Bridges develop considerable stresses on various component members due to temperature variation, dead and live loads, and wind. Maintaining stress at a minimum (or relieving it entirely) by permitting controlled movement has been a job performed by Lubrite bearings for more than 80 years. The lubricants provide a low coefficient of friction and are capable of withstanding extremely heavy static loads over long periods of time. Lubrite bearings offer the ultimate in ease of installation and economy of operation, and in many installations have proven that they are capable of outlasting the bridge itself.

Bearing systems in a hydroelectric facility must be able to withstand high static loads for pro- longed periods while partially or completely submerged. The installation environment is frequently subjected to icing, silt, and erosion – factors encouraging corrosive and galvanic action. Often the bearing’s inaccessibility and association with massive pieces of equipment necessitate a product that will provide trouble-free operation throughout its service life. And, under all these conditions, the bearing must perform the function for which it was designed – providing free movement of extreme loads at moderate speeds.

Lubrite provides bearings for all of the gate applications encountered in hydroelectric plants. Other areas with similar problems that utilize bearings to permit relative motion between two components are: penstock supports, sheaves, linkages, dogging devices, floating mooring bits, valves, and lifting mechanisms

Lubrite® bearings were originally developed for use in marine environments. When offshore energy exploration became a reality, Lubrite’s experience working in the highly corrosive marine environment became extremely valuable. Lubrite offshore products range from highly complex self aligning bearing assemblies to basic pins and shafts using corrosion resistant materials such as Inconel 625, 17-4 PH stainless steel and Monel.

Today, Lubrite bearings are being utilized in a variety of applications on offshore energy exploration equipment – from the decks of ships and drilling platforms – right down to the mud line. Some typical applications include fairleads, rudder post bearings, mooring mechanisms, cranes, chain guides, cardan joints, flare structures and many others.

Lubrite® bearings offer industry self-lubricating, maintenance-free performance resulting in overall cost savings and operational safety. Lubrite bearings span an “industrial gap” of operation outside the range of rolling element and other types of bearings. More strenuous demands on both industry and industrial equipment coupled with spiraling maintenance costs necessitated the development of a maintenance-free self-lubricating bearing system. Lubrite bearings meet this demand.

Stresses that develop in the structural members of buildings (and any other allied applications) can be effectively relieved with Lubrite bearings. Both the internal stress of component members and the magnitude of the forces transmitted to the sup- porting structure itself can be minimized. This basic principle applies to a variety of structure types such as: pollution-control precipitators, rotary bridges, vessel supports, auditoriums, stadiums, shopping centers, and many others.

Lubrite® has been a primary source for the development and manufacture of structural bearings and associated components for atomic energy applications since the inception of the nuclear reactor.

Some of the areas in which Lubrite bearings are being used in nuclear facilities are: main reactor vessel supports, steam generators, pumps, gas coolers, shutdown cooling blowers, boilers, heat exchangers, suction headers, nozzle and pipe sup- ports, sheaves, jousting mechanisms, manipulation pivots, safety-door hangers and blast-door trucks.
