7006 CD/P4ATBTC Bearing Product Overview & Core Advantages
The 7006 CD/P4ATBTC is a precision angular contact ball bearing configured in a triplex back-to-back (TBT) matched set. Engineered for applications demanding exceptional rotational accuracy and rigidity, this bearing set is designed to accommodate combined loads (radial and axial) simultaneously. Its P4A tolerance class ensures superior running accuracy, making it ideal for high-speed, high-precision machinery requiring uncompromising performance and reliability.
7006 CD/P4ATBTC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing designation (30mm bore, 55mm OD, 13mm width per bearing). |
| C | 15° contact angle, optimized for high-speed applications with significant axial loads. |
| D | Indicates a moderate preload (Class C), enhancing system rigidity and minimizing deflection. |
| P4A | High precision tolerance class, specifying extremely tight dimensional and running accuracy. |
| TBT | Configuration as a Triplex Back-to-Back matched set of three bearings. |
| C (in cage context) | Phenolic (polyamide) cage material, contributing to low friction, high-speed capability, and reduced weight. |
7006 CD/P4ATBTC Bearing Structural Features & Performance Benefits
Exceptional Rigidity and Load Capacity: The triplex back-to-back arrangement creates a highly rigid bearing system capable of withstanding heavy combined loads and significant moment loads. This configuration provides stable and precise shaft positioning under demanding operating conditions.
High-Speed Performance: The combination of a 15° contact angle, a lightweight phenolic cage, and factory-applied lubrication enables a high limiting speed of 100,500 rpm, making it a true high-speed bearing solution.
Precision Engineering: Manufactured to P4A tolerance class with tight bore, outside diameter, and width tolerances, this bearing ensures minimal runout and vibration for superior performance in precision applications.
Optimized for Matched Sets: Supplied as a pre-matched triplex set, the bearings are manufactured to work in unison, ensuring even load distribution and consistent performance across the entire assembly.
