S7016 ACD/HCP4AQBCC Bearing Product Overview & Core Advantages
The S7016 ACD/HCP4AQBCC is a high-precision quadruplex back-to-back angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This matched bearing set features a moderate preload (Class C) and is manufactured to P4A tolerance class, ensuring superior running accuracy and dimensional stability. Its primary advantage lies in its ability to handle combined radial and axial loads simultaneously with high rigidity, making it ideal for high-speed, high-precision machinery where uncompromising performance is critical.
S7016 ACD/HCP4AQBCC Bearing Model Code Explained, Specifications & Naming Convention
- S7016: Basic bearing series and size (Bore: 80mm, OD: 125mm, Width: 88mm)
- A: 25° contact angle, optimized for axial load capacity
- CD: Polyamide (Phenolic) cage design
- HC: Hybrid Ceramic - featuring ceramic balls and steel rings
- P4A: Ultra-precision tolerance class
- QBCC: Quadruplex Back-to-Back arrangement with Moderate (Class C) preload
S7016 ACD/HCP4AQBCC Bearing Structural Features & Performance Benefits
Enhanced Rigidity & Load Capacity: The quadruplex back-to-back configuration provides exceptional system rigidity, enabling the bearing set to withstand heavy combined loads and moments. The 25° contact angle is optimized for substantial axial load carrying capacity in both directions.
High-Speed Performance: The combination of ceramic balls (lower density, reduced centrifugal forces) and phenolic cage allows for superior high-speed operation, achieving a limiting speed of 28,000 rpm. This hybrid ceramic construction also provides improved stiffness and reduced thermal expansion.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring precise shaft positioning and minimal runout for applications demanding the highest accuracy.
Preloaded & Matched Set: The four bearings are universally matched and preloaded at the factory (Moderate/Class C), eliminating the need for complex adjustment during installation and ensuring consistent, predictable performance.
