Steel and metals production creates problems for tradtional bearings because of the high heat and heavy loads. GRAPHALLOY® bearings provide a solution to these problems. Here is a really tough application:
This annealing furnace had an interior temperature in the range of 650??C. Bearings supporting the pinch rolls were located outside the furnace walls and reached temperatures up to 400??C due to heat transmitted through the furnace wall by the shaft.
The heat transmitted by the shaft through the oven wall to the bearing was causing lubrication failure. In addition, the movement (linear expansion) of the shaft caused problems well beyond the capability of any standard ball or roller bearing arrangement.
GRAPHALLOY high temperature bearings were installed in a metal adapter designed to fit the original bearing housings and solved the problem without a major redesign. With minimal investment, bearings failures and associated maintenance costs were reduced.
Even if your application isn't this tough, GRAPHALLOY bearings can solve your high temperature bearing problems. For more details contact tonys@ftlseals.co.uk This e-mail address is being protected from spambots.
