7016 ACD/P4ATBTA Bearing Product Overview & Core Advantages
The 7016 ACD/P4ATBTA is a precision angular contact ball bearing supplied as a matched triplex set in a back-to-back (TBT) arrangement. Engineered to the exacting P4A tolerance class, it is designed for applications demanding exceptional rotational accuracy, high rigidity, and reliable performance under combined loads. Its extra light preload (Class A) ensures smooth, precise operation with minimal runout, making it an ideal choice for high-precision spindles and machinery.
7016 ACD/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 ACD/P4ATBTA is decoded as follows:
- 7016: Basic series designation (70 Series, 80mm bore, 125mm OD).
- AC: Angular Contact design with a 25° contact angle.
- D: Signifies a matched set of bearings.
- P4A: Denotes a super-precision tolerance class, exceeding standard P4 levels for enhanced running accuracy.
- TBT: Specifies the Triplex Back-to-Back arrangement of the three bearings in the set.
- A: Indicates Extra Light Preload (Class A).
7016 ACD/P4ATBTA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The triplex back-to-back configuration creates an exceptionally rigid bearing system capable of supporting high combined radial and axial loads from both directions. The 25° contact angle is optimized for sustaining significant thrust loads.
- Precision & High-Speed Performance: Manufactured to P4A super-precision standards, this bearing ensures minimal vibration and superior running accuracy. The phenolic (polyamide) cage contributes to smooth operation at high speeds, with a limiting speed of 28,000 rpm.
- Optimized Internal Geometry: The design incorporates 20 high-grade chrome steel balls of 14.288 mm diameter, precisely arranged to maximize load distribution and service life.
- Pre-lubricated & Ready for Use: The bearing comes lubricated from the factory, simplifying installation and ensuring immediate, reliable operation within its specified temperature range.
7016 ACD/P4ATBTA Bearing Typical Application Areas
This high-precision, high-rigidity bearing set is primarily used in demanding applications such as:
- Machine Tool Spindles (e.g., for milling, grinding, and turning centers)
- High-Frequency Machining Centers
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Other high-performance machinery requiring superior stiffness and rotational accuracy.
