7016 CDGC/P4A Bearing Product Overview & Core Advantages
The 7016 CDGC/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single bearing with a 15° contact angle and Moderate (Class C) preload, it is engineered to support high-speed operations while accommodating significant combined loads. Its P4A tolerance class ensures superior running accuracy, making it ideal for high-reliability and high-precision machinery where minimal runout and vibration are critical.
7016 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 CDGC/P4A is decoded as follows:
- 7016: Basic series designation, indicating a metric angular contact ball bearing with an 80mm bore and 125mm outside diameter.
- C: Signifies a 15° contact angle, optimized for high-speed performance and moderate axial load capacity.
- DG: Indicates a Universal Matchable (SU) bearing. This specific bearing is one of a set of 3 that can be universally matched in any combination to achieve a specific preload or rigidity without selective mounting.
- C: Denotes a Moderate preload (Class C), providing enhanced rigidity for the application.
- P4A: Specifies the tolerance class, which is stricter than ABEC 7, guaranteeing extremely tight dimensional and running accuracy tolerances.
7016 CDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The P4A super-precision tolerances and moderate preload work in concert to deliver a very stiff and stable rotational axis, crucial for applications like machine tool spindles.
- Optimized Load Capacity: The 15° contact angle effectively handles combined (radial and axial) loads, with a dynamic load rating of 14,625 lbf and a static load rating of 13,725 lbf.
- Superior High-Speed Performance: The lightweight phenolic resin cage and optimized internal geometry contribute to a high limiting speed of 17,000 rpm, reducing centrifugal forces and operational temperatures.
- Universal Matching Capability: The Universal Matchable (SU) designation allows for flexible arrangement of bearings from a matched set, simplifying installation and ensuring consistent, predictable performance in duplex or triplex configurations.
7016 CDGC/P4A Bearing Typical Application Areas
This bearing is specified for high-performance applications where speed, precision, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Internal and external grinding machines.
- High-Frequency Motors and Spindles
- Industrial Pumps and Compressors
- Aerospace and Defense Positioning Systems
