Simrit, a subsidiary of Freudenberg-NOK Sealing Technologies, has introduced an advanced 75 FKM 260466 wear-resistant fluoroelastomer compound for satisfying the compatibility needs of well-known synthetic oils applied in industrial gears.
Simrit’s new FKM materials were produced in order to be used in radial shaft seals, which reacts with the aggressive oils in a wide range of industrial gearbox sealing procedures. These FKM compounds ensure comparatively superior chemical resistance and also increased temperature resistance than other common blends. With this superior resistance property of the FKM materials, it can be generally employed in a broad range of applications that contains synthetic lubricants. Whereas the pre-existing material blends reduces service life of the whole application by causing a wear and degradation of the materials, when it is used in applications containing synthetic oils.
Joel Johnson, Simrit technology’s Global Vice President, stated that there is a need for the development of a solution such that it tolerates the nature of aggressive oils, which ensures the optimum use of the superior functioning of the lubricants that are polyglycol-based in industrial gears. Johnson said that the company’s material expert team has produced a tailor-made polymer structure concentrating on the wear-resistance and stiffness of the sealing material, which overcomes the limitations of the pre-existing FKM materials.
The Simrit’s 75 FKM 260466 fluoroelastomer ensures superior level of wear resistance while in contact with the synthetic lubricants and also improves the service life of the radial shaft seals over a wide range of temperature and load. These FKM materials are tested according to the six sigma quality standards and found that they are capable of extending the service life to about 20,000 h and decreasing the down time of industrial gearbox sealing applications. These FKM materials can be processed in an injection molding process machine using a novel mixing process.
