Waukesha Bearings supplies medium and thick wall journal bearings specifically designed for turbomachinery. Several configurations are available to handle application needs for load capacity, rotating load, stiffness, damping, and rotordynamic stability.
The addition of grooves to fixed profile bearings can reduce destabilizing effects due to fluid rotation, while alterations to the circular geometry provide additional stability gains.
Performance can also be optimized through bearing material and lubrication method. Lubrication may be pressure fed or self-lubrication, the latter typically with an oil ring. Polymer linings can be used to extend performance limits or withstand high ambient temperatures. Hydrostatic jacking is recommended for machines with high start-up loads.
