The suggestion you mentioned about shortening the assembly time is very accurate. Typically, to assemble a rack-and-linear-guide system, a linear guide is mounted on one side, while the rack is installed on the opposite side. To bring the system to its optimal operating condition, it must be managed and assembled by technically experienced personnel. However, I have noticed that you may not yet be fully aware of the technical advantages of FDH products. Therefore, I would like to share the following key information: The uniqueness of the gear design: FDH products do not employ a conventional gear structure; instead, they are designed based on the principle of the hypocycloid curve. This design significantly reduces noise during high-speed operation while achieving a low friction coefficient of 0.005, allowing it to function normally without lubrication. Furthermore, this product minimizes the polygonal effect commonly found in racks and chains, resulting in zero backlash and no cumulative error. Its positioning accuracy can reach 0.03 mm, delivering outstanding performance. A variety of material options are available: the rail body can be manufactured from aluminum alloy, steel, stainless steel, and other materials. This makes the product highly versatile, allowing for optimized solutions tailored to different environments and applications. Furthermore, the FDK circular system developed based on this technology not only inherits all the advantages of the FDH linear system but also significantly enhances the precision and durability of circular motion through optimized design. The FDK system can effectively deliver high-precision circular motion solutions in a wide range of industrial environments.
