7209 BECBY Bearing Product Overview & Core Advantages
The 7209 BECBY is a single row angular contact ball bearing designed for applications requiring high precision and reliable performance under combined loads. This precision bearing excels in handling significant axial loads in one direction alongside radial loads, thanks to its optimized 40° contact angle. Manufactured to P6 (ABEC-3) tolerance class, it offers superior running accuracy and dimensional stability. Its compact design with a 19 mm width makes it ideal for space-constrained, high-performance assemblies.
7209 BECBY Bearing Model Code Explained, Specifications & Naming Convention
The model number 7209 BECBY is decoded as follows:
- 7209: Basic series designation (45 mm bore, 85 mm OD)
- B: Denotes a 40° contact angle
- E: Represents an optimized internal design for enhanced load capacity
- CB: Indicates normal internal clearance and specific manufacturing standards
- Y: Signifies a brass cage, suitable for high-speed operation
7209 BECBY Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 40° contact angle is engineered to support substantial combined radial and axial loads efficiently. The robust brass cage ensures stable ball guidance under demanding conditions.
- High-Speed Performance: The brass cage (Y suffix) and precision-ground components contribute to excellent high-speed capabilities, with a limiting speed of 10,000 rpm.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional controls on bore, outside diameter, and width, ensuring predictable performance and ease of installation in precision machinery.
- Durability & Compliance: Constructed from chrome steel for both rings and balls, offering high wear resistance. The bearing is pre-lubricated and compliant with ROHS and REACH standards.
7209 BECBY Bearing Typical Application Areas
