Deep groove Ball Bearing is the most representative structure in rolling bearing, which is widely used. In addition to radial load, this kind of bearing can also be loaded with bidirectional axial load. The friction torque is small, and it is most suitable for adjusting rotation, low noise and low vibration. Bearings are widely used in automobile, electrical, instrumentation, construction machinery, agricultural machinery and various professional machinery. This kind of bearing has open and closed deformation structure.
Deep groove ball bearings consist of an inner and outer ring with a cage containing a complement of precision balls. The standard Conrad-type bearing has a deep-groove construction capable of handling radial and axial loads from either direction in versatile designs that permit relatively high-speed operation.

Craig Wenger and David Turover, designers from the United States, brought their latest design to solve the fish-draining problem: GravityFlow2 can automatically change the fish tank. 
In fact, they studied on this issue a few years ago and launched the first automatic water changing fish tank on the Kickstarter crowdfunding website, which has received a lot of support. Now this product is an improvement over the design of the year. 
As its name implies, this tank uses the principle of gravity flow of water. A glass tube is inserted into the bottom of the tank. When changing water, it is only necessary to normally inject fresh water into the tank, and the sewage will automatically follow the catheter from the water tap. Outflow. 
This approach is not only simple and convenient, but also eliminates the cumbersome and costly use of special filters. Can be described as convenient and quick, children can operate. (Source: Design)

The lazy gospel, the automatic water change tank finally came
You must have experienced such a painful moment in your home fish farming: changing water. It does not matter if all the fish and ornaments are taken out. If a special filter is used, it is expensive and cumbersome. You are in trouble. The fish are also very uncomfortable.
