S7016 CD/HCP4AQBCA Bearing Product Overview & Core Advantages
The S7016 CD/HCP4AQBCA is a high-precision quadruplex matched bearing set designed for the most demanding industrial applications. This P4A tolerance class angular contact ball bearing features a back-to-back (QBC) arrangement and ceramic balls, delivering exceptional rotational accuracy and high-speed capability. Its primary advantage lies in its ability to handle combined loads (radial and axial) simultaneously with superior rigidity and thermal stability, making it ideal for high-performance spindle systems.

S7016 CD/HCP4AQBCA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls provides superior high-speed performance, reduced friction, and extended service life compared to all-steel bearings. The lower density of ceramic balls reduces centrifugal forces, enabling higher limiting speeds (28,000 rpm).
Quadruplex Back-to-Back Arrangement: This matched set configuration of four bearings provides exceptional system rigidity and moment load capacity. The back-to-back arrangement offers better misalignment compensation and thermal stability than face-to-face configurations.
Precision Engineering: Manufactured to P4A tolerance class with phenolic cage for optimal performance at high speeds. The extra light preload (Class A) ensures minimal friction while maintaining precise rotational accuracy.
Sealed & Greased: The sealed design with factory-applied grease lubrication provides contamination protection and ensures immediate operational readiness within the specified temperature range of -30°C to 110°C.
