7012 CD/P4ADT Bearing Product Overview & Core Advantages
The 7012 CD/P4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. This duplex tandem (DT) arrangement consists of two matched bearings preloaded against each other, delivering superior axial rigidity and the ability to handle significant combined loads. Manufactured to the exacting P4A tolerance class, it is ideally suited for high-speed spindles and other precision machinery where uncompromising performance is critical.
7012 CD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| C | 15° Contact Angle | Optimized for high-speed operation with excellent axial load capacity. |
| D | Duplex Tandem (DT) Arrangement | Two bearings are mounted in tandem to maximize axial load capacity and rigidity in one direction. |
| P4A | High Precision Tolerance Class | Provides extremely tight running accuracy for applications requiring minimal runout and vibration. |
7012 CD/P4ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex tandem arrangement and 15° contact angle create an exceptionally rigid setup capable of withstanding heavy combined radial and axial loads in one direction.
- High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, contributing to a high limiting speed of 34,000 rpm. The standard lubrication ensures stable operation at these velocities.
- Precision Engineering: Conforming to P4A tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, this bearing guarantees precise shaft positioning and smooth, quiet operation.
- Durable Construction: Made from chrome steel for both rings and balls, the bearing offers high fatigue resistance and long service life under demanding conditions.
7012 CD/P4ADT Bearing Typical Application Areas
This bearing is engineered for high-performance applications, including:
- Machine Tool Spindles (e.g., for milling, grinding)
- High-Frequency Motors
- Precision Gearboxes
- Industrial Pumps and Compressors
