Except for this, there are also other kinds of Honeycomb Substrates such as Ceramic Honeycomb Substrate, Metallic Honeycomb Substrate, Ceramic Honeycomb Substrate Catalyst Carrier, etc. And the Honeycomb Substrates are always used as a carrier for catalyst in chemical reactions.

For a SBR Rail and Block or a TBR Rail and Block, there are many linear materials may be needed. Linear bearings are definitely one of them.
Linear bearings generally use a pad, bushing, or roller system to carry a load on a rail that need not be a straight line. The rail can be most any length, although that dimension is limited by the actuator.http://www.lsyongrun.com/tbr-rail-and-block/

A cartooning machine, sometimes called a cartoner for short, is a type of packaging machine. Its sole purpose is to form cartons. Have you ever seen a milk carton? If you look at the average milk carton in the grocery store, a cartooning machine probably made it. A cartooning machine forms cartons that stand up straight, close, are folded, side-seamed, and then, ultimately, sealed.

Axial Flow Fans date back to the horizontally configured windmills of Europe in the Middle Ages. The first electrically powered fans, introduced in the 1880s, were axial fans. Axial fans are named for the direction of the airflow they create. Blades rotating around an axis draw air in parallel to that axis and force air out in the same direction. Axial fans create airflow with a high flow rate, meaning they create a large volume of airflow. However, the airflows they create are of low pressure. They require a low power input for operation.

Slewing Bearings, or turntable bearings, are ball or roller style bearings composed of two concentric rings either of which may include a gear. This type of bearing enhances load support and power transmission in all directions, and is typically employed to support heavy loads for slow applications and large equipment such as earth excavators and construction cranes.
