7006 ACD/P4ATFTC Bearing Product Overview & Core Advantages
The 7006 ACD/P4ATFTC is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rigidity and accuracy. This bearing is supplied as a matched triplex set in a Face-to-Face (TFT) arrangement, providing superior stability and the ability to handle combined loads (radial and axial). Manufactured to P4A tolerance class and featuring a phenolic cage, it is engineered for high-speed operation and demanding industrial environments where high rigidity and precise rotational accuracy are paramount.
7006 ACD/P4ATFTC Bearing Model Code Explained, Specifications & Naming Convention
The model number 7006 ACD/P4ATFTC is decoded as follows:
- 7006: Standard bore (30 mm) and outside diameter (55 mm) designation.
- ACD: Angular Contact design with a 25° contact angle.
- P4A: Denotes a high-precision tolerance class, exceeding ABEC 7 standards, for minimal runout and vibration.
- TFT: Indicates the bearing is part of a Triplex Face-to-Face matched set of three bearings.
- C: Specifies a Moderate preload (Class C) for optimal stiffness and rotational accuracy.
7006 ACD/P4ATFTC Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The triplex Face-to-Face (TFT) arrangement creates an exceptionally rigid bearing system, ideal for applications where shaft deflection must be minimized.
- Combined Load Capacity: The 25° contact angle is optimized to support significant radial loads and axial loads in both directions simultaneously.
- High-Speed Performance: The lightweight phenolic resin cage ensures smooth operation, reduced centrifugal forces, and a high limiting speed of 53,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance standards, this bearing guarantees precise running accuracy, low noise, and minimal heat generation.
- Durability: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and long service life.
7006 ACD/P4ATFTC Bearing Typical Application Areas
This high-precision, high-rigidity bearing set is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Industrial Pumps & Compressors
- High-Frequency Spindles for PCB drilling and routing.
- Robotic Arm Joints and Precision Gearboxes.
- Other advanced machinery requiring matched bearing sets for maximum system performance.
