S7014 ACD/P4A Bearing Product Overview & Core Advantages
The S7014 ACD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 25° contact angle, it is optimized to handle combined loads—significant radial loads alongside high unidirectional axial loads. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it ideal for high-speed spindles and other high-precision machinery. The bearing comes preloaded and pre-lubricated from the factory, simplifying installation and providing immediate, reliable performance.
S7014 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S7014 ACD/P4A provides detailed technical specifications through its suffixes:
- S7014: Denotes the basic bearing series and size (70mm bore, 110mm OD).
- A: Indicates a 25° contact angle, optimized for high axial load capacity.
- CD: Specifies a polyamide (Phenolic) cage, which is lightweight and suitable for high-speed operation.
- P4A: Defines the tolerance class P4 (ABEC-7) and a specific internal clearance/geometry for preload.
S7014 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4 tolerance with a preload, the bearing minimizes axial and radial play, providing exceptional system stiffness and positioning accuracy for precision applications.
- Superior Load Capacity: The 25° contact angle and robust construction using chrome steel rings and balls enable high radial dynamic load rating (10980 lbf) and excellent axial load carrying capability.
- Optimized High-Speed Performance: The lightweight phenolic cage (CD) reduces centrifugal forces, allowing for a high limiting speed (11,000 rpm). This makes it a true high-speed bearing.
- Sealed and Lubricated for Long Life: As a sealed and lubricated unit, it is protected from contamination and is ready for use, offering a long service life within its specified temperature range (-30° to 110°C).
S7014 ACD/P4A Bearing Typical Application Areas
