How do Angular Contact Ball Bearings reduce friction and energy loss?

Compared to traditional deep groove ball bearings, Angular Contact Ball Bearings are designed to have a steeper contact angle between the bearing ball and the inner and outer rings, usually 15 or 25 degrees. This design optimizes the contact conditions between the bearing ball and the inner and outer rings and reduces sliding friction on the contact surface. Deep groove ball bearings have a smaller contact angle and are more prone to sliding friction, but Angular Contact Ball Bearings can effectively reduce this friction, thereby reducing energy loss.

Angular Contact Ball Bearings can distribute loads more effectively. They are designed to withstand a combination of radial and axial loads, and compared to bearings that only withstand radial loads, Angular Contact Ball Bearings can distribute the load more evenly to each contact point. This optimized load distribution not only reduces stress concentration on a single contact point, but also reduces the friction between the rolling element and the inner and outer rings, thereby reducing energy loss.

The preload design of Angular Contact Ball Bearings also plays a key role in reducing friction and energy loss. During installation, the clearance inside the bearing can be adjusted by appropriate preload. Proper preload can effectively reduce the internal clearance of the bearing, thereby reducing the small relative movement between the ball and the inner and outer rings, thereby reducing friction and energy loss.

Bearing material and lubricant selection are also important factors affecting friction and energy loss. Selecting high-quality bearing steel materials and appropriate lubricants can reduce friction inside the bearing and improve bearing efficiency and life. Good lubricants can effectively reduce the friction coefficient and reduce energy loss during bearing operation.

Optimized sealing and protection systems are also crucial to reducing friction and energy loss. An effective sealing system can effectively prevent external dust, contaminants and moisture from entering the bearing, keeping the lubricant clean and performing. This not only helps to maintain bearing operating efficiency, but also reduces friction and energy loss caused by contaminants, thereby extending the service life and reliability of the bearing.
