Wear rings widely used in hydraulic cylinders and similar applications. Among them, the wear rings used in the rod section were primarily foreign-made due to concerns about stick-slip. Therefore! Focusing on sliding properties, wear resistance, and impact resistance, a new domestic wear ring made from new materials has been developed. We can produce small lots in standard sizes from other manufacturers. Custom sizes are also available. We offer high-quality, domestically produced wear rings with short lead times.

• Hydraulic Equipment

Achieving the shortest delivery time in the industry! O-rings, Koyama, and Koban, used in semiconductor liquid crystal manufacturing equipment and various large devices, often come in non-standard large diameter sizes and are produced using a joining method commonly referred to as "supply baking." The joints in the "supply baking" method are vulcanized together without any unvulcanized sections, resulting in properties equivalent to a seamless O-ring. While it typically takes over a month to manufacture different sizes individually, our company can produce them in a standard delivery time of 2 to 3 weeks, and as quickly as 1 week at the shortest. If you specify the shape, material, wire diameter, and inner diameter, we can accept orders starting from just one piece.

The "FS Seal" is a seal that incorporates a garter spring into a thin sheet of specially formulated PTFE (filled tetrafluoroethylene resin) that has been processed through a die. This design enhances the elasticity of the seal lip. By isolating the spring from the fluid, it exhibits the excellent properties of filled tetrafluoroethylene resin, such as heat resistance, cold resistance, freeze resistance, and chemical resistance. Since it does not use rubber, it can accommodate a wider range of pressure and temperature compared to conventional rubber seals. It is effective in various applications such as mixers, compressors, pumps, blowers, and food machinery. 【Features】 ■ Excellent follow-up capability to shaft eccentricity ■ Minimizes wear torque values under high pressure ■ Heat resistance of 260°C and cold resistance of -60°C *For more details, please refer to the materials.

Zetpole, or "H-NBR (Hydrogenated Nitrile Rubber)," was developed as an improved grade of NBR and excels in temperature, fuel, ozone, and abrasion resistance, making it widely used in various industries, particularly the automotive industry. Ourex has standardized oil seals made from Zetpole, focusing on these properties. Compared to NBR (Nitrile Rubber), Zetpole offers higher mechanical strength and chemical stability, along with improved durability, heat resistance, cold resistance, and fuel oil resistance. When used in products, it is expected to enhance compression set resistance, heat generation, and abrasion resistance. When used as an oil seal, it can improve heat resistance by 10-15 degrees, contributing to a longer lifespan within conventional temperature ranges. It is anticipated that some areas can be replaced by fluororubber, which was previously over-spec. Additionally, it possesses excellent mechanical strength, particularly in high-pressure and wear-prone sliding parts, making it ideal for pressure-resistant oil seals. It also complies with food sanitation laws and has a track record of being used in food mixers. Furthermore, one of Zetpole's features is its high resistance to alternative refrigerants, including HFCs, making it promising for use as a sealing material for refrigerants.

"Serbic EPP" is a new material that combines traditional synthetic fiber substrates and phenolic resin with solid lubricants to enhance "ductility," "toughness," "impact resistance," and "sliding properties." Among these, it particularly excels in sliding properties, making it usable as a rod-side bearing, which was not possible with conventional materials. Additionally, it also possesses vibration-damping capabilities concerning lateral load resistance. It is suitable for applications such as oil pneumatic wear rings, sliding rings, and sliding components. 【Features】 ■ It is a material that combines synthetic fiber substrates, phenolic resin, and solid lubricants. ■ Due to the low absorption rate of synthetic fibers, it has minimal swelling, resulting in excellent dimensional stability. ■ Compared to conventional products (cotton fabric and phenolic resin), it has greater elongation and higher impact strength. ■ The combination of high toughness and high impact resistance makes it less prone to chipping. ■ It is combined with solid lubricants, allowing it to be used as a maintenance-free bearing material. ■ Custom dimensions that are not limited to standard manufacturer sizes can also be produced. *For more details, please contact us or download the catalog.
