7210 BECBY Bearing Product Overview & Core Advantages
The 7210 BECBY is a single row angular contact ball bearing engineered for precision applications requiring high rigidity and accurate rotational performance. Designed to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 40° contact angle optimized for substantial axial load capacity in one direction. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy, making it ideal for high-speed spindles and precision machinery where reliable performance and dimensional stability are critical.
7210 BECBY Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| BE | Increased internal clearance and contact angle | Optimized for preload conditions and higher axial loads |
| CB | Specific internal design and clearance | Enhanced operational stability and load distribution |
| Y | Special cage design or material | Brass cage provides excellent strength and guidance at high speeds |
7210 BECBY Bearing Structural Features & Performance Benefits
High-Precision Construction: Manufactured from chrome steel with P6 tolerance class, ensuring minimal runout and vibration for precision applications. The single row design with optimized raceway geometry provides exceptional rotational accuracy.
Superior Load Capacity: The 40° contact angle enables high axial load carrying capacity in one direction while maintaining substantial radial load capability. With a dynamic load rating of 9000 lbf and static load rating of 6975 lbf, this bearing handles demanding combined load conditions effectively.
High-Speed Performance: The brass cage ensures stable operation at the limiting speed of 9,000 rpm, providing excellent guidance and reduced friction. The open design allows for efficient lubrication management in high-speed applications.
Precision Dimensions: Features tight dimensional tolerances with bore diameter tolerance of -0.01mm to 0 and outside diameter tolerance of -0.013mm to 0, ensuring precise fit and alignment in critical assemblies.
