"Lubricant and Radial Shaft Seal in Perfect Harmony" by Freudenberg Sealing Technologies GmbH & Co. KG

Together, shaft seals and industrial gears form complex tribological systems. The quality of the seals in such applications depends heavily on the compatibility of the radial shaft seal and the lubricant. The influence of the lubricant on the elastomer and sealing lip in a Simmerring(R) radial shaft seal is vital in this regard. It is important that the combination of elastomer and lubricant, both of which differ greatly in terms of their chemical composition, ensures low friction, low wear, and high compatibility. These tandem functions in turn determine other factors such as service life, machine availability, maintenance and the impression of quality. In other words, they influence a machine operator’s impression of the gear supplier. Nevertheless, radial shaft seals and lubricants are only C-parts in terms of development and procurement. However, it is also true to say that the functional reliability of these parts, which form a complex tribological system, are a decisive factor in terms of the functionality and service life of aggregates. You could say that these C-parts are of A-part importance.

Freudenberg Simrit, the world’s leading manufacturer of Simmerring radial shaft seals, and Klüber Lubrication, developer and manufacturer of special lubricants, have joined forces and pooled expertise to come up with “Lube & Seal”, a comprehensive technological service. With Lube & Seal, Freudenberg Simrit and Klüber Lubrication offer companies development partnerships, the aim of which is to develop complete tribological solutions featuring radial shaft seals and lubricants that have been adapted to suit each other perfectly. And all of this from a single source. This means that for the first time ever, developers and constructors of power transmission engineering and their procurement staff can use Lube & Seal to get highly effective, tested complete systems comprising both radial shaft seals and special lubricants. Radial shaft seal specialists from Simrit and lubricant experts from Klüber work together in a team to offer customers an all-round tribological system service. The Freudenberg Group assumes responsibility for providing a system solution for the problem at hand. The advent of Lube & Seal means that the days when lubricant manufacturers and sealing manufacturers laid the blame for faults at each others’ doors are gone. This is unique on the market. Thanks to Lube & Seal, significant improvements are being made in terms of the reliability and durability of machines and aggregates. Such solutions at critically important sealing points makes it easier for drive system manufacturers to make claims about guarantees.
