For the development of the innovative Gerromatic G 61 our engineers have taken nature as a role model. The special design of the sealing lip distributes the pressure, so that a wider contact zone for the fluid film between the shaft and sealing lip is used. The benefits for the process industry are better friction, less wear and a low heat generation, which extends the lifetime of the seal.
75 FKM 260466
The material innovation of Freudenberg Sealing Technologies for industrial gear units is called 75 FKM 260466. This especially wear-resistant material made of fluoro rubber has been especially developed for use in synthetic oils, especially polyglycols (PGs).
These lubricants are used in power transmission aggregates, such as worm gears, for various reasons.
With the coordinated combination of 75 FKM 260466 and PGs, the challenges of sealing edge wear and shaft inlet can be mastered and operating life increased compared to other seal materials.
As integrated solutions, Sealing Modules have the advantage of using fewer components, offering easier installation, reducing weight and saving space.
The BlueSeal design and its low friction PTFE POP® lip are based on long experience with the PTFE Simmerring®. The weight savings of 40% and an installation space reduced by 50% support future requirements for emissions reductions.
The Contact Minimized Simmerring® (CMS) delivers greater durability with less friction for the small shaft diameters, 5-20 mm, typically found in sensor, actuator, pump and throttle applications.
The Energy Saving Seal® (ESS) minimizes friction on the crankshaft and camshaft and in transmissions. This significantly reduces fuel consumption and emissions. The reduction of friction also extends the seal’s operating life while increasing the machine’s reliability.
Cassette Seals consist of a Simmerring® and an optimized wear sleeve (either hard or soft unitized). They are used to seal shafts in heavy construction and agricultural equipment that, for example, are exposed to high stresses. They also effectively protect engines, transmissions, differentials and axles against dirt, water and other environmental influences. The latest developments in elastomers also make it possible to achieve optimal sealing without a spring. This reduces friction even at high temperatures. Combi seals consist of a Simmerring® (individual or double lip) and a polyurethane wiper. They increase the protection against external contaminants while allowing axial and rotary movement.

The low-friction Simmerring® (LFS) is a combination of advanced, high-performance and friction-optimized ACM materials.
Lube & Seal
The customer benefits all around when – and only when – the seal and the lubricant work in perfect harmony – with friction-free processes, cost-effective systems, and market-driven solutions. Based on this insight, Freudenberg Sealing Technologies and the Freudenberg Group’s Klüber Lubrication have bundled their ground-breaking know-how to create Lube & Seal, an innovative sealing system from a single source.
The PTFE POP® seal (= Power Optimized PTFE) demonstrates its robustness as a PTFE Simmerring® by adjusting material and geometric characteristics for minimal friction.
Simmering & Encoder
The combination of a Simmerring® with an integrated encoder not only seals the shaft reliably but captures its rotational speed as well. The collected data are fed into the engine control unit, allowing the optimization of the combustion process. The result: less fuel consumption and lower emissions. Other advantages include a reduction in the number of components and in the size of the installation space, along with easier mounting and a decrease in weight.
