7204 BECBY Bearing Product Overview & Core Advantages
The 7204 BECBY is a single row angular contact ball bearing engineered for high-performance applications requiring precision and reliability. This precision bearing is designed to accommodate combined loads, specifically handling significant axial loads in one direction alongside radial loads. Its optimized 40° contact angle and P6 (ABEC-3) tolerance class ensure high running accuracy and operational stability, making it an ideal choice for demanding, high-speed machinery.
7204 BECBY Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7204 | Standard bearing series designation, indicating a metric 20mm bore, 47mm OD, and 14mm width. |
| BE | Designates a 40° contact angle, optimized for high axial load capacity. |
| CB | Indicates a brass cage (machined window type), which provides high strength, excellent guidance, and suitability for high-speed operation. |
| Y | Signifies that the bearing is pre-lubricated with a specific grease, offering ready-to-use convenience and initial protection. |
7204 BECBY Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated raceway curvatures are engineered to handle high axial loads efficiently while maintaining excellent high-speed performance.
High-Speed Capability: The robust brass cage (CB) ensures stable ball guidance and low friction, contributing directly to the high limiting speed of 19,000 rpm. The open design facilitates efficient lubrication management.
Precision and Rigidity: Manufactured to a P6 (ABEC-3) tolerance class, this bearing guarantees precise shaft positioning and smooth operation. The single row design with a large contact angle provides high rigidity for the supported arrangement.
Durability and Material Quality: Constructed from high-grade chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance, suitable for a wide temperature range from -30°C to 110°C.
7204 BECBY Bearing Typical Application Areas
The 7204 BECBY is ideally suited for applications requiring high precision, speed, and axial load capacity. Key industries and machinery include:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers.
- High-Frequency Electric Motors and Spindles: Where rapid acceleration and deceleration are common.
- Pumps and Compressors: Particularly in stages handling significant thrust loads.
- Precision Gearboxes and Drive Systems: For accurate power transmission with minimal deflection.
