Sealing Solutions for General Industrial

The capabilities and reliability of rolling bearings are in large part determined by the materials used to manufacture the individual components. Rolling bearing cages are subjected to mechanical stress exerted by friction, tugging and inertia forces. In addition, there may be chemical effects due to certain lubricants or additives, organic solvents or coolants. The significance of the individual properties also depends on the operating conditions such as a humid environment, higher temperatures, impact loads or combinations of these. Seals integrated in rolling bearings may considerably affect the performance and reliability of a bearing as well. The seal materials must be resistant against oxidation (aging), wear and chemicals across a wide temperature range. With a wealth of experience in materials engineering and the respective seals and elements Parker Prädifa helps ensure that bearing deliver smooth performance.

Electric motors can be found practically anywhere today. In industrial environments, electric motors are used to drive machines and forklift trucks but also for controlling industrial robots and cranes. Commuter and subway as well as many long-distance trains are powered by electric motors, too.

In addition to long maintenance intervals, service life and robustness, efficiency is a key requirement. Maximum output combined with minimal energy consumption is a focal point in development, not only with respect to energy consumption but also in terms of design size and weight. The higher a motor’s power-to-weight ratio is the smaller is its possible design. To achieve this, the subcomponents of a motor such as bearings, guides and seals should operate with low friction in order to avoid excessive losses in an electric motor’s drive energy. With many years of experience in the development of low-friction and energy-efficient sealing systems and the requisite materials Parker Prädifa offers suitable solutions for use in electric motors.

Industrial transmission systems are used in practical all industrial areas and come in all conceivable sizes and forms. They have to meet extremely diverse operating requirements and operating conditions. Irrespective of the sector in which they are used, all industrial transmissions must operate as reliably and efficiently as possible and the diversity of transmission solutions in industrial applications makes maximum demands on the development and manufacturing expertise of the producers. At the same time, this diversity spawns an enormous range of operating conditions and thus influences the selection of sealing materials and geometries to be considered. In the absence of universal rules for the selection of the suitable type of seal for a particular application, Parker Prädifa offers expert assistance in selecting the seal best suiting the respective application.
