7014 ACD/HCP4ATT Bearing Product Overview & Core Advantages
The 7014 ACD/HCP4ATT is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance. This metric system bearing features a triplex tandem (3-DT) matched arrangement, providing superior axial rigidity and the ability to handle significant combined loads. Manufactured to P4A tolerance class, it delivers high running accuracy. The combination of a ceramic ball material and a phenolic cage contributes to its high-speed capability, low friction, and extended service life, making it an ideal choice for high-precision, high-reliability machinery.
7014 ACD/HCP4ATT Bearing Model Code Explained, Specifications & Naming Convention
- 7014: Basic designation indicating a 70mm bore, 110mm OD bearing.
- ACD: Signifies an Angular Contact design with a 25° contact angle.
- HC: Denotes a Hybrid Ceramic construction (steel rings with ceramic balls).
- P4A: Identifies the tolerance class, specifying very high precision levels for bore, outside diameter, and width.
- T: Indicates a Tandem arrangement within the matched set.
- T (second occurrence): Specifies the Phenolic (Textolite) cage material.
7014 ACD/HCP4ATT Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The triplex tandem arrangement of three preloaded bearings creates an exceptionally rigid system, capable of withstanding heavy combined radial and axial loads in one direction. This configuration is engineered for maximum stability in precise applications.
High-Speed Performance: The lightweight phenolic cage and low-density ceramic balls reduce centrifugal forces, enabling a high limiting speed. This makes the bearing suitable for high-speed spindle applications.
Pre-Lubricated & Preloaded: The bearing comes lubricatedpreloaded matched set, ensuring immediate optimal performance, simplified installation, and reduced maintenance requirements.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, this bearing guarantees high running accuracy and consistent performance.
