In today's article we present a special innovative solution in the field of elastomers, the material 75FKM 260466. It is a new fluorine rubber compound FKM, developed by our partner Freudenberg Sealing Technologies, whose special formulation extends the life expectancy of the seal very significantly. It is a much more resistant material compared to synthetic oils, especially polyglycols and biodegradable lubricants, which have a critical impact on seal life expectancy, raceway wear and axle marking.

Comparison of the new elastomer vs. other standard elastomers
This new formulation will enable our customers, in particular our motors and gearboxes manufacturers, reduce the total imputed costs over the life of the seal. This significant advantage is visualized in the following table, where all the imputed costs throughout the product life cycle are compiled. The data for the new composite 75FKM 260466 for elastomer we compared them with the standard compound 75FKM 585.
The conclusions that can be drawn after analyzing the data shown in the table are as follows: despite the higher acquisition cost of the new compound, the sum of total costs (direct and indirect) is lower. This decrease in the total cost is due to reduced energy consumption and the need for more spaced maintenance intervals, which allow for a more efficient use of energy. save up to 20% the cost of intervention on the machine.
Advantages of the new elastomer compound
The already existing advantages of standard FKM (75FKM 585) over materials from other manufacturers have been further enhanced by the development of the 75FKM 260466, wear-resistant for synthetic oils. With the use of this new elastomer compound, our customers have differential elements that allow them to gain in competitiveness:
- - Increased life expectancy by 80%
- - Reduced wear of the friction track width by up to 70%
- - Reduction of shaft marking to 90%.
Comparison of wear of the new elastomer vs. other elastomers
The following table shows a comparison of the friction track width wear between the standard FKM, the 75FKM 260466 and an FKM compound from a major competitor.
Since its launch, this new compound 75FKM 260466 has been steadily being incorporated into the standard range of seals. At present, is available from permanent stock in more than 200 different dimensions, for shafts from 15 to 120 mm.. In addition, approximately 60 references can be manufactured to order at short notice.
