7202 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7202 CD/P4ADGB is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a preloaded duplex set, it delivers superior performance in handling combined radial and axial loads. Manufactured to the stringent P4A tolerance class, it offers extremely tight dimensional control for critical, high-speed machinery. Its phenolic cage and optimized 15° contact angle contribute to its high-speed capabilities and smooth operation.
7202 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
The model number 7202 CD/P4ADGB provides detailed technical specifications:
- 7202: Basic series number indicating a 15mm bore, 35mm OD, and 22mm width.
- C: Denotes a 15° contact angle.
- D: Indicates the bearing is supplied as a universal matchable duplex set (DB pairing).
- P4A: Specifies the ultra-precision tolerance class, exceeding ABEC 7 standards.
- DGB: Signifies a light preload (Class B) is applied to the duplex set.
7202 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The universal matchable duplex arrangement creates a highly rigid bearing system capable of supporting significant combined loads from any direction without requiring selective mounting.
- High-Speed Performance: The lightweight phenolic resin cage ensures stability and low friction at high rotational speeds, with a limiting speed of 95,000 rpm. The 15° contact angle provides an optimal balance between radial and axial load capacity for high-speed applications.
- Ultra-Precision: Manufactured to P4A tolerance class with extremely tight bore, OD, and width tolerances, this bearing guarantees minimal runout and vibration for superior operational accuracy.
- Preloaded for Immediate Use: The bearings are supplied with a light preload (DGB), eliminating internal clearance and ensuring immediate high-stiffness performance upon installation, which is critical for spindle applications.
7202 CD/P4ADGB Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Equipment
- Robotic Arm Joints and Drives
- Medical and Dental Handpieces
