7016 CE/P4AQBCA Bearing Product Overview & Core Advantages
The 7016 CE/P4AQBCA is a precision angular contact ball bearing designed for applications demanding exceptional rigidity and accuracy. As part of a Quadruplex Back-to-Back (QBC) matched set, this bearing is engineered to handle significant combined loads (radial and axial) simultaneously. Its P4A tolerance class ensures ultra-precise running accuracy, making it ideal for high-speed spindles and other critical machinery where high rigidity and operational reliability are paramount.
7016 CE/P4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 CE/P4AQBCA provides detailed technical specifications:
- 7016: Basic bearing series and size designation (80mm bore, 125mm OD, 88mm width).
- C: Represents a 15° contact angle, optimized for high-speed applications and axial load capacity.
- E: Indicates an optimized internal design, often for higher speeds and reduced noise.
- P4A: Denotes a super-precision tolerance class with specific running accuracy requirements.
- QBC: Signifies the bearing is part of a Quadruplex Back-to-Back matched set of 4 bearings, providing maximum system rigidity.
- A: Indicates an Extra light preload for minimal friction and optimal high-speed performance.
7016 CE/P4AQBCA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The Quadruplex Back-to-Back (QBC) arrangement creates an exceptionally stiff bearing system, capable of supporting high combined radial and axial loads from multiple directions. This configuration is crucial for minimizing shaft deflection under heavy loads.
- Precision & High-Speed Performance: Manufactured to P4A super-precision standards and featuring a phenolic resin cage, this bearing achieves smooth operation and a high limiting speed of 28,000 rpm. The 15° contact angle further enhances its suitability for high-speed applications.
- Superior Material & Construction: Made from chrome steel for both rings and balls, the bearing ensures high durability and long service life under demanding conditions. The open seal type allows for customized lubrication schemes to match specific operational needs.
7016 CE/P4AQBCA Bearing Typical Application Areas
This high-precision bearing is specifically engineered for advanced industrial machinery, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Gearboxes and High-Frequency Motors.
- Aerospace & Defense Systems: Gyroscopes, radar equipment, and other precision mechanisms.
- Medical Equipment: High-speed dental handpieces and imaging device rotors.
