7014 CD/P4ADBA Bearing Product Overview & Core Advantages
The 7014 CD/P4ADBA is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This metric bearing features a back-to-back (DB) matched arrangement, enabling it to withstand combined radial and axial loads from both directions. Manufactured to a P4A tolerance class with an extra light preload, it delivers superior running precision and is ideally suited for high-speed, high-rigidity spindles and other precision machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7014 | Basic bearing series and size designation (70mm Bore, 110mm OD, 40mm Width). |
| C | 15° contact angle. |
| D | Duplex (Two bearings in a matched set). |
| DB | Back-to-Back mounting arrangement. |
| P4A | High precision tolerance class, exceeding ABEC 7/ISO P4 standards. |
7014 CD/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DB) configuration creates a rigid support system that effectively resists moment loads and can handle significant combined loads.
- Precision Performance: Manufactured to P4A tolerance with extremely tight dimensional runouts, ensuring smooth, quiet operation and high positional accuracy.
- Optimized High-Speed Operation: The lightweight phenolic resin cage and 15° contact angle are engineered to minimize centrifugal forces and friction, supporting a high limiting speed of 22,000 rpm.
- Superior Material Construction: Rings and balls made from high-grade chrome steel provide excellent durability and fatigue life under demanding operating conditions.
7014 CD/P4ADBA Bearing Typical Application Areas
