Products Catalog

CON-SERV offers a variety of alloys which are approved for nuclear, structural, industrial and bridge applications.
These bronzes are lubricated to approximately 25% of the bearing surface. The standard lubricant takes temperatures to 250°F.
Lube 1 has a temperature range from 200°F to 500°F. Lube 2 has a temperature range from 500°F to 800°F. For nuclear applications (normal containment, atmosphere including borated water spray, and radiation below 2.2 x 106 rads.). Use Lube AE for all temperatures to 800°F. Slots and holes if required shall be fabricated in the bearing manufacturer's plant.
Designers use 15% friction factor as a practical figure and increase this for high temperature applications (greater than 500°F.) Any mating steel surfaces should be finished to a 63 to 125 RMS.
Bronze bearings are cast, machined and lubricated. Edges should be specified "as-cast" or machined.
For alloy C90500 Modified, the maximum design pressure is 800 psi at 600°F. For alloy C86300, the maximum design pressure is 1000 psi at 800°F. A straight line interpolation is appropriate between the 250°F design pressure and the maximum use temperature pressure.
