We provide an "Oil Seal Failure Analysis Chart" that allows for the early detection of causes of oil seal leaks and failures. Requesting an investigation from manufacturers or distributors can often take time, but by using this document, it is possible to facilitate the early identification of trouble causes. We maintain a constant stock of TTO brand oil seals and can accommodate small lot deliveries. It is also possible to order types that are not currently in stock, and we will consider maintaining them as regular inventory. 【Features】 ■ Enables simple cause investigation without needing to request from manufacturers or distributors ■ Reduces costs and time associated with investigations ■ Allows for early understanding of causes of failures or malfunctions, preventing damage or breakage *You can view it immediately by clicking the download button. Please feel free to contact us with any inquiries. ★ We are also offering an "Oil Seal Manufacturer Model Comparison Chart" that is helpful for switching from the current manufacturer.

We would like to introduce GMORS's "High-Performance PTFE Coating Technology." This technology is a dry film that effectively reduces friction on the surface of sealing materials without the need for conventional liquid lubricants. The coating, which is only a few microns thick, not only alters the surface properties but also helps prevent stick-slip phenomena. Additionally, we have included past case studies in our catalog, so please feel free to download and take a look. 【Benefits of Using PTFE】 ■ Can reduce the static friction coefficient by over 70% with various types of rubber materials ■ Prevention of stick-slip phenomena ■ Improvement in friction reduces issues such as sticking, twisting, and bursting of sealing materials that occur in automated assembly lines ■ Coloring is possible, which aids in identification ★ Compliant with the Food Sanitation Act! * For more details, please refer to the PDF materials or feel free to contact us.
