NAK has always been a front runner in the industry to develop seals for futuristic technologies. This has helped us to design and develop seals for the E-World. NAK clearly understands the sealing needs of e-Mobility motors. Electric motor seals in an electric motor are an essential component to keep the system dry and allow oil lubrication of the gearbox. An electric motor seal must be designed to withstand the dry conditions in an electric motor while still being able to accommodate the necessary of oil lubrication for a gearbox that can run at speeds up to or over 10,000 rpm. In e-mobility, these two diametrically opposite conditions in the same application must be kept completely separated by the e-mobility seal. NAK has developed a special lip design that can handle both conditions by providing an excellent sealing function, reducing friction and improving the energy efficiency of the mechanism. The main lip is designed to maintain a tight seal as well as minimize friction caused by a motor operating at high speeds in drier conditions. NAK’s electric motor seal is manufactured with an advanced rubber formula (FKM, PTFE) to meet the demands of high speeds and a wide range of temperatures.

Rotary Seals are often referred to as radial shaft seals, rotary shaft lip seals, or oil seals and so on. The main function of the rotary seal is to protect the system from dirt, dust, water and other contaminants, retain the lubricant in system. NAK’s research and development team has more than 45 years of experience in design and manufacture of seals. NAK uses cutting edge technology to support OE customers. NAK sources its raw materials from world leaders in the field from around the world, including America, Japan and European countries. These high grade materials helps in making seals with very specific and important properties such as wear resistance, oil & fluid resistance and chemical resistance which are key to the functioning and life of the seal. The most common rubber materials are NBR, HNBR, FKM, ACM, VMQ etc. NAKs R&D and in house materials laboratory team have successfully created customized rubber compounds for very specific customer requirements through our StreamSyn Sealing Solutions.

High pressure seals are essential to a pump’s functioning and service life. High pressure seals must withstand a high internal pressure, while preventing hydraulic oil leakage. The seal must also be able to keep contaminants such as water and dust from entering the system. High quality seals provided by NAK can extend the pump’s service life. NAK supplies seals for all different kinds of pumps, including piston, gear, vane, vacuum and submersible pumps. NAK can also customize the seals to meet a customer’s exact specifications. Due to our special structural design, our advanced high pressure seals can withstand pressures of up to 15bar.

There are two main types of hydraulic rod seals: composite seals, and u-cup seals. Hydraulic rod seals prevent fluid from leaking out of the cylinder so as to maintain the fluid pressure necessary to facilitate the movement of the piston. The rod has a buffer seal that supports the rod seal and prevents leakage under pulsing spike-pressure during heavy-loading of the hydraulic cylinder.
