7014 ACE/P4ADBG10GMM2 Bearing Product Overview & Core Advantages
The 7014 ACE/P4ADBG10GMM2 is a precision angular contact ball bearing configured as a duplex back-to-back (DB) matched set. Engineered for applications demanding exceptional rotational accuracy and rigidity, this bearing excels at handling combined radial and axial loads simultaneously. Its P4A tolerance class ensures ultra-precise running, making it ideal for high-speed spindles and other critical machinery where maximum performance and reliability are required.
7014 ACE/P4ADBG10GMM2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7014 | Basic bearing series and size designation (70mm bore, 110mm OD, 40mm width). |
| ACE | 25° contact angle, standard internal clearance, and phenolic resin cage. |
| P4A | Indicates a high-precision tolerance class with enhanced running accuracy requirements. |
| DB | Signifies a duplex back-to-back arrangement of two bearings, providing high moment stiffness. |
| G10 | Specifies the axial preload level applied to the matched set for optimal rigidity. |
| GMM2 | Identifies the specific grease lubrication used, suitable for the specified temperature range. |
7014 ACE/P4ADBG10GMM2 Bearing Structural Features & Performance Benefits
- High Rigidity & Moment Load Capacity: The duplex back-to-back (DB) arrangement creates a wide effective spread, significantly increasing the bearing set's resistance to moment loads and providing exceptional system stiffness.
- Optimized Load Handling: The 25° contact angle is engineered to efficiently support substantial combined radial and axial loads, making it suitable for complex loading conditions.
- High-Speed Performance: The lightweight phenolic resin cage ensures stable operation and low friction at high rotational speeds, contributing to the bearing's limiting speed of 29,000 rpm.
- Precision & Accuracy: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, guaranteeing precise shaft positioning and smooth, quiet running.
- Preloaded & Ready-to-Mount: The set is supplied with a G10 preload, eliminating the need for complex adjustment during installation and ensuring immediate, optimal performance.
7014 ACE/P4ADBG10GMM2 Bearing Typical Application Areas
