S7002 ACE/HCP4A Bearing Product Overview & Core Advantages
The S7002 ACE/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional speed and rigidity. Engineered to simultaneously handle combined radial and axial loads, this metric-series bearing features a compact design with a 15 mm bore. Its key advantages include superior high-speed performance enabled by a phenolic cage and ceramic balls, and outstanding operational reliability due to its sealed, pre-lubricated, and preloaded configuration. It is an ideal solution for high-reliability and high-precision machinery.
S7002 ACE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S7002 ACE/HCP4A decodes the bearing's specific technical features as follows:
- S7002: Denotes the bearing series and size (15mm bore, 32mm OD).
- A: Indicates a 25° contact angle, optimized for high axial load capacity.
- C: Signifies that the bearing is supplied with a preload for enhanced rigidity and precise rotational accuracy.
- E: Designates the use of ceramic (hybrid) balls for reduced weight, lower friction, and higher speed capability.
- HC: Stands for a phenolic (resin) cage, which is lightweight and ideal for high-speed operation.
- P4: Corresponds to the P4 (ABEC-7) tolerance class, indicating ultra-high precision.
- A: Confirms the bearing is supplied pre-lubricated.
S7002 ACE/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single, preloaded arrangement and P4 tolerance class ensure minimal deflection and exceptional running accuracy, providing a stable and rigid support for spindles and shafts.
- Superior High-Speed Capability: The combination of a lightweight phenolic cage and low-density ceramic balls significantly reduces centrifugal forces, enabling a high limiting speed of 75,000 rpm.
- Excellent Load Capacity: The 25° contact angle is optimized to handle significant combined loads, offering robust performance under complex loading conditions.
- Long-Term Reliability & Low Maintenance: As a sealed and lubricated unit, the bearing is protected from contamination and is ready for immediate use, ensuring long service life with minimal maintenance.
