7032 ACD/P4ADBB Bearing Product Overview & Core Advantages
The 7032 ACD/P4ADBB is a precision duplex back-to-back angular contact ball bearing designed for applications requiring exceptional rigidity and accuracy. This P4A tolerance class bearing is preloaded and matched as a set to deliver superior performance under combined radial and axial loads. Its light preload (Class B) and optimized 25° contact angle make it ideal for high-speed, high-precision spindles and machinery where rotational accuracy and system stiffness are critical.
7032 ACD/P4ADBB Bearing Model Code Explained, Specifications & Naming Convention
- 7032: Basic designation indicating a 160 mm bore and 240 mm outside diameter.
- AC: Angular Contact design with a 25° contact angle.
- D: Signifies the bearing is part of a Duplex (matched) set.
- P4A: Denotes an ultra-precision tolerance class exceeding ABEC 7 standards, ensuring minimal runout and vibration.
- DBB: Specifies the Duplex Back-to-Back mounting arrangement, which provides high moment rigidity and excellent operational stability.
7032 ACD/P4ADBB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back (DBB) configuration creates a rigid bearing system capable of withstanding significant combined loads and moment loads. With a dynamic load rating of 66,600 lbf and static load rating of 93,375 lbf, it offers robust performance in demanding conditions.
Precision & High-Speed Performance: Manufactured to P4A tolerance class with a phenolic resin cage, this bearing ensures minimal vibration and can achieve a limiting speed of 11,000 rpm. The light preload minimizes deflection at high speeds while maintaining accuracy.
Material & Construction: Both rings and balls are made from high-grade chrome steel for durability and long service life. The open design allows for customized lubrication schemes to optimize performance for specific applications.
