7006 CE/HCP4ADT Bearing Product Overview & Core Advantages
The 7006 CE/HCP4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance. This duplex tandem (DT) arrangement features two preloaded bearings, delivering superior high rigidity and axial load capacity in one direction. Manufactured to a P4A tolerance class, it ensures ultra-high running accuracy. The use of ceramic balls and a phenolic cage enables outstanding high-speed performance, with a limiting speed of 100,500 rpm, making it ideal for machine tool spindles and other high-precision, high-velocity machinery.
7006 CE/HCP4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 26mm width). |
| C | Designates a 15° contact angle, optimized for high-speed operation and combined loads. |
| E | Indicates an optimized internal design for enhanced performance. |
| HC | Signifies the use of Hybrid Ceramic balls (Silicon Nitride), which reduce friction and heat generation. |
| P4A | Denotes an ultra-precision tolerance class with very tight dimensional and running accuracy limits. |
| DT | Specifies a Duplex Tandem matched set of two bearings, designed to handle very high unidirectional axial loads. |
7006 CE/HCP4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex tandem arrangement with preload creates an exceptionally rigid bearing system. This configuration is engineered to withstand significant combined loads, particularly very high unidirectional axial loads, providing stable and precise shaft positioning.
Superior High-Speed Performance: The combination of lightweight ceramic balls and a phenolic resin cage minimizes centrifugal forces and ensures stable operation at extreme rotational speeds up to 100,500 rpm. This results in lower operating temperatures and extended service life.
Precision Engineering: Manufactured to P4A tolerance class with tight bore, outside diameter, and width tolerances, this bearing guarantees minimal runout and vibration, which is critical for applications demanding the highest levels of accuracy.
Optimized for Lubrication: The bearing comes lubricated from the factory, ready for immediate installation and operation within its specified temperature range.
7006 CE/HCP4ADT Bearing Typical Application Areas
