  • Thrust bearing assembly for roof turbine
    Patent number: 5326313
    Abstract: The turbine head of a wind-powered turbine ventilator is rotatably supported on a spindle by a thrust bearing assembly. A thrust receptacle is mounted on the upper part of the turbine head to receive the supporting end of the spindle. A centering collar coupled to the lower end of the spindle limits lateral deflection of the turbine. The thrust bearing components are constructed of complementary materials, acetal resin and polyamide resin, which provide a self-lubricating effect when rubbed together.
