Problem

In the low-temperature range in particular, problems were occurring with the sealing rings formerly used in solar parks.

Projekt

Development of new shaft sealing rings for optimal material resilience even in an extended temperature range.

Use in solar parks with huge temperature differences and changes in weather.

Requirement

Material needs to withstand the extended temperature range with 100% reliability. Test carried out solely using the lubricants provided by the customer.

Result

• Development of new shaft sealing rings with an application-specific design with multiple sealing and dust lips
• The requirement to counteract possible dirt between the flange and the transmission is met not only thanks to a second radial dust lip, but primarily also thanks to an additional axial dust lip

Advantage

Huge temperature range withstood with 100% reliability.
