Case Histories
Orkot® TXMM Successful for Boise White Paper
Boise White Paper, a major manufacturer and supplier of paper, has found success with Trelleborg Sealing Solution’s Orkot® Hydro Bearings. Orkot® TXMM bearings were used to upgrade the wicket gates at Boise White Paper’s International Falls hydro facility along the Rainy River between Minnesota and the Canadian province of Ontario. This success has led Boise White Paper to replace our competitor’s bushings on the hydro facility’s main shafts with Orkot® TXMM. The dimensional stability of the Orkot® TXMM material was cited as the reason for the upgrade.
The International Falls facility houses seven turbine generators and has a capacity of 11,300 KW. Turbines #1 through #4 were upgraded in 1990 using our competition’s Lubron AQ 100 bushings. Boise White Paper had endured poor performance as a result. The wicket gates and operating arm linkages were continuously binding, and it was necessary for a chain fall to open and close the wicket gates for timing and inspection. Broken shafts were also a persistent problem. Trelleborg Sealing Solutions Eugene recommended the use of the Orkot® TXMM bushings, and they were installed in turbine #2 in 2006.
Once the Orkot® TXMM bushings were in place, Boise White Paper reported immediate positive results. A mechanic was able to move the operating arm by hand and there was no more overshoot or undershoot with the speed control. The unit was placed online automatically, without operator assistance, for the very first time since the start up of the facility.
