S7014 ACDTP/P4B Bearing Product Overview & Core Advantages
The S7014 ACDTP/P4B is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. As a single-row bearing, it is optimized to handle combined loads—significant radial loads and axial loads in one direction simultaneously. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it ideal for high-speed spindles and other precision machinery. The bearing comes preloaded and pre-lubricated, facilitating simplified installation and immediate, reliable operation.
S7014 ACDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S7014 | Standard designation for a 70mm bore, 110mm OD angular contact ball bearing. |
| AC | Angular Contact design with a 25° contact angle. |
| DTP | Indicates a specific internal design and preload level for high rigidity. |
| P4B | Denotes a P4 (ABEC-7) tolerance class for high-precision applications. |
S7014 ACDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 25° contact angle and factory-applied preload provides exceptional system stiffness, minimizing deflection under load for superior positional accuracy.
- Superior Load Capacity: Engineered to support high radial dynamic load ratings (10,980 lbf) and substantial one-direction axial loads simultaneously, making it suitable for demanding combined load conditions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed (11,000 rpm). The precision-ground chrome steel rings and balls ensure smooth, low-vibration operation.
- Ready-to-Install & Sealed: As a sealed and lubricated unit, it is protected from contamination and is supplied with grease suitable for its specified temperature range (-30° to 110°C), ensuring long service life with minimal maintenance.
