Le 7205 Angular Contact Ball Bearing is a high-precision bearing designed to handle combined radial and axial loads, making it ideal for high-speed and high-accuracy applications. With its contact angle design, it can support axial loads in one direction while maintaining excellent rotational stability.
Manufactured from premium chrome steel and available in stainless steel and ceramic variants, the 7205 bearing delivers high rigidity, low friction, and excellent performance under demanding operating conditions. It is commonly used in pairs or sets to support bidirectional axial loads in machine tool spindles and precision equipment.
With its optimized internal structure, the 7205 angular contact bearing ensures smooth operation, reduced heat generation, and long service life, making it suitable for high-speed industrial environments.

FAQ
Q1: What is the main difference between angular contact and deep groove ball bearings?
A: Angular contact bearings are designed to handle combined loads, especially axial loads, while deep groove ball bearings mainly support radial loads.
Q2: Can 7205 bearings be used in pairs?
A: Yes, they are often mounted in pairs (back-to-back or face-to-face) to support axial loads in both directions.
Q3: Do you offer ceramic or high-precision versions?
A: Yes, we offer ceramic and precision-grade versions such as P5 and P4 for high-speed applications.
