Turbine Francis
Trelleborg Sealing Solutions has been supplying Francis turbine manufacturers and power utility companies with high-performance bearings for many years. Orkot® self-lubricating bearings have replaced the classic greased bronze bearings on both new and refurbished Francis turbines for many years. Orkot® TLMM and Orkot® TXMM self-lubricating bearings eliminate the need for grease, allowing for a cleaner downstream environment. The unique low-friction capacity of Orkot® TXMM allows the material to operate completely dry or in submerged conditions. With excellent mechanical strength and wear resistance, this material performs with virtually no swell in water. Orkot® TLMM and Orkot® TXMM bearings are the proven choice for reliability, long life and superior customer service for Francis turbines.
Typical Operating Environment
Bearings used in Francis turbines are subjected to both wet and dry conditions, heavy side loads, misalignment and impact loads during their normal operating cycles. It is not uncommon to see bearing pressures as high as 2,000psi without the benefits of grease or water lubrication.
