S7014 ACB/P4ADBC Bearing Product Overview & Core Advantages
The S7014 ACB/P4ADBC is a precision duplex angular contact ball bearing specifically designed for demanding applications requiring exceptional rigidity and rotational accuracy. This metric sealed bearing features a back-to-back (DB) matched arrangement with a moderate preload (Class C), enabling it to handle combined radial and axial loads simultaneously. Manufactured to P4A tolerance class, it delivers superior running accuracy and is ideal for high-speed, high-rigidity applications where operational reliability is critical.
S7014 ACB/P4ADBC Bearing Model Code Explained, Specifications & Naming Convention
- S7014: Basic bearing series and size designation (70mm bore, 110mm OD, 40mm width).
- AC: Angular Contact design with a 25° contact angle.
- B: Indicates a 40° contact angle (Note: Specification shows 25°, please verify the exact angle with technical datasheet).
- /P4A: Denotes high precision tolerance class P4A, ensuring extremely tight dimensional and running accuracy.
- DB: Specifies the Duplex Back-to-Back mounting arrangement, providing high moment rigidity.
- C: Indicates moderate preload (Class C) applied to the bearing set.
S7014 ACB/P4ADBC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a rigid bearing system capable of withstanding combined loads and moment loads effectively. With a dynamic load rating of 6660 lbf and static load rating of 6975 lbf, it offers reliable performance under significant stress.
Precision Engineering: Manufactured to P4A tolerance class with tight bore, outside diameter, and width tolerances, this bearing ensures minimal runout and vibration for high-precision applications.
Optimized High-Speed Performance: The phenolic resin cage and 28 high-grade chrome steel balls contribute to stable operation at high speeds, with a limiting speed of 28,000 rpm.
Sealed & Lubricated for Life: As a sealed bearing pre-lubricated with grease, it operates effectively within a temperature range of -30°C to 110°C, offering long service life with minimal maintenance requirements.
