S7016 CE/HCP4A Bearing Product Overview & Core Advantages
The S7016 CE/HCP4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. This single-row bearing features a 15° contact angle, enabling it to support combined radial and axial loads simultaneously. Manufactured to P4 (ABEC-7) tolerance class, it guarantees superior running accuracy. Its construction with ceramic balls and a phenolic cage contributes to lower friction, higher limiting speed, and extended service life, making it an ideal choice for high-performance machinery.
S7016 CE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | Indicates the use of Ceramic (Hybrid) balls. | Reduces friction and heat generation, allows for higher speeds, and provides electrical insulation. |
| HC | Refers to the Phenolic (Polyamide) Cage material. | Offers excellent strength-to-weight ratio, reduced centrifugal forces, and quiet operation at high speeds. |
| P4A | Specifies the P4 (ABEC-7) tolerance class and 15° contact angle. | Ensures ultra-precise rotational accuracy and optimized load capacity for high-speed applications. |
S7016 CE/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Design: The combination of chrome steel rings and ceramic balls significantly reduces friction and operating temperature, enabling a high limiting speed of 17,500 rpm. This design also mitigates the risk of electrical arcing damage.
- High-Speed Phenolic Cage: The lightweight and robust phenolic cage ensures stable ball guidance and minimal centrifugal force, which is critical for maintaining bearing integrity and smooth operation at extreme rotational velocities.
- Precision & Rigidity: Manufactured to P4 tolerance with a 15° contact angle, this bearing provides high running accuracy and rigidity, effectively handling combined loads with minimal deflection.
- Pre-lubricated & Sealed: The bearing comes lubricated and sealed, protecting against contamination and providing long-term, maintenance-free operation within its specified temperature range.
