Abstract
The outer race of a roller bearing sheave is omitted so that the bearings are in direct engagement with a line. A retainer for the ends of the bearings is provided to allow the bearings to rotate and recirculate around an inner race. The rollers deflect portions of the line equally to equalize the load and to prevent high stresses on individual rollers.
