ABSTRACT:
A crankhandle assembly has a cylindrically-hollow handle member rotatably mounted on a shaft or core element. The shaft has complementary stepped contours at each end and the handle has bearing cups at each end positioned to form with said stepped contours a ball bearing race, a thrust bearing, and a handle race. The bearing cup elements are centered in the handle by axially and radially disposed fins.
