• Sealing

A certain raw materials manufacturer has announced that it will withdraw from PFAS production by the end of 2025. It is expected that the withdrawal of this manufacturer will lead to a serious shortage of materials in the market. In fact, we have seen an increase in inquiries from our customers about products that use manufacturers other than this particular raw materials supplier. This catalog introduces the 'O-Rings (Buna-N, FKM, Fluoroelastomer)' from GMORS, which is handled by Seiwa Shokai Co., Ltd. By purchasing GMOS O-Rings from us, we believe we can help alleviate future supply concerns. [Reasons for Feasibility] - GMOS sources its products from suppliers other than the aforementioned raw materials manufacturer. - We are able to manage inventory, so if you provide us with information, we can prepare for immediate delivery. [Customer Feedback] - It has led to a reduction in costs from current purchase prices. - Since they hold inventory, there is no longer worry about the availability of materials in the market. *For more details, please refer to the PDF document or feel free to contact us.

Company A has been supplying products to users in the semiconductor industry. Among the products for users, FFKM material O-rings from overseas manufacturers are being used. Although an order was placed with the supplier (Company B), we received a response stating, "Orders in small lots are not possible, and even if we can accept the order, the delivery time will be over a year." As a result, we were contacted by your company, and we proposed a replacement by asking for the current material number and manufacturer. At the same time, we suggested that the users conduct tests. [Case Summary (Partial)] ■ Issues - An order was placed with the supplier (Company B), but it will not meet the user's delivery schedule. - Orders in small lots are not possible, and we cannot hold excess inventory. ■ Proposal - Replacement products for the materials currently used by the users. - We would like the users to conduct tests before adoption. *For more details, please refer to the PDF document or feel free to contact us.

Recently, we have been receiving more inquiries about wanting O-rings made from materials that comply with the Food Sanitation Act and have FDA certification. At GMORS, the company we represent, we can provide materials that have obtained Food Sanitation Act and FDA certification in NBR (nitrile), FKM (fluoroelastomer), silicone, and EPDM. We have compiled examples of proposals for our customers into a PDF document. Please take a look at the PDF, and if you have any concerns, feel free to contact us.

• Other optical parts

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.

• Coating Agent

Components such as "O-rings," "packings," and "gaskets" belong to the category collectively referred to as "seals." "Seals" are a general term for parts and devices that prevent foreign substances from entering and fluids from leaking out. Although sealing materials are consumables, they play an important role in factories and daily life. The O-rings (made of EPDM, silicone, and NBR) from GMORS, which we handle at Seiwa Shokai, comply with food sanitation laws and can be used in food processing machinery and food packaging machinery. If you are having trouble understanding how to choose seals for specific applications, please feel free to contact us. We are currently offering a seal product selection chart. *For more details, please refer to the PDF materials or feel free to contact us.

By assembling the bearings under strictly managed preload conditions, there is no play in the roller. 【Features】 ■ Equipped with high-precision miniature ball bearings ■ Achieves reduction in friction torque ■ Bearings are assembled under strictly managed preload conditions ■ No play in the roller ■ Suitable for small transport devices *For more details, please refer to the PDF document or feel free to contact us.
