7016 CE/P4AQBCB Bearing Product Overview & Core Advantages
The 7016 CE/P4AQBCB is a high-precision quadruplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This metric system bearing features a light preload (Class B) and is supplied as a matched set of four bearings in a back-to-back (QBC) arrangement. Its primary advantage lies in its ability to handle combined loads—significant radial and axial loads from both directions—simultaneously, making it ideal for high-stiffness, high-speed spindle systems where positional accuracy is critical.
7016 CE/P4AQBCB Bearing Model Code Explained, Specifications & Naming Convention
- 7016: Basic designation indicating a 80 mm bore and 125 mm outside diameter.
- CE: Internal design suffix indicating a 15° contact angle and optimized internal geometry.
- P4A: Tolerance class denoting very high dimensional and running accuracy, exceeding ABEC 7 standards.
- QBC: Denotes a Quadruplex Back-to-Back matched set, providing maximum rigidity and moment load capacity.
7016 CE/P4AQBCB Bearing Structural Features & Performance Benefits
Unmatched Rigidity and Load Capacity: The quadruplex back-to-back configuration creates an extremely rigid bearing system capable of withstanding heavy combined loads and moment loads, ensuring minimal deflection under operation.
High-Speed Capability: The phenolic resin cage is lightweight and robust, contributing to lower centrifugal forces and enabling a high limiting speed of 28,000 rpm. The standard lubrication is suitable for this operational range.
Precision Performance: Manufactured to a P4A tolerance class with tight bore, outside diameter, and width tolerances, this bearing ensures smooth, quiet running and high rotational accuracy.
Durability and Reliability: Constructed from chrome steel for both rings and balls, the bearing offers high fatigue life and durability within a temperature range of -30°C to 110°C.
7016 CE/P4AQBCB Bearing Typical Application Areas
This precision bearing is engineered for the most demanding machinery, including:
- High-Frequency Machine Tool Spindles (e.g., for milling, grinding, and drilling)
- Precision Grinding Spindles
- High-speed Industrial Pumps and Compressors
- Other applications requiring high rigidity and super-precision in a compact design.
