7204 ACD/P4A Bearing Product Overview & Core Advantages
The 7204 ACD/P4A is a single-row angular contact ball bearing designed for high-precision and high-speed applications. Engineered to accommodate combined loads, it primarily handles substantial axial loads in one direction while supporting radial loads. Its P4 (ABEC-7) tolerance class ensures exceptional running accuracy, making it ideal for applications demanding superior rotational performance and rigidity. The phenolic cage and optimized internal geometry contribute to its high-speed capabilities and smooth operation.
7204 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
- 7204: Basic series number (20mm bore, 47mm OD).
- AC: Angular Contact design with a 25° contact angle.
- D: Signifies a high rigid phenolic resin cage.
- P4A: Denotes P4 (ABEC-7) tolerance class with specific internal running accuracy requirements.
7204 ACD/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The single-row angular contact design, combined with a phenolic cage, provides excellent dimensional stability and reduces vibration at high speeds, ensuring high rigidity and precise shaft guidance.
Superior Load Capacity: With a 25° contact angle, this bearing is optimized to handle significant axial loads in one direction alongside radial loads, offering reliable performance under combined loading conditions.
High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, enabling a high limiting speed of 48,000 rpm. This makes it suitable for demanding high-speed spindle applications.
Pre-Lubricated for Immediate Use: The bearing comes lubricated and is ready for installation, facilitating quick assembly and initial operation.
7204 ACD/P4A Bearing Typical Application Areas
The 7204 ACD/P4A is ideally suited for high-performance machinery requiring precision and speed, including:
- Machine Tool Spindles
- High-Speed Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Medical and Dental Equipment
