|---|---|
| 7016 | Standard bore diameter (80 mm) and series designation. |
| AC | Angular Contact design with a 25° contact angle. |
| BGA | Indicates the use of Ceramic (Silicon Nitride) balls. |
| HC | Refers to the Phenolic Resin (Hybrid Composite) cage. |
| P4A | Denotes a super-precision tolerance class, tighter than ABEC 7. |
7016 ACBGA/HCP4A Bearing Structural Features & Performance Benefits
- Super-Precision Performance: Manufactured to P4A tolerance class with extremely tight dimensional runouts, ensuring minimal vibration and superior running accuracy for critical applications.
- High-Speed Capability: The combination of a lightweight phenolic cage and low-density ceramic balls reduces centrifugal forces, enabling a high limiting speed of 28,000 rpm.
- Rigidity and Load Capacity: The 25° contact angle is optimized to handle high thrust loads in combination with radial loads, providing excellent operational rigidity.
- Universal Matching Design (SU): This bearing is universally matchable, allowing two bearings to be mounted in a back-to-back (DB) or face-to-face (DF) arrangement without selective assembly, simplifying installation and optimizing preload.
- Extended Service Life: Ceramic balls offer superior wear resistance, lower thermal expansion, and electrical insulation properties compared to steel, significantly enhancing bearing longevity in harsh conditions.
7016 ACBGA/HCP4A Bearing Typical Application Areas
