7202 ACD/HCP4ADGA Bearing Product Overview & Core Advantages
The 7202 ACD/HCP4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 25° contact angle for optimal axial load capacity. Its extra light preload (Class A) ensures minimal friction and precise rotational characteristics, making it ideal for high-speed, high-rigidity applications. The use of ceramic balls and a phenolic cage contributes to its superior high-speed performance and extended service life.
7202 ACD/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7202 ACD/HCP4ADGA is decoded as follows:
- 7202: Basic series designation for a metric angular contact ball bearing with 15mm bore, 35mm OD.
- A: Denotes a 25° contact angle.
- CD: Indicates Universal Matchable (SU) design. Two bearings can be paired in a universal arrangement (back-to-back or face-to-face).
- HC: Signifies the use of Hybrid Ceramic components (ceramic balls).
- P4A: Specifies a very high tolerance class (P4A), exceeding ABEC 7 precision, for exceptional running accuracy.
- DGA: Indicates the bearing is lubricated with a specific grease suitable for the stated temperature range.
7202 ACD/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The P4A super-precision tolerance and extra light preload provide exceptional rotational accuracy and system stiffness, minimizing deflection under load.
- Enhanced Speed & Durability: The hybrid ceramic construction (steel rings with ceramic balls) reduces centrifugal forces, lowers operating temperature, and enables a very high limiting speed of 95,000 rpm. The phenolic cage is lightweight and robust, ideal for high-speed operation.
- Superior Load Capacity: The 25° contact angle is optimized to handle significant axial loads in one direction while also supporting substantial radial loads.
- Universal Matching Capability: The Universal Matchable (SU) design allows two bearings to be easily paired to accommodate combined loads from both directions, increasing application flexibility.
7202 ACD/HCP4ADGA Bearing Typical Application Areas
This high-precision angular contact ball bearing is ideally suited for:
- High-Speed Machine Tool Spindles
- Precision Grinding Spindles
- High-Frequency Machining Centers
- Dental and Medical Handpieces
- Aerospace Actuators and Control Systems
- High-Performance Robotics and Automation
