, making it an ideal solution for high-speed spindles and precision machinery. Its key advantages include the ability to handle combined radial and axial loads, superior high-speed capability facilitated by a phenolic cage and ceramic components, and a preloaded design for enhanced rigidity and rotational accuracy.
S71916 CE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| S7 | Series designation for high-precision angular contact ball bearings. |
| 1916 | Dimension series code indicating a bore diameter of 80 mm, an outside diameter of 110 mm, and a width of 16 mm. |
| CE | Signifies a 15° contact angle and a specific internal design optimized for high-speed operation and rigidity. |
| HC | Indicates the use of Hybrid Ceramic balls, which reduce friction, heat generation, and allow for higher limiting speeds. |
| P4A | Denotes a P4 tolerance class (ABEC-7) with enhanced running accuracy, ensuring minimal vibration and superior performance in precision applications. |
S71916 CE/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and extends bearing service life, especially under high-speed conditions.
Phenolic Resin Cage: This lightweight and robust cage material offers excellent dimensional stability and low friction, contributing directly to the bearing's high limiting speed of 19,000 rpm.
Super-Precision P4 Tolerance: Manufactured to P4 (ABEC-7) standards, this bearing guarantees extremely tight dimensional and running tolerances, resulting in superior rotational accuracy, reduced vibration, and enhanced machine tool finish quality.
15° Contact Angle & Preload: The 15° contact angle is optimized for applications requiring high rigidity and the ability to support significant axial loads in one direction. The preloaded arrangement ensures zero axial play, providing maximum system stiffness for precise positioning.
S71916 CE/HCP4A Bearing Typical Application Areas
The S71916 CE/HCP4A is ideally suited for high-performance machinery where precision, speed, and reliability are paramount. Key application areas include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
