7006 ACD/P4AQBCA Bearing Product Overview & Core Advantages
The 7006 ACD/P4AQBCA is a precision quadruplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This P4A tolerance class bearing is configured in a back-to-back (QBC) arrangement, providing superior stability and the ability to withstand combined radial and axial loads from multiple directions. Its compact design, featuring four matched bearings, offers an ideal solution for high-precision, high-rigidity spindles and other critical machinery components where uncompromising performance is essential.
7006 ACD/P4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD). |
| AC | Angular Contact design with a 25° contact angle. |
| D | Indicates a duplex (two-bearing) set. In this context, it is part of a larger matched set. |
| /P4A | Specifies a high-precision tolerance class (P4A), exceeding ABEC 7 standards for superior running accuracy. |
| QBC | Denotes the Quadruplex Back-to-Back matched arrangement of four bearings. |
| A | Signifies an Extra Light preload for minimal friction and optimal high-speed operation. |
7006 ACD/P4AQBCA Bearing Structural Features & Performance Benefits
Unmatched Rigidity and Load Capacity: The quadruplex back-to-back (QBC) arrangement creates a highly rigid bearing system that effectively resists moment loads and provides exceptional stability. This configuration allows the bearing set to handle significant combined radial and axial loads.
High-Speed Performance: The phenolic resin cage is lightweight and robust, contributing to lower centrifugal forces and smooth operation at the high limiting speed of 53,000 rpm. The 25° contact angle is optimized for high-speed applications requiring good axial load capacity.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, this bearing ensures minimal runout and superior rotational accuracy for precision machinery.
Optimized for Performance: The bearing is pre-lubricated and features an open seal type, making it ready for integration into systems with centralized lubrication, ensuring long-term, reliable performance within its specified temperature range.
