Freudenberg-NOK Merkel has announced its new Merkel Radiamatic R 55 radial shaft sealing ring. According to the company, the R 55 has been designed with an integrated deflector lip that protects wind turbine systems against harsh environment elements and eliminates the need to use a second seal.
In addition, the company says its engineers were able to effectively counter the risk of increased wear due to vacuum formation between the sealing and the deflecting lips through the use of lip texture, thus helping ensure that ample initial grease lubrication for the deflecting lip remains in the space between the seal lips.
