High Heat Spells Problems for Traditional Bearings
 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
