An assembly and method is provided for properly securing a device such as a bearing, pulley, sheave or the like to a shaft wherein a split tapered adapter is received about the shaft, the adapter having a first end of lesser diameter, a second end of greater diameter, and a tapered surface therebetween, and threads defined about the first end of the adapter, a locknut is in threaded engagement with the first end of the adapter and a device received about the adapter. The locknut has a set of set screws carried therethrough and spaced therearound which are controlled such that the force developed thereby is adequate to clamp the adapter to the shaft and seat the device on the adapter yet is inadequate to move the device toward the second end of the adapter. A second plurality of set screws may be received through said locknut which generate adequate force to move the device up the adapter to achieve a predetermined location of the device. Alternatively, the locknut may be turned a predetermined member of degrees of rotation to force the device up the adapter by a predetermined amount. The adapter and locknut are also claimed.

An improved bearing assembly for securement to a shaft, comprising: a tapered adapter of a size for receipt on said shaft, said adapter having a first end of lesser diameter and a second end of a diameter greater than said diameter of said first end and having a tapered outer surface therebetween, said first end of said adapter defining threads therearound for a portion of the length of same, and said adapter defining a radial opening therethrough and extending along the length thereof; a bearing received about said adapter adjacent said first end of same; a locknut received about said first end of said adapter in threaded engagement therewith, said locknut defining a plurality of threaded openings therethrough in a direction generally parallel to the length of said adapter; and a plurality of elements received in said openings in threaded engagement therewith, said elements being capable collectively upon turning of generating a force adequate only to clamp said adapter to a shaft passing therethrough and seat the bearing on the adapter while being inadequate to move said bearing up the tapered surface of said adapter.
