[Column] Means of "Realization" Necessary for Design Engineering

[Column] Means of "Realization" Necessary for Design Engineering

In the 5th session, we will focus on the means to "realize" ideas and explain sdtech's approach to design engineering!

In the previous fourth session [“Ideas” necessary for design engineering], we explained design engineering as a means to discover “what to conceive and how to realize it” as the original upstream process of design and development. This time, we will introduce “how to realize it.” Recently, in application development required for products and services, by utilizing various tools and services, the process of prototyping what has been defined in requirements and design, and evaluating the validity of the incorporated requirements has become more efficient, although it cannot be said to be “easy.” By advancing digitization within the development team, efficiency has been improved. It is important not to eliminate the “ideas” generated in the previous process merely as theoretical discussions but to make them tangible. This allows for the identification of areas for improvement and better requirements during the concretization process, and it also enables prioritization towards “realization.” *For detailed content of the column, please refer to the related links or download the PDF. If you have any questions or concerns, please feel free to contact us.

Wearing 87 "Hallite"

Wearing 87 "Hallite"

The bearing 87 is a special composite material made of PTFE and bronze. It offers low friction for low to medium load bearings and provides contamination embedding effects!

Hallite 87 wear ring supports lateral loads and eliminates stick-slip between moving parts. It excels in heat resistance and creep resistance, making it suitable for wear rings that undergo reciprocating, oscillating, and rotating motions, regardless of lubrication. It also has the function of embedding contaminants generated within hydraulic cylinders, minimizing damage to seals and hardware. Additionally, the phenomenon of gizzarding, which can cause momentary high temperatures, often occurs in hydraulic cylinders of heavy construction machinery. The wear ring '87' functions as a buffer to prevent impact on the seals. 【Features】 ■ Low friction ■ Contaminant embedding effect ■ Excellent flexibility ■ Stepless length adjustment possible ■ Easy assembly Hallite is a group company of Michelin.
