Bearings and seals for industrial equipment

The area of competence includes the understanding and analysis of the bearing and sealing tasks of rotating and oscillating machine parts in almost all areas of industry. This includes the appropriate selection of elements to suit the installation environment, as well as the exploration of the cause of failures. A closely related topic is to clarify the lubrication task precisely, to prioritise environmentally friendly lubricants, and to modify an existing bearing and sealing system to bring it in accordance with an environmentally friendly solution to the greatest extent possible.
