FAQ

How do I determine the correct contact angle for my Angular Contact Ball Bearing application?

Choosing the right contact angle for an Angular Contact Ball Bearing is crucial for optimal performance. The contact angle, typically ranging from 15° to 40°, determines the bearing's axial load capacity. Lower angles (e.g., 15°-25°) are suited for applications with moderate axial loads but require high-speed rotation, such as in electric motors. Higher angles (e.g., 30°-40°) can withstand heavier axial loads, making them ideal for gearboxes or pumps. Understanding the specific operational requirements, including load type and magnitude, rotational speed, and precision needs, will guide you in selecting the Angular Contact Ball Bearing with the most appropriate contact angle.

What is preload, and why is it important in the context of Angular Contact Ball Bearings?

Preload in Angular Contact Ball Bearings refers to intentionally introducing a slight axial load during assembly to remove play between the balls and races, enhancing rigidity and precision. This is particularly important in high-precision machinery like CNC machines, where minimal backlash and high stability are required. By carefully adjusting the preload, the bearing's running accuracy and stiffness can be optimized. However, excessive preload can lead to increased friction, heat generation, and reduced bearing life. Therefore, a balanced preload setting is vital to exploit the full potential of Angular Contact Ball Bearings without compromising their longevity.
