    The Move to Water Pays for Norway's Raanaasfoss Hydro Plant Operator

    Jun 17, 2019
    The water-lubricated SXL turbine guide bearings Thordon installed as part of the re-powering of Norway’s Raanaasfoss 1 hydro plant have experienced almost zero wear after 23,887 hours of continuous operation on the first installed unit. During routine inspections of the 13.5 MW turbines, commissioned by Voith Hydro in 2013, the guide bearings – the operator’s first experience with water-lubricated bearings – showed “almost no wear at all”, with a measured diametric bearing clearance less than 0.30mm (0.012”) on the longest running Unit 1. All remaining turbines (Units 2 to 6) had very low measured diametric clearances of between 0.30 and 0.50mm (0.012” and 0.020”).

    Thordon Bearings' Sister Company T-G DNALOP Purchases Polish Hydropower Plant to Develop New Turbine Technology

    Mar 25, 2019
    Thordon Bearings' sister company T-G DNALOP has purchased the small Struzyska hydroplant in Pila, Poland, 180km south of its bearing and seal production facility, in Slupsk. The Struzyska plant operates three small turbines capable of generating 67kW of electrical power. Once two of the turbines have been refurbished and are back onsite, the Canada-headquartered company will operate the plant commercially, supplying electricity back to the grid.
